# Command Line Interface

The following is a comprehensive reference of the Redwood CLI. You can get a glimpse of all the commands by scrolling the aside to the right.

The Redwood CLI has two entry-point commands:

  1. redwood (alias rw), which is for developing an application, and
  2. redwood-tools (alias rwt), which is for contributing to the framework.

This document covers the redwood command . For redwood-tools, see Contributing in the Redwood repo.

A Quick Note on Syntax

We use yargs and borrow its syntax here:

yarn rw generate page <name> [path] --option

  • rw g page is the command.
  • <name> and [path] are positional arguments.
    • <> denotes a required argument.
    • [] denotes an optional argument.
  • --option is an option.

Every argument and option has a type. Here <name> and [path] are strings and --option is a boolean.

You'll also sometimes see arguments with trailing .. like:

yarn rw build [side..]

The .. operator indicates that the argument accepts an array of values. See Variadic Positional Arguments.

# build

Build for production.

yarn rw build [side..]

We use Babel to transpile the api side into ./api/dist and Webpack to package the web side into ./web/dist.

Arguments & Options Description
side Which side(s) to build. Choices are api and web. Defaults to api and web
--stats Use Webpack Bundle Analyzer to visualize the size of Webpack output files via an interactive zoomable treemap
--verbose, -v Print more information while building

Usage

See Builds.

Example

Running yarn rw build without any arguments generates the Prisma client and builds both sides of your project:

~/redwood-app$ yarn rw build
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw build
  ✔ Generating the Prisma client...
  ✔ Building "api"...
  ✔ Building "web"...
Done in 17.37s.

Files are output to each side's dist directory:

├── api
│   ├── dist│   ├── prisma
│   └── src
└── web
    ├── dist    ├── public
    └── src

# check (alias diagnostics)

Get structural diagnostics for a Redwood project (experimental).

yarn rw check

Example

~/redwood-app$ yarn rw check
yarn run v1.22.4
web/src/Routes.js:14:5: error: You must specify a 'notfound' page
web/src/Routes.js:14:19: error: Duplicate Path
web/src/Routes.js:15:19: error: Duplicate Path
web/src/Routes.js:17:40: error: Page component not found
web/src/Routes.js:17:19: error (INVALID_ROUTE_PATH_SYNTAX): Error: Route path contains duplicate parameter: "/{id}/{id}"

# console (alias c)

Launch an interactive Redwood shell (experimental):

  • This has not yet been tested on Windows.
  • The Prisma Client must be generated prior to running this command, e.g. yarn rw db up. This is a known issue.
yarn rw console

Right now, you can only use the Redwood console to interact with your database:

Example

~/redwood-app$ yarn rw console
yarn run v1.22.4
> await db.user.findMany()
> [ { id: 1, email: 'tom@redwoodjs.com', name: 'Tom'  } ]

# dataMigrate

Data migration tools.

yarn rw dataMigrate <command>

Command Description
install Appends DataMigration model to schema.prisma, creates api/db/dataMigrations directory
up Executes outstanding data migrations

# install

  • Appends a DataMigration model to schema.prisma for tracking which data migrations have already run.
  • Creates a DB migration using yarn rw prisma migrate dev --create-only create_data_migrations.
  • Creates api/db/dataMigrations directory to contain data migration scripts
yarn rw dataMigrate install

# up

Executes outstanding data migrations against the database. Compares the list of files in api/db/dataMigrations to the records in the DataMigration table in the database and executes any files not present.

If an error occurs during script execution, any remaining scripts are skipped and console output will let you know the error and how many subsequent scripts were skipped.

yarn rw dataMigrate up

# db

Database tools.

WARNING

As of v0.25, yarn rw db <command> has been deprecated in favor of yarn rw prisma <command>. Click here to skip to the prisma section below.

# generate

Generate the Prisma client.

WARNING

As of v0.25, yarn rw db <command> has been deprecated in favor of yarn rw prisma <command>. Click here to skip to the prisma section below.

yarn rw db generate

The Prisma client is auto-generated and tailored to your schema.prisma. This means that yarn rw db generate needs to be run after every change to your schema.prisma for your Prisma client to be up to date. But you usually won't have to do this manually as other Redwood commands run this behind the scenes.

# introspect

Introspect your database and generate models in ./api/db/schema.prisma, overwriting existing models.

