([enisdenjo#86](https://github.com/CandisIO/graphql-sse/issues/86)) ([b37a6f9](b37a6f9)) ### Performance Improvements * **client:** Avoid recreating result variables when reading the response stream ([16f6a6c](16f6a6c)) ### BREAKING CHANGES * **handler:** The handler is now server agnostic and can run _anywhere_ - Core of `graphql-sse` is now server agnostic and as such offers a handler that implements a generic request/response model - Handler does not await for whole operation to complete anymore. Only the processing part (parsing, validating and executing) - GraphQL context is now typed - Hook arguments have been changed, they're not providing the Node native req/res anymore - they instead provide the generic request/response - `onSubscribe` hook can now return an execution result too (useful for caching for example) - Throwing in `onNext` and `onComplete` hooks will bubble the error to the returned iterator ### Migration Even though the core of graphql-sse is now completely server agnostic, there are adapters to ease the integration with existing solutions. Migrating is actually not a headache! Beware that the adapters **don't** handle internal errors, it's your responsibility to take care of that and behave accordingly. #### [`http`](https://nodejs.org/api/http.html) ```diff import http from 'http'; - import { createHandler } from 'graphql-sse'; + import { createHandler } from 'graphql-sse/lib/use/http'; // Create the GraphQL over SSE handler const handler = createHandler({ schema }); // Create an HTTP server using the handler on `/graphql/stream` const server = http.createServer((req, res) => { if (req.url.startsWith('/graphql/stream')) { return handler(req, res); } res.writeHead(404).end(); }); server.listen(4000); console.log('Listening to port 4000'); ``` #### [`http2`](https://nodejs.org/api/http2.html) ```diff import fs from 'fs'; import http2 from 'http2'; - import { createHandler } from 'graphql-sse'; + import { createHandler } from 'graphql-sse/lib/use/http2'; // Create the GraphQL over SSE handler const handler = createHandler({ schema }); // Create an HTTP server using the handler on `/graphql/stream` const server = http.createServer((req, res) => { if (req.url.startsWith('/graphql/stream')) { return handler(req, res); } res.writeHead(404).end(); }); server.listen(4000); console.log('Listening to port 4000'); ``` #### [`express`](https://expressjs.com/) ```diff import express from 'express'; // yarn add express - import { createHandler } from 'graphql-sse'; + import { createHandler } from 'graphql-sse/lib/use/express'; // Create the GraphQL over SSE handler const handler = createHandler({ schema }); // Create an express app const app = express(); // Serve all methods on `/graphql/stream` app.use('/graphql/stream', handler); server.listen(4000); console.log('Listening to port 4000'); ``` #### [`fastify`](https://www.fastify.io/) ```diff import Fastify from 'fastify'; // yarn add fastify - import { createHandler } from 'graphql-sse'; + import { createHandler } from 'graphql-sse/lib/use/fastify'; // Create the GraphQL over SSE handler const handler = createHandler({ schema }); // Create a fastify app const fastify = Fastify(); // Serve all methods on `/graphql/stream` fastify.all('/graphql/stream', handler); fastify.listen({ port: 4000 }); console.log('Listening to port 4000'); ```
