Version: 0.14.0

Migration from 0.13.X to 0.14.X

Are you on 0.11.X or earlier?

This guide only covers the migration from 0.13.X to 0.14.X. If you are migrating from 0.11.X or earlier, please read the migration guide from 0.11.X to 0.12.X first.

What's new in 0.14.0?​

Using Prisma Schema file directly​

Before 0.14.0, users defined their entities in the .wasp file, and Wasp generated the schema.prisma file based on that. This approach had some limitations, and users couldn't use some advanced Prisma features.

Wasp now exposes the schema.prisma file directly to the user. You now define your entities in the schema.prisma file and Wasp uses that to generate the database schema and Prisma client. You can use all the Prisma features directly in the schema.prisma file. Simply put, the schema.prisma file is now the source of truth for your database schema.

main.wasp
app myApp {
  wasp: {
    version: "^0.13.0"
  },
  title: "MyApp",
  db: {
    system: PostgreSQL
  },
}

entity User {=psl
  id       Int @id @default(autoincrement())
  tasks    Task[]
psl=}

entity Task {=psl
  id          Int @id @default(autoincrement())
  description String
  isDone      Boolean
  userId      Int
  user        User @relation(fields: [userId], references: [id])
psl=}

Better auth user API​

Wasp introduced a much simpler API for accessing user auth fields like username, email or isEmailVerified on the user object. You don't need to use helper functions every time you want to access the user's username or do extra steps to get proper typing.

How to migrate?​

To migrate your app to Wasp 0.14.x, you must:

  1. Bump the version in main.wasp and update your tsconfig.json.
  2. Migrate your entities into the new schema.prisma file.
  3. Update code that accesses user fields.

Bump the version and update tsconfig.json​

Let's start with something simple. Update the version field in your Wasp file to ^0.14.0:

main.wasp
app MyApp {
  wasp: {
    version: "^0.14.0"
  },
}

To ensure your project works correctly with Wasp 0.14.0, you must also update your tsconfig.json file.

If you haven't changed anything in your project's tsconfig.json file (this is the case for most users), just replace its contents with the new version shown below.

If you have made changes to your tsconfig.json file, we recommend taking the new version of the file and reapplying them.

Here's the new version of the tsconfig.json file:

tsconfig.json
// =============================== IMPORTANT =================================
//
// This file is only used for Wasp IDE support. You can change it to configure
// your IDE checks, but none of these options will affect the TypeScript
// compiler. Proper TS compiler configuration in Wasp is coming soon :)
{
  "compilerOptions": {
    "module": "esnext",
    "target": "esnext",
    // We're bundling all code in the end so this is the most appropriate option,
    // it's also important for autocomplete to work properly.
    "moduleResolution": "bundler",
    // JSX support
    "jsx": "preserve",
    "strict": true,
    // Allow default imports.
    "esModuleInterop": true,
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "typeRoots": [
      // This is needed to properly support Vitest testing with jest-dom matchers.
      // Types for jest-dom are not recognized automatically and Typescript complains
      // about missing types e.g. when using `toBeInTheDocument` and other matchers.
      "node_modules/@testing-library",
      // Specifying type roots overrides the default behavior of looking at the
      // node_modules/@types folder so we had to list it explicitly.
      // Source 1: https://www.typescriptlang.org/tsconfig#typeRoots
      // Source 2: https://github.com/testing-library/jest-dom/issues/546#issuecomment-1889884843
      "node_modules/@types"
    ],
    // Since this TS config is used only for IDE support and not for
    // compilation, the following directory doesn't exist. We need to specify
    // it to prevent this error:
    // https://stackoverflow.com/questions/42609768/typescript-error-cannot-write-file-because-it-would-overwrite-input-file
    "outDir": ".wasp/phantom"
  }
}

Migrate to the new schema.prisma file​

To use the new schema.prisma file, you need to move your entities from the .wasp file to the schema.prisma file.

1. Create a new schema.prisma file

Create a new file named schema.prisma in the root of your project:

.
├── main.wasp
...
├── schema.prisma
├── src
├── tsconfig.json
└── vite.config.ts

2. Add the datasource block to the schema.prisma file

This block specifies the database type and connection URL:

schema.prisma
datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

  • The provider should be either "postgresql" or "sqlite".

  • The url must be set to env("DATABASE_URL") so that Wasp can inject the database URL from the environment variables.

3. Add the generator block to the schema.prisma file

This block specifies the Prisma Client generator Wasp uses:

schema.prisma
datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}
  • The provider should be set to "prisma-client-js".

4. Move your entities to the schema.prisma file

Move the entities from the .wasp file to the schema.prisma file:

schema.prisma
datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

// There are some example entities, you should move your entities here
model User {
  id       Int @id @default(autoincrement())
  tasks    Task[]
}

model Task {
  id          Int @id @default(autoincrement())
  description String
  isDone      Boolean
  userId      Int
  user        User @relation(fields: [userId], references: [id])
}

When moving the entities over, you'll need to change entity to model and remove the =psl and psl= tags.

