Migration from Apollo Server#

Installation#

You can start with installing graphql-yoga package.

yarn add @graphql-yoga/node

pnpm add @graphql-yoga/node

npm install @graphql-yoga/node

Install equivalent Envelop plugins of the Apollo Server#

Some features that are included within apollo-server by default must be installed as envelop plugins (Learn more about envelop plugins here).

Apollo Federation
- If you are using Apollo Federation, install @envelop/use-apollo-federation
Apollo Server Errors
- If you are using Apollo Server errors, install @envelop/use-apollo-server-errors
Apollo Tracing
- If you are using Apollo Tracing, install @envelop/use-apollo-tracing
Response Cache
- If you are using Response Cache, you should set up @envelop/use-response-cache for the same functionality

Check out more plugins on Envelop Plugin Hub

Example initial usage of GraphQL Yoga#

For example if you are using Apollo Server Errors;

apollo-server-errors-example.ts

import { schema } from './schema'
- import { ApolloServer } from 'apollo-server'
+ import { createServer } from '@graphql-yoga/node'
+ import { useApolloServerErrors } from '@envelop/apollo-server-errors'

- const server = new ApolloServer({
+ const server = createServer({
  // You can also pass `typeDefs` and `resolvers` here directly if you previously use `ApolloServer` constructor to build your `GraphQLSchema`
  // schema: { typeDefs, resolvers },
  schema,
+  plugins: [useApolloServerErrors()],
})

server.start()

Migration from standalone `apollo-server`#

You don't need anything special. You can just use GraphQL Yoga as in the example above.

Migration from `apollo-server-*`#

Check the integration section to choose the server framework you are using with Apollo Server.

For example, if you are using Express, you should remove server.start() from the code above and replace server.applyMiddleware({ app }) with the route as in Express Integration section

- server.applyMiddleware({ app })
+ app.use('/graphql', server)
