The best integration of Apollo Server 4 for SvelteKit is a solution that allows users to utilize the advantages of Apollo Server to enhance the experience of their SvelteKit-based applications. Apollo Server is an open-source GraphQL server framework that makes it easy to define and expose GraphQL APIs, while SvelteKit is a toolkit for developing modern and dynamic web applications. By combining these two solutions, users can create web applications efficiently and smoothly.

To install this module, run the following command in your terminal:
npm install @apollo/server apollo-server4-sveltekit
o
yarn add @apollo/server apollo-server4-sveltekit
Before anything, you must create a file +server.ts
in the src/routes/api/
folder of your SvelteKit project.
To use this function, first import it in your code:
// src/routes/api/+server.ts
import { ApolloServer } from '@apollo/server'
import { createHandler } from 'apollo-server4-sveltekit'
then you can use the createHandler
function to create an Apollo Server handler:
const typeDefs = `
type Query {
ping: String
}
`
const resolvers = {
Query: {
ping: () => 'pong',
},
}
const server = new ApolloServer({
typeDefs,
resolvers,
})
const handler = createHandler(server, {
context: async (context) => ({ context }),
})
export const GET = handler
export const POST = handler
export const PUT = handler
export const PATCH = handler
export const DELETE = handler
The createHandler function takes as an argument an Apollo server and an optional options object with a context function. The context function will be executed for each request and should return an object with any necessary context information to process the request.
If you want to make more advanced configurations or see the difference of apollo server 4 with older versions, you can see the official Apollo Server documentation here.