WARNING

As of v0.25, yarn rw db <command> has been deprecated in favor of yarn rw prisma <command>. Click here to skip to the prisma section below.

yarn rw db introspect

# save

Create a new migration.

WARNING

As of v0.25, yarn rw db <command> has been deprecated in favor of yarn rw prisma <command>. Click here to skip to the prisma section below.

yarn rw db save [name..]

A migration defines the steps necessary to update your current schema.

Argument Description
name Name of the migration

Running yarn rw db save generates the following directories and files as necessary:

api/db/migrations
├── 20200516162516-create-users
│   ├── README.md
│   ├── schema.prisma
│   └── steps.json
└── migrate.lock

  • migrations: A directory to store migrations.
  • migrations/<migration>: A directory for a specific migration. The name (<migration>) is composed of a timestamp of when it was created and the name given during yarn rw db save.
  • migrations/<migration>/README.md: A human-readable description of the migration, including metadata like when the migration was created and by who, a list of the actual migration changes, and a diff of the changes made to schema.prisma.
  • migrations/<migration>/schema.prisma: The schema that will be created if the migration is applied.
  • migrations/<migration>/steps.json: An alternate representation of the migration steps that will be applied.
  • migrate.lock: A lock file specifying the current migration.

# seed

Seed your database with test data.

WARNING

As of v0.25, yarn rw db <command> has been deprecated in favor of yarn rw prisma <command>. Click here to skip to the prisma section below.

yarn rw db seed

Runs seed.js in ./api/db. seed.js instantiates the Prisma client and provides an async main function where you can put any seed data—data that needs to exist for your app to run. See the example blog's seed.js file.

# studio

Start Prisma Studio, a visual editor for your database.

WARNING

As of v0.25, yarn rw db <command> has been deprecated in favor of yarn rw prisma <command>. Click here to skip to the prisma section below.

├── 20200518160811-add-posts     <-- desired└── migrate.lock

we could get to 20200518160811-add-posts by running:

~/redwood-app$ yarn rw db up 2

# dev

Start development servers for api and web.

yarn redwood dev [side..]

yarn rw dev api starts the Redwood dev server and yarn rw dev web starts the Webpack dev server with Redwood's config.

Argument Description
side Which dev server(s) to start. Choices are api and web. Defaults to api and web
--forward, --fwd String of one or more Webpack Dev Server config options. See example usage below. See the Redwood Webpack Doc for more details and examples.

Usage

If you're only working on your sdl and services, you can run just the api server to get GraphQL Playground on port 8911:

~/redwood-app$ yarn rw dev api
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw dev api
$ /redwood-app/node_modules/.bin/dev-server
15:04:51 api | Listening on http://localhost:8911
15:04:51 api | Watching /home/dominic/projects/redwood/redwood-app/api
15:04:51 api |
15:04:51 api | Now serving
15:04:51 api |
15:04:51 api | ► http://localhost:8911/graphql/

Using --forward (alias --fwd), you can pass one or more Webpack Dev Server config options. The following will run the dev server, set the port to 1234, and disable automatic browser opening.

~/redwood-app$ yarn rw dev --fwd="--port=1234 --open=false"

You may need to access your dev application from a different host, like your mobile device. To resolve the “Invalid Host Header” message, run the following:

~/redwood-app$ yarn rw dev --fwd="--disable-host-check"

For the full list of Webpack Dev Server settings, see this documentation.

# deploy

Deploy your redwood project to a hosting provider target.

For Jamstack hosting providers like Netlify and Vercel, the deploy command runs the set of steps to build, apply production DB changes, and apply data migrations. In this context, it is often referred to as a Build Command.

For hosting providers like AWS, this command runs the steps to both build your project and deploy it to AWS.

Undoing a Generator with a Destroyer

Most generate commands (i.e., everything but yarn rw generate dataMigration) can be undone by their corresponding destroy command. For example, yarn rw generate cell can be undone with yarn rw d cell.

# cell

Generate a cell component.

yarn rw generate cell <name>

Cells are signature to Redwood. We think they provide a simpler and more declarative approach to data fetching.

Arguments & Options Description
name Name of the cell
--force, -f Overwrite existing files
--javascript, --js Generate JavaScript files
--typescript, --ts Generate TypeScript files
--tests Generate test files [default: true]
--stories Generate Storybook files [default: true]

Usage

See the Cells section of the Tutorial.