If you had the following in the .wasp file:

main.wasp
entity Task {=psl
  // Stays the same
psl=}

... it would look like this in the schema.prisma file:

schema.prisma
model Task {
  // Stays the same
}

5. Remove app.db.system field from the Wasp file

We now configure the DB system in the schema.prisma file, so there is no need for that field in the Wasp file.

main.wasp
app MyApp {
  // ...
  db: {
    system: PostgreSQL,
  }
}

6. Migrate Prisma preview features config to the schema.prisma file

If you didn't use any Prisma preview features, you can skip this step.

If you had the following in the .wasp file:

main.wasp
app MyApp {
  // ...
  db: {
    prisma: {
      clientPreviewFeatures: ["postgresqlExtensions"]
      dbExtensions: [
        { name: "hstore", schema: "myHstoreSchema" },
        { name: "pg_trgm" },
        { name: "postgis", version: "2.1" },
      ]
    }
  }
}

... it will become this:

schema.prisma
datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
  extensions = [hstore(schema: "myHstoreSchema"), pg_trgm, postgis(version: "2.1")]
}

generator client {
  provider = "prisma-client-js"
  previewFeatures = ["postgresqlExtensions"]
}

All that's left to do is migrate the database.

To avoid type errors, it's best to take care of database migrations after you've migrated the rest of the code. So, just keep reading, and we will remind you to migrate the database as the last step of the migration guide.

Migrate how you access user auth fields​

We had to make a couple of breaking changes to reach the new simpler API.

Follow the steps below to migrate:

  1. Replace the getUsername helper with user.identities.username.id

    If you didn't use the getUsername helper in your code, you can skip this step.

    This helper changed and it no longer works with the user you receive as a prop on a page or through the context. You'll need to replace it with user.identities.username.id.

    src/MainPage.tsx
    import { getUsername, AuthUser } from 'wasp/auth'

    const MainPage = ({ user }: { user: AuthUser }) => {
      const username = getUsername(user)
      // ...
    }
    src/tasks.ts
    import { getUsername } from 'wasp/auth'

    export const createTask: CreateTask<...>  = async (args, context) => {
        const username = getUsername(context.user)
        // ...
    }

  2. Replace the getEmail helper with user.identities.email.id

    If you didn't use the getEmail helper in your code, you can skip this step.

    This helper changed and it no longer works with the user you receive as a prop on a page or through the context. You'll need to replace it with user.identities.email.id.

    src/MainPage.tsx
    import { getEmail, AuthUser } from 'wasp/auth'

    const MainPage = ({ user }: { user: AuthUser }) => {
      const email = getEmail(user)
      // ...
    }
    src/tasks.ts
    import { getEmail } from 'wasp/auth'

    export const createTask: CreateTask<...>  = async (args, context) => {
        const email = getEmail(context.user)
        // ...
    }

  3. Replace accessing providerData with user.identities.<provider>.<value>

    If you didn't use any data from the providerData object, you can skip this step.

    Replace <provider> with the provider name (for example username, email, google, github, etc.) and <value> with the field you want to access (for example isEmailVerified).

    src/MainPage.tsx
    import { findUserIdentity, AuthUser } from 'wasp/auth'

    function getProviderData(user: AuthUser) {
      const emailIdentity = findUserIdentity(user, 'email')
      // We needed this before check for proper type support
      return emailIdentity && 'isEmailVerified' in emailIdentity.providerData
        ? emailIdentity.providerData
        : null
    }

    const MainPage = ({ user }: { user: AuthUser }) => {
      const providerData = getProviderData(user)
      const isEmailVerified = providerData ? providerData.isEmailVerified : null
      // ...
    }

  4. Use getFirstProviderUserId directly on the user object

    If you didn't use getFirstProviderUserId in your code, you can skip this step.

    You should replace getFirstProviderUserId(user) with user.getFirstProviderUserId().

    src/MainPage.tsx
    import { getFirstProviderUserId, AuthUser } from 'wasp/auth'

    const MainPage = ({ user }: { user: AuthUser }) => {
      const userId = getFirstProviderUserId(user)
      // ...
    }
    src/tasks.ts
    import { getFirstProviderUserId } from 'wasp/auth'

    export const createTask: CreateTask<...>  = async (args, context) => {
        const userId = getFirstProviderUserId(context.user)
        // ...
    }

  5. Replace findUserIdentity with checks on user.identities.<provider>

    If you didn't use findUserIdentity in your code, you can skip this step.

    Instead of using findUserIdentity to get the identity object, you can directly check if the identity exists on the identities object.

    src/MainPage.tsx
    import { findUserIdentity, AuthUser } from 'wasp/auth'

    const MainPage = ({ user }: { user: AuthUser }) => {
      const usernameIdentity = findUserIdentity(user, 'username')
      if (usernameIdentity) {
        // ...
      }
    }
    src/tasks.ts
    import { findUserIdentity } from 'wasp/auth'

    export const createTask: CreateTask<...>  = async (args, context) => {
        const usernameIdentity = findUserIdentity(context.user, 'username')
        if (usernameIdentity) {
            // ...
        }
    }

Migrate the database​

Finally, you can Run the Wasp CLI to regenerate the new Prisma client:

wasp db migrate-dev

This command generates the Prisma client based on the schema.prisma file.

Read more about the Prisma Schema File and how Wasp uses it to generate the database schema and Prisma client.

That's it!

You should now be able to run your app with the new Wasp 0.14.0. We recommend reading through the updated Accessing User Data section to get a better understanding of the new API.
