- Nuxt.js module to use vue-apollo
- uses internally same approach as vue-cli-plugin-apollo
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@2.6.6Sometime you may need to remove/rebuild package-lock.json/yarn.lock to make it work.
Install apollo module:
npm install --save @nuxtjs/apollo
# if you are using *.gql or *.graphql files add graphql-tag to your dependencies
npm install --save graphql-tagAdd @nuxtjs/apollo to modules section of nuxt.config.js

export default function(context){
return {
httpEndpoint: 'http://localhost:4000/graphql-alt',
getAuth:() => 'Bearer my-static-token' // use this method to overwrite functions
}
}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.
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.
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.
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: " (Eg. Authorization: Bearer abc123).
If your backend requires an Authorization header in the format "Authorization: ", without any prefix, then you should set this value to an empty string.
In case you use *.gql files inside of node_module folder you can enable the graphql-tag/loader to parse the files for you.
Once the setup is completed you have a successfully enabled vue-apollo in your project. Checkout Official example and vue-apollo how to use vue-apollo inside your application code
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.$apolloHelpers.getToken(/* you can provide named tokenName if not 'apollo-token' */)Check out the full example
For permanent authorization tokens the setup just provide getAuth function for each of your endpoint configurations:
apollo: {
clientConfigs: {
default: {
httpEndpoint: 'https://graphql.datocms.com',
getAuth: () => 'Bearer your_token_string'
},
}
},methods:{
async onSubmit () {
const credentials = this.credentials
try {
const res = await this.$apollo.mutate({
mutation: authenticateUserGql,
variables: credentials
}).then(({data}) => data && data.authenticateUser)
await this.$apolloHelpers.onLogin(res.token)
} catch (e) {
console.error(e)
}
},
}methods:{
async onLogout () {
await this.$apolloHelpers.onLogout()
},
}// middleware/isAuth.js
export default function ({app, error}) {
const hasToken = !!app.$apolloHelpers.getToken()
if (!hasToken) {
error({errorCode:503, message:'You are not allowed to see this'})
}
}export default {
actions: {
foo (store, payload) {
let client = this.app.apolloProvider.defaultClient
}
}
}export default {
asyncData (context) {
let client = context.app.apolloProvider.defaultClient
}
}export default {
nuxtServerInit (store, context) {
let client = context.app.apolloProvider.defaultClient
}
}export default {
methods:{
foo(){
// receive the associated Apollo client
const client = this.$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
export default {
apollo: {
foo: {
query: fooGql,
variables () {
return {
myVar: this.myVar
}
}
}
}
}See vue-apollo documentation for more information on smart queries
apollo: {
clientConfigs: {
default: '~/apollo/client-configs/default.js'
},
includeNodeModules: true
}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
apollo:{
clientConfigs:{
default:{
httpEndpoint: YOUR_ENDPOINT,
wsEndpoint: YOUR_WS_ENDPOINT
}
}
}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/
To use *gql|graphql files you need to add following dependency to your project:
yarn add graphql-tag
# alternative
npm install graphql-tag
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.
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 : vuejs/apollo#144
Setup the required fields in .env file in root folder
// .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