Destroying

yarn rw d cell <name>

Example

Generating a user cell:

~/redwood-app$ yarn rw generate cell user
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g cell user
  ✔ Generating cell files...
    ✔ Writing `./web/src/components/UserCell/UserCell.test.js`...
    ✔ Writing `./web/src/components/UserCell/UserCell.js`...
Done in 1.00s.

A cell defines and exports four constants: QUERY, Loading, Empty, Failure, and Success:

// ./web/src/components/UserCell/UserCell.js

export const QUERY = gql`
  query {
    user {
      id
    }
  }
`

export const Loading = () => <div>Loading...</div>

export const Empty = () => <div>Empty</div>

export const Failure = ({ error }) => <div>Error: {error.message}</div>

export const Success = ({ user }) => {
  return JSON.stringify(user)
}

# component

Generate a component.

yarn rw generate component <name>

Redwood loves function components and makes extensive use of React Hooks, which are only enabled in function components.

Arguments & Options Description
name Name of the component
--force, -f Overwrite existing files
--javascript, --js Generate JavaScript files
--typescript, --ts Generate TypeScript files
--tests Generate test files [default: true]
--stories Generate Storybook files [default: true]

Destroying

yarn rw d component <name>

Example

Generating a user component:

~/redwood-app$ yarn rw generate component user
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g component user
  ✔ Generating component files...
    ✔ Writing `./web/src/components/User/User.test.js`...
    ✔ Writing `./web/src/components/User/User.js`...
Done in 1.02s.

The component will export some jsx telling you where to find it.

// ./web/src/components/User/User.js

const User = () => {
  return (
    <div>
      <h2>{'User'}</h2>
      <p>{'Find me in ./web/src/components/User/User.js'}</p>
    </div>
  )
}

export default User

# dataMigration

Generate a data migration script.

yarn rw generate dataMigration <name>

Creates a data migration script in api/db/dataMigrations.

Arguments & Options Description
name Name of the data migration, prefixed with a timestamp at generation time

Usage

See the Data Migration docs.

Usage

See the Deploy docs.

# function

Generate a Function.

yarn rw generate function <name>

Not to be confused with Javascript functions, Capital-F Functions are meant to be deployed to serverless endpoints like AWS Lambda.

Arguments & Options Description
name Name of the function
--force, -f Overwrite existing files

Usage

See the Custom Function recipe.

Destroying

yarn rw d function <name>

Example

Generating a user function:

~/redwood-app$ yarn rw generate function user
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g function user
  ✔ Generating function files...
    ✔ Writing `./api/src/functions/user.js`...
Done in 16.04s.

Functions get passed context which provides access to things like the current user:

// ./api/src/functions/user.js

export const handler = async (event, context) => {
  return {
    statusCode: 200,
    body: `user function`,
  }
}

Now if we run yarn rw dev api:

~/redwood-app$ yarn rw dev api
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw dev api
$ /redwood-app/node_modules/.bin/dev-server
17:21:49 api | Listening on http://localhost:8911
17:21:49 api | Watching /home/dominic/projects/redwood/redwood-app/api

Layouts wrap pages and help you stay DRY.

Arguments & Options Description
name Name of the layout
--force, -f Overwrite existing files
--javascript, --js Generate JavaScript files
--typescript, --ts Generate TypeScript files
--tests Generate test files [default: true]
--stories Generate Storybook files [default: true]

Usage

See the Layouts section of the tutorial.

Destroying

Example

Generating a user layout:

~/redwood-app$ yarn rw generate layout user
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g layout user
  ✔ Generating layout files...
    ✔ Writing `./web/src/layouts/UserLayout/UserLayout.test.js`...
    ✔ Writing `./web/src/layouts/UserLayout/UserLayout.js`...
Done in 1.00s.

A layout will just export it's children:

// ./web/src/layouts/UserLayout/UserLayout.test.js

const UserLayout = ({ children }) => {
  return <>{children}</>
}

export default UserLayout

# page

Generates a page component and updates the routes.

yarn rw generate page <name> [path]

path can include a route parameter which will be passed to the generated page. The syntax for that is /path/to/page/{routeParam}/more/path. You can also specify the type of the route parameter if needed: {routeParam:Int}. If path isn't specified, or if it's just a route parameter, it will be derived from name and the route parameter, if specified, will be added to the end.

This also updates Routes.js in ./web/src.

