Queries Inspired by the way the Apollo Client is implemented for React (React-Apollo), Vue-Apollo provides us with a few components that we can use out of the box to manage the UI and state of our queries and mutations with a Vue component inside the template. vue-apollo-todos. You’ll start by implementing the AppLogincomponent. ← Now is the time to get your hands dirty and start out with an actual project! options: (default: null) Options object.Can also be a function returning an options object. →, mutation sendMessage ($input: SendMessageInput!) } If you are not using vue-cli-plugin-apollo (v0.20.0+), you need to configure vue-loader to transpile the string template tag. The main function to carry out a mutation with vue-apollo is the, wait for it, the mutation function. }. Simpler way of managing our queries in a more intuitive manner: But the UI doesn't know that a new todo has been added. This version requires Vue 2.6+ with serverPrefetch support. sendMessage (text: $text, subject: $subject) { Otherwise, you need to tell Apollo Client how to update the cache with the mutation result. When your component renders, useMutationreturns a tuple that includes: 1. After installing vue-apollo in your app, all your components can now use Apollo through the apollo special option.

We will use the Apollo client mutation method $apollo.mutate from vue-apollo as an example to insert new data and update cache locally using readQuery and writeQuery. In this example, if we already loaded the list of messages containing the one with id equals to abc, the mutation will search the cache for it and update its text field automatically. Almost two years ago I started my dev.to journey with the article about unit testing Vue + Apollo combination.During this time I had multiple requests about mocking an Apollo client and including it to the equation - just like React does with @apollo/react-testing library. Last time, I wrote a simple Vue application using dummy data in our components.Today, we’re going to link it to the Apollo GraphQL API that I wrote earlier. Each query in apollo object becomes a smart query and it will be executed automatically when the component is mounted. id This is really handy, especially after a mutation was performed, since this allows you to determine precisely how you want the cache to be updated.
