Apollo clientOptions using file configuration
⚠️ 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.jsexportdefault(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',}}
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
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.
Authentication
You have following methods for authentication available:
// set your graphql-tokenthis.$apolloHelpers.onLogin(token/* if not default you can pass in client as second argument, you can set custom cookies attributes object as the third argument, and you can skip reset store as the fourth argument */)// unset your graphql-tokenthis.$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.$apolloHelpers.getToken(/* you can provide named tokenName if not 'apollo-token' */)
// ~/middleware/isAuth.jsexportdefault({app, error})=>{consthasToken=!!app.$apolloHelpers.getToken()if(!hasToken){error({errorCode:503,message:'You are not allowed to see this'})}}
Examples to access the defaultClient of your apolloProvider
access client or call mutations and queries of any method inside of component
// ~/components/my-component.jsexportdefault{methods: {foo(){// receive the associated Apollo client constclient=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
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
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 choos