Arguments & Options Description
name Name of the page
path URL path to the page. Defaults to name
--force, -f Overwrite existing files
--tests Generate test files [default: true]
--stories Generate Storybook files [default: true]

Destroying

yarn rw d page <name> [path]

Examples

Generating a home page:

~/redwood-app$ yarn rw generate page home /
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g page home /
  ✔ Generating page files...
    ✔ Writing `./web/src/pages/HomePage/HomePage.test.js`...
    ✔ Writing `./web/src/pages/HomePage/HomePage.js`...
  ✔ Updating routes file...
Done in 1.02s.

The page returns jsx telling you where to find it:

// ./web/src/pages/HomePage/HomePage.js

const HomePage = () => {
  return (
    <div>
      <h1>HomePage</h1>
      <p>Find me in ./web/src/pages/HomePage/HomePage.js</p>
    </div>
  )
}

export default HomePage

And the route is added to Routes.js:

// ./web/src/Routes.js

const Routes = () => {
  return (
    <Router>
      <Route path="/" page={HomePage} name="home" />      <Route notfound page={NotFoundPage} />
    </Router>
  )
}

Generating a page to show quotes:

~/redwood-app$ yarn rw generate page quote {id}
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g page quote {id}
  ✔ Generating page files...
    ✔ Writing `./web/src/pages/QuotePage/QuotePage.stories.js`...
    ✔ Writing `./web/src/pages/QuotePage/QuotePage.test.js`...
    ✔ Writing `./web/src/pages/QuotePage/QuotePage.js`...
  ✔ Updating routes file...
Done in 1.02s.

The generated page will get the route parameter as a prop:

// ./web/src/pages/QuotePage/QuotePage.js

import { Link, routes } from '@redwoodjs/router'

const QuotePage = ({ id }) => {  return (
    <>
      <h1>QuotePage</h1>
      <p>Find me in "./web/src/pages/QuotePage/QuotePage.js"</p>
      <p>
        My default route is named "quote", link to me with `
        <Link to={routes.quote({ id: 42 })}>Quote 42</Link>`      </p>
      <p>The parameter passed to me is {id}</p>    </>
  )
}

export default QuotePage

And the route is added to Routes.js, with the route parameter added:

// ./web/src/Routes.js

const Routes = () => {
  return (
    <Router>
      <Route path="/quote/{id}" page={QuotePage} name="quote" />      <Route notfound page={NotFoundPage} />
    </Router>
  )
}

# scaffold

Generate Pages, SDL, and Services files based on a given DB schema Model. Also accepts <path/model>.

yarn rw generate scaffold <model>

A scaffold quickly creates a CRUD for a model by generating the following files and corresponding routes:

  • sdl
  • service
  • layout
  • pages
  • cells
  • components

The content of the generated components is different from what you'd get by running them individually.

Arguments & Options Description
model Model to scaffold. You can also use <path/model> to nest files by type at the given path directory (or directories). For example, rw g scaffold admin/post
--force, -f Overwrite existing files
--javascript, --js Generate JavaScript files
--typescript, --ts Generate TypeScript files

Usage

See Creating a Post Editor.

You can namespace your scaffolds by providing <path/model>. The layout, pages, cells, and components will be nested in newly created dir(s). For example, given a model user, running yarn rw generate scaffold admin/user will nest the layouts, pages, and components in a newly created admin directory:

~/redwood-app$ yarn rw generate scaffold admin/user
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g scaffold admin/user
  ✔ Generating scaffold files...
    ✔ Writing `./api/src/graphql/users.sdl.js`...
    ✔ Writing `./api/src/services/users/users.test.js`...
    ✔ Writing `./api/src/services/users/users.js`...
    ✔ Writing `./web/src/scaffold.css`...
    ✔ Writing `./web/src/layouts/Admin/UsersLayout/UsersLayout.js`...    ✔ Writing `./web/src/pages/Admin/EditUserPage/EditUserPage.js`...    ✔ Writing `./web/src/pages/Admin/UserPage/UserPage.js`...    ✔ Writing `./web/src/pages/Admin/UsersPage/UsersPage.js`...    ✔ Writing `./web/src/pages/Admin/NewUserPage/NewUserPage.js`...    ✔ Writing `./web/src/components/Admin/EditUserCell/EditUserCell.js`...    ✔ Writing `./web/src/components/Admin/User/User.js`...    ✔ Writing `./web/src/components/Admin/UserCell/UserCell.js`...    ✔ Writing `./web/src/components/Admin/UserForm/UserForm.js`...    ✔ Writing `./web/src/components/Admin/Users/Users.js`...    ✔ Writing `./web/src/components/Admin/UsersCell/UsersCell.js`...    ✔ Writing `./web/src/components/Admin/NewUser/NewUser.js`...  ✔ Adding scaffold routes...
  ✔ Adding scaffold asset imports...
Done in 1.21s.

