Apollo inside of NuxtJS

npm version license

Warning

This version requires Vue 2.6+ with serverPrefetch support. For example:

npm install --save vue@2.6.6 vue-template-compiler@2.6.6 vue-server-renderer@2.6.6

Sometime you may need to remove/rebuild package-lock.json/yarn.lock to make it work.

Setup

1- Install apollo module

npm install --save @nuxtjs/apollo

or

yarn add @nuxtjs/apollo

2- Load @nuxtjs/apollo module

// nuxt.config.js

export default {
  modules: [
    '@nuxtjs/apollo',
  ],

  apollo: {
    clientConfigs: {
      default: {
        httpEndpoint: 'http://localhost:4000',
      }
    }
  }
}

3- Loading *.gql or *.graphql files (optional)

Install graphql-tag

npm install --save graphql-tag

or

yarn add graphql-tag

:warning: Typescript users

Add a gql.d.ts file in your sources folder with the following content:

declare module '*.gql' {
  import { DocumentNode } from 'graphql'

  const content: DocumentNode
  export default content
}

declare module '*.graphql' {
  import { DocumentNode } from 'graphql'

  const content: DocumentNode
  export default content
}

Usage

You have a successfully enabled vue-apollo in your project.

Checkout Official example and vue-apollo official documentation for how to use vue-apollo inside your application

Advanced configuration

Apollo clientOptions using file configuration

:warning: In case you need to declare functions (like getAuth or inMemoryCacheOptions.fragmentMatcher) inside apollo configuration, you MUST define your clientOptions using an external file

// ~/plugins/my-alternative-apollo-config.js

export default (context) => {
  return {
    httpEndpoint: 'http://localhost:4000/graphql-alt',

    /*
     * For permanent authentication provide `getAuth` function.
     * The string returned will be used in all requests as authorization header
     */
    getAuth: () => 'Bearer my-static-token',
  }
}

watchLoading example

// ~/plugins/apollo-watch-loading-handler.js

export default (isLoading, countModifier, nuxtContext) => {
  loading += countModifier
  console.log('Global loading', loading, countModifier)
}

errorHandler example

// ~/plugins/apollo-error-handler.js

export default ({ graphQLErrors, networkError, operation, forward }, nuxtContext) => {
  console.log('Global error handler')
  console.log(graphQLErrors, networkError, operation, forward)
}

Options

You can either (in a simple setup) just add an object as described above. If you need to overwrite cache or the default getAuth() function then use a path to your config file which returns the client config options.

clientConfigs Option: required

Sets up the apollo client endpoints. All available options for each endpoint you find here

Check out official vue-apollo-cli where possible usecases are presented.

clientConfigs.default Object: required

clientConfigs.<your-additional-client-key> Object|Path: optional

tokenName String: optional, default: 'apollo-token'

Token name for the cookie which will be set in case of authentication. You can also provide an option tokenName in each of your clientConfigs to overwrite the default. When each request is made, the value of whatever is in this cooke will be sent in an "Authorization" HTTP header as specified by authenticationType below.

authenticationType String: optional, default: 'Bearer'

Sets the authentication type for any authorized request. Modify this if the authentication type your GraphQL API requires is not the default Bearer. All requests will then be sent with the appropriate HTTP header in the format: "Authorization: <authenticationType> <your token taken from user cookies>" (Eg. Authorization: Bearer abc123).

If your backend requires an Authorization header in the format "Authorization: <your token>", without any prefix, then you should set this value to an empty string.

includeNodeModules Boolean: optional, default: false

In case you use *.gql files inside of node_module folder you can enable the graphql-tag/loader to parse the files for you.

