A modular AST-based GraphQL request execution interface.

A hypothetical Link setup

There are multiple ways to set up your link by using other links. Read more here.

Here's a simple example using Link.from:

import "package:gql_link/gql_link.dart";
import "package:gql_dedupe_link/gql_dedupe_link.dart";
import "package:gql_http_link/gql_http_link.dart";

import "./my_custom_link.dart";

void main () {
  final link = Link.from([
    MyCustomLink(),
    DedupeLink()
    HttpLink("/graphql"),
  ]);
}

To use a link to execute GraphQL operations, it must have been set up to end with a terminating link. In this case, it's HttpLink.

When your link is set up, your GraphQL operation must be wrapped in a Request and executed via link.request(request);

Links are designed to be composable. If you need to add a custom behavior, you can implement your own Link by extending the Link class. If you prefer functions over classes, you can use LinkFunction together with Link.function. If you have to route a request to some other links based on some set of conditions, Link.route(LinkRouter route) might be what you need.