The routes will be nested too:

// ./web/src/Routes.js

const Routes = () => {
  return (
    <Router>
      <Route path="/admin/users/new" page={AdminNewUserPage} name="adminNewUser" />      <Route path="/admin/users/{id:Int}/edit" page={AdminEditUserPage} name="adminEditUser" />      <Route path="/admin/users/{id:Int}" page={AdminUserPage} name="adminUser" />      <Route path="/admin/users" page={AdminUsersPage} name="adminUsers" />      <Route notfound page={NotFoundPage} />
    </Router>
  )
}

Destroying

yarn rw d scaffold <model>

# sdl

Generate a GraphQL schema and service object.

yarn rw generate sdl <model>

The sdl will inspect your schema.prisma and will do its best with relations. Schema to generators isn't one-to-one yet (and might never be).

Arguments & Options Description
model Model to generate the sdl for
--crud Also generate mutations
--force, -f Overwrite existing files
--javascript, --js Generate JavaScript files
--typescript, --ts Generate TypeScript files

Destroying

yarn rw d sdl <model>

Example

Generating a user sdl:

~/redwood-app$ yarn rw generate sdl user
yarn run v1.22.4
$ /redwood-app/node_modules/.bin/rw g sdl user
  ✔ Generating SDL files...
    ✔ Writing `./api/src/graphql/users.sdl.js`...
    ✔ Writing `./api/src/services/users/users.test.js`...
    ✔ Writing `./api/src/services/users/users.js`...
Done in 1.04s.

The generated sdl defines a corresponding type, query, and create/update inputs, without defining any mutations. To also get mutations, add the --crud option.

// ./api/src/graphql/users.sdl.js

export const schema = gql`
  type User {
    id: Int!
    email: String!
    name: String
  }

  type Query {
    users: [User!]!
  }

  input CreateUserInput {
    email: String!
    name: String
  }

  input UpdateUserInput {
    email: String
    name: String
  }
`

The services file fulfills the query. If the --crud option is added, this file will be much more complex.

// ./api/src/services/users/users.js

import { db } from 'src/lib/db'

export const users = () => {
  return db.user.findMany()
}

For a model with a relation, the field will be listed in the sdl:

// ./api/src/graphql/users.sdl.js

export const schema = gql`
  type User {
    id: Int!
    email: String!
    name: String
    profile: Profile  }

  type Query {
    users: [User!]!
  }

  input CreateUserInput {
    email: String!
    name: String
  }

  input UpdateUserInput {
    email: String
    name: String
  }
`

And the service will export an object with the relation as a property:

// ./api/src/services/users/users.js

import { db } from 'src/lib/db'

export const users = () => {
  return db.user.findMany()
}

export const User = {  profile: (_obj, { root }) => {    db.user.findUnique({ where: { id: root.id } }).profile(),  }}

# service

Generate a service component.

yarn rw generate service <name>

# lint

Lint your files.

yarn rw lint

Our ESLint configuration is a mix of ESLint's recommended rules, React's recommended rules, and a bit of our own stylistic flair:

  • no semicolons
  • comma dangle when multiline
  • single quotes
  • always use parenthesis around arrow functions
  • enforced import sorting

Option Description
--fix Try to fix errors

# open

Open your project in your browser.

yarn rw open

# prisma

Run Prisma CLI with experimental features.

yarn rw prisma

Redwood's prisma command is a lightweight wrapper around the Prisma CLI. It's the primary way you interact with your database.

What do you mean it's a lightweight wrapper?

By lightweight wrapper, we mean that we're handling some flags under the hood for you. You can use the Prisma CLI directly (yarn prisma), but letting Redwood act as a proxy (yarn redwood prisma) saves you a lot of keystrokes. For example, Redwood adds the --preview-feature and --schema=api/db/schema.prisma flags automatically.