Authentication

You have following methods for authentication available:

 // set your graphql-token
 this.$apolloHelpers.onLogin(token /* if not default you can pass in client as second argument, you can set custom cookies attributes object as the third argument, and you can skip reset store as the fourth argument */)
 // unset your graphql-token
 this.$apolloHelpers.onLogout(/* if not default you can pass in client as first argument, and you can skip reset store as the second argument */)
 // get your current token (we persist token in a cookie)
 this.$apolloHelpers.getToken(/* you can provide named tokenName if not 'apollo-token' */)

Check out the full example

User login

// ~/components/my-component.js

export default {
  methods: {
    async onSubmit () {
      const credentials = this.credentials
      try {
          const res = await this.$apollo.mutate({
              mutation: authenticateUserGql,
              variables: credentials
          }).then(({data}) => data && data.authenticateUser)
          await this.$apolloHelpers.onLogin(res.token)
      } catch (e) {
          console.error(e)
      }
    },
  }
}

User logout

// ~/components/my-component.js

export default {
  methods: {
    async onLogout () {
      await this.$apolloHelpers.onLogout()
    },
  }
}

getToken

// ~/middleware/isAuth.js

export default ({app, error}) => {
  const hasToken = !!app.$apolloHelpers.getToken()
  if (!hasToken) {
    error({
      errorCode:503, 
      message:'You are not allowed to see this'
    })
  }
}

Examples to access the defaultClient of your apolloProvider

Vuex actions
// ~/store/my-store.js

export default {
  actions: {
    foo (store, payload) {
      let client = this.app.apolloProvider.defaultClient
    }
  }
}
asyncData/fetch method of page component
// ~/components/my-component.js

export default {
  asyncData (context) {
    let client = context.app.apolloProvider.defaultClient
  }
}
nuxtServerInit
export default {
  nuxtServerInit (store, context) {
    let client = context.app.apolloProvider.defaultClient
  }
}
access client or call mutations and queries of any method inside of component
// ~/components/my-component.js

export default {
  methods: {
    foo () {
      // receive the associated Apollo client 
      const client = this.$apollo.getClient()

      // most likely you would call mutations like following:
      this.$apollo.mutate({mutation, variables})
      
      // but you could also call queries like this:
      this.$apollo.query({query, variables})
        .then(({ data }) => {
          // do what you want with data
        })
    }
  }
}

Once you get the client, you can access its methods and properties. See API Reference

Smart queries on any component

// nuxt.config.js

export default {
  apollo: {
    foo: {
      query: fooGql,
      variables () {
        return {
          myVar: this.myVar
        }
      }
    }
  }
}

See vue-apollo documentation for more information on smart queries

Add GQL file recognition on node_modules

// nuxt.config.js

export default {
  apollo: {
    clientConfigs: {
      default: '~/apollo/client-configs/default.js'
    },
    includeNodeModules: true
  }
}

Upgrade

Upgrade Guide apollo-module v3 => v4

Version 4 of this module leaves you with zero configuration. This means we use the best possible approach available from vue-cli-plugin-apollo and the same configuration behaviour. This means you don't need to wire up your own configuration, simply pass

Edit your configuration as following:

// nuxt.config.js

export default {
  apollo: {
    clientConfigs: {
      default:{
        httpEndpoint: YOUR_ENDPOINT,
        wsEndpoint: YOUR_WS_ENDPOINT
      }
    }
  }
}

Upgrade Guide apollo-client v1 => v2

Version 3 of this module is using apollo-client 2.x. You need to make sure to update all your middle/afterware according to the upgrade guide of apollo-client. Check this source for a reference: https://www.apollographql.com/docs/apollo-server/migration-two-dot/

Troubleshooting

Proxies

CORS errors are most often resolved with proxies. If you see a Cross-Origin-Request error in your client side console look into setting up a proxy. Check out https://github.com/nuxt-community/proxy-module for quick and straight forward setup.

ctx.req.session - req is undefined

This is just a placeholder. You'll want to replace it with whatever storage mechanism you choose to store your token. Here is an example using local storage : https://github.com/Akryum/vue-apollo/issues/144

Contribute and wire up setup

Setup the required fields in .env file in root folder

# cat .env
HTTP_ENDPOINT=https://your-endpoint
WS_ENDPOINT=wss://your-endpoint

In index.vue the login process requires that the gql endpoint enables a mutation which returns a valid token:

mutation authenticateUser($email:String!,$password:String!){
    authenticateUser(email: $email, password: $password) {
        token
        id
    }
}

If your gql backend is prepared start running nuxt as follow

npm install
npm run dev
