Cookies

An HTTP cookie is a small piece of data that holds an information to let the server recognize the client. You can learn more about the cookies here.

There is a whatwg-node plugin to handle cookies using the web standard CookieStore. So it allows you to get cookies from the client’s request and set cookies back to the client in the response

You can learn more about the CookieStore API here in the MDN documentation.

Installation

npm i @whatwg-node/server-plugin-cookies

Usage

cookies.ts

import { createSchema, createYoga } from 'graphql-yoga'
import { useCookies } from '@whatwg-node/server-plugin-cookies'
 
const yoga = createYoga({
  schema: createSchema({
    typeDefs: /* GraphQL */ `
      type Query {
        cookie(name: String): String
      }
      type Mutation {
        setCookie(name: String, value: String): String
      }
    `,
    resolvers: {
      Query: {
        async cookie(root, args, ctx: YogaInitialContext) {
          const cookie = await ctx.request.cookieStore?.get(args.name)
          return cookie?.value
        }
      },
      Mutation: {
        async setCookie(root, args, ctx: YogaInitialContext) {
          await ctx.request.cookieStore?.set(args.name, args.value)
          return args.value
        }
      }
    }
  }),
  plugins: [useCookies()]
})
 
const server = createServer(yoga)
server.listen(4000, () => {
  console.log('Server is running on http://localhost:4000')