If you want to know exactly what yarn redwood prisma <command> runs, which flags it's passing, etc., it's right at the top:

$ yarn rw prisma introspect
yarn run v1.22.10
$ ~/redwood-app/node_modules/.bin/rw prisma introspectRunning prisma cli:
yarn prisma introspect --schema "~/redwood-app/api/db/schema.prisma"
...

Since yarn rw prisma is just an entry point into all the database commands that the Prisma CLI has to offer, we won't try to provide an exhaustive reference of everything you can do with it here. Instead what we'll do is focus on some of the most common commands; those that you'll be running on a regular basis, and how they fit into Redwood's workflows.

For the complete list of commands, see the Prisma CLI Reference. It's the authority.

Along with the CLI reference, bookmark Prisma's Migration Flows doc—it'll prove to be an invaluable resource for understanding yarn rw prisma migrate.

Command Description
db <command> Manage your database schema and lifecycle during development
generate Generate artifacts (e.g. Prisma Client)
migrate <command> Update the database schema with migrations

# db

Manage your database schema and lifecycle during development.

yarn rw prisma db <command>

The prisma db namespace contains commands that operate directly against the database.

# push

Push the state from your Prisma schema to your database.

👉 Quick link to the Prisma CLI Reference.

yarn rw prisma db push

This is your go-to command for prototyping changes to your Prisma schema (schema.prisma). Prior to to yarn rw prisma db push, there wasn't a great way to try out changes to your Prisma schema without creating a migration. This command fills the void by "pushing" your schema.prisma file to your database without creating a migration. You don't even have to run yarn rw prisma generate afterward—it's all taken care of for you, making it ideal for iterative development.

# seed

Seed your database.

👉 Quick link to the Prisma CLI Reference.

yarn rw prisma db seed

This command seeds your database by running your project's seed.js file (in api/db). Note that having a great seed might not be all that important at the start, but as soon as you start collaborating with others, it becomes vital.

Prisma's got some great resources on this command. You can code along with Ryan Chenkie, and learn how libraries like faker can help you create a large, realistic database fast, especially in tandem with Prisma's createMany. And Prisma's got a great seeding guide that covers both the concepts and the nuts and bolts.

# migrate

Update the database schema with migrations.

👉 Quick link to the Prisma Concepts.

yarn rw prisma migrate <command>

As a database toolkit, Prisma strives to be as holistic as possible. Prisma Migrate lets you use Prisma schema to make changes to your database declaratively, all while keeping things deterministic and fully customizable by generating the migration steps in a simple, familiar format: SQL.

Since migrate generates plain SQL files, you can edit those SQL files before applying the migration using yarn rw prisma migrate --create-only. This creates the migration based on the changes in the Prisma schema, but doesn't apply it, giving you the chance to go in and make any modifications you want. Daniel Norman's tour of Prisma Migrate demonstrates this and more to great effect.

Prisma Migrate has separate commands for applying migrations based on whether you're in dev or in production. The Prisma Migration flows goes over the difference between these workflows in more detail.

# dev

Create a migration from changes in Prisma schema, apply it to the database, trigger generators (e.g. Prisma Client).

👉 Quick link to the Prisma CLI Reference.

yarn rw prisma migrate dev

# deploy

Apply pending migrations to update the database schema in production/staging.

👉 Quick link to the Prisma CLI Reference.

yarn rw prisma migrate deploy

# upgrade

Upgrade all @redwoodjs packages via an interactive CLI.

yarn rw upgrade

This command does all the heavy-lifting of upgrading to a new release for you.

Besides upgrading to a new stable release, you can use this command to upgrade to either of our unstable releases, canary and rc, or you can upgrade to a specific release version.

A canary release is published to npm every time a PR is merged to the main branch, and when we're getting close to a new release, we publish release candidates.

Option Description
--dry-run, -d Check for outdated packages without upgrading
--tag, -t Choices are "canary", "rc", or a specific version (e.g. "0.19.3"). WARNING: Unstable releases in the case of "canary" and "rc", which will force upgrade packages to the most recent release of the specified tag.
--pr Installs packages for the given PR

Example

Upgrade to the most recent canary:

yarn redwood upgrade -t canary

Upgrade to a specific version:

yarn redwood upgrade -t 0.19.3

Upgrade using packages from PR #1714 (version tag provided in PR comments):

yarn rw upgrade --pr 1714:0.24.0-38ba18c
