Getting started

:warning: Make sure you have vue-cli 3.x.x:

vue --version

If you don’t have a project created with vue-cli 3.x yet:

vue create my-new-app

Navigate to the newly created project folder and add the cli plugin:

cd my-new-app
vue add apollo

:information_source: An example ApolloExample.vue component alongside some GraphQL query files will be added into your sources if you chose to include the examples.

Start your app:

npm run serve

Recommended VS Code extension

undefinedUpdating vue-cli-plugin-apollo will also update both Apollo Client and its configuration for you! :+1:undefined

Read the vue-apollo doc.

GraphQL API Server

If you enabled the GraphQL API Server, open a new terminal and start it:

npm run apollo

You can edit the files generated in the ./apollo-server folder:

• schema.graphql contains the Schema written with the schema definition language.
• resolvers.js declares the Apollo resolvers.
• context.js allows injecting a context object into all the resolvers (third argument).
• mocks.js defines the custom resolvers used for mocking (more info).
• directives.js defines the custom schema directives (more info)).

The server will be automatically restarted when a change is detected.

To run the server only once, use this command:

npm run run-graphql-api

undefinedUpdating vue-cli-plugin-apollo will also update the GraphQL Server service :+1:undefined

Injected Commands

• undefinedvue-cli-service apollo:watchundefined

  Run the GraphQL API server with info from ./apollo-server and watch the files to restart itself automatically.

• undefinedvue-cli-service apollo:runundefined

  Run the GraphQL API server with info from ./apollo-server once.

Configuration

Plugin options

The GraphQL API Server can be configured via the pluginOptions in vue.config.js:

module.exports = {
  // Other options...
  pluginOptions: {
    // Apollo-related options
    apollo: {
      // Enable automatic mocking
      enableMocks: true,
      // Enable Apollo Engine
      enableEngine: true,

      /* Other options (with default values) */

      // Cross-Origin options
      cors: '*',
      // Requests timeout (ms)
      timeout: 120000,
      // Integrated apollo engine
      integratedEngine: true,
      // Base folder for the server source files
      serverFolder: './apollo-server',
      // Apollo server options (will be merged with the included default options)
      serverOptions: {
        // ...
      },
    },
  },
}

See Apollo Server options.

Client state

You can use apollo-link-state for client-only local data with the clientState option of createApolloClient:

import { createApolloClient } from 'vue-cli-plugin-apollo/graphql-client'

const options = {
  // ...

  clientState: {
    defaults: {
      connected: false,
    },
    resolvers: {
      Mutation: {
        connectedSet: (root, { value }, { cache }) => {
          const data = {
            connected: value,
          }
          cache.writeData({ data })
        },
      },
    },
  },
}

const { apolloClient } = createApolloClient(options)

Then you need to use the @client directive:

query isConnected {
  connected @client
}

mutation setConnected ($value: Boolean!) {
  connectedSet (value: $value) @client
}

Authorization Header

By default, createApolloClient will retrieve the Authorization header value from localStorage. You can override this behavior with the getAuth option:

const options = {
  // ...

  getAuth: (tokenName) => getUserToken(),
}

const { apolloClient } = createApolloClient(options)

If you use cookies, you can return undefined.

Example apolloserver/context.js that validates the token and set userId on resolvers context:

import users from './connectors/users'

// Context passed to all resolvers (third argument)
// req => Query
// connection => Subscription
// eslint-disable-next-line no-unused-vars
export default ({ req, connection }) => {
  // If the websocket context was already resolved
  if (connection && connection.context) return connection.context

  let token
  // HTTP
  if (req) token = req.get('Authorization')
  // Websocket
  if (connection) token = connection.authorization

  // User validation
  let userId
  if (token && users.validateToken(token)) {
    userId = token.userId
  }

  return {
    token,
    userId,
  }
}

Mocks

You can enable automatic mocking on the GraphQL API Server. It can be customized in the ./apollo-server/mocks.js file generated in your project.

Directives

You can add custom GraphQL directives in the ./apollo-server/directives.js file (documentation).

import { SchemaDirectiveVisitor } from 'graphql-tools'

class PrivateDirective extends SchemaDirectiveVisitor {
  // ...
}

export default {
  // Now you can use '@private' in the schema
  private: PrivateDirective
}

Apollo Engine

Apollo Engine is a commercial product from Apollo. It enables lots of additional features like monitoring, error reporting, caching and query persisting.

Create a key at https://engine.apollographql.com (it’s free!).

Express middlewares

If you need to add express middlewares into the GraphQL server, you can create a ./apollo-server/server.js file:

import path from 'path'
import express from 'express'

const distPath = path.resolve(__dirname, '../../dist')

export default app => {
  app.use(express.static(distPath))
}

Env variables

• undefinedVUE_APP_GRAPHQL_HTTPundefined

  The url to the graphql HTTP endpoint, default: http://localhost:4000

• undefinedVUE_APP_GRAPHQL_WSundefined

  The url to the graphql Websockets endpoint for subscriptions, default: ws://localhost:4000

With the GraphQL server enabled

• undefinedVUE_APP_GRAPHQL_PORTundefined

  Port of the GraphQL API Server, default: 4000

• undefinedVUE_APP_APOLLO_ENGINE_KEYundefined

  API key for Apollo Engine

Injected webpack-chain Rules

• config.rule('gql')

Running the GraphQL server in production

Production app

cross-env NODE_ENV=production yarn run apollo:run --mode production

If you deploy on now.sh, add the following script to your package.json:

{
  "scripts": {
    "start": "cross-env NODE_ENV=production yarn run apollo:run --mode production" 
  }
}

Library published on npm

If your project is meant to be used as a package installed from npm, you will need to move vue-cli-plugin-apollo from the devDependencies field to dependencies in your package.json file. Then you can run the server:

const server = require('vue-cli-plugin-apollo/graphql-server')

const opts = {
  port: 4000,
  graphqlPath: '/graphql',
  subscriptionsPath: '/graphql',
  enableMocks: false,
  enableEngine: false,
  cors: '*',
  timeout: 1000000,
  quiet: true,
  paths: {
    typeDefs: require.resolve('some-folder/apollo-server/type-defs.js'),
    resolvers: require.resolve('some-folder/apollo-server/resolvers.js'),
    context: require.resolve('some-folder/apollo-server/context.js'),
    pubsub: require.resolve('some-folder/apollo-server/pubsub.js'),
    server: require.resolve('some-folder/apollo-server/server.js'),
    directives: require.resolve('some-folder/apollo-server/directives.js')
  }
}

server(opts, () => {
  console.log('Server is running!')
})

Manual code changes

In case the plugin isn’t able to modify the file containing the root Vue instance:

Import the provider:

import { createProvider } from './vue-apollo'

Then in the root instance, set the provide option:

new Vue({
  el: '#app',
  // Add this line
  apolloProvider: createProvider(),
})
