More examples

[MichalLytek]

• integration with apollo-engine (apollo-cache-control)
• usage with mongoose (typegoose)
• usage on client side (Apollo client state)
• using class mixins
• GraphQL Modules
• Join Monster
• graphql-shield integration
• using relations betweens types (user -> recipes -> comments)
• testing examples (unit and e2e)
• AWS lambda (apollo-server-lambda)
• sample fullstack project with React and Apollo

Please add some examples with apollo-server package. especially apollo-server-express and apollo-server-lambda

[MichalLytek]

Usage of apollo-server-express is the same as in its repository readme:

import express from 'express';
import bodyParser from 'body-parser';
import { graphqlExpress, graphiqlExpress } from 'apollo-server-express';
import { buildSchema } from "type-graphql";

async function bootstrap() {
  // the only different part
  const myGraphQLSchema = await buildSchema({
    resolvers: [__dirname + "/**/*.resolver.ts"],
  });
  const PORT = 3000;

  const app = express();

  // bodyParser is needed just for POST.
  app.use('/graphql', bodyParser.json(), graphqlExpress({ schema: myGraphQLSchema }));
  app.get('/graphiql', graphiqlExpress({ endpointURL: '/graphql' })); // if you want GraphiQL enabled

  app.listen(PORT);
}

bootstrap();

apollo-server-lambda usage looks the same as the only demand is to provide schema myGraphQLSchema = require('./schema'); so you might need to use buildSchemaSync function. However it's more complicated so I will try create an AWS free tier and try the lambda 😉

@19majkel94 thank you it works. This is just brilliant. I actually have found a way to integrate with injection-js as well. Hope this will be released soon. Actually you don't need to create an aws account. You can try it with serverless framework and serverless-offline plugin to emulate lambda environment at your local machine.

Is there any code samples for e2e tests?

[MichalLytek]

@codingmaven A lot of in tests folder 😄

const query = `{
  myQuery {
    myField
  }
}`;

const { data } = await graphql(schema, query);

expect(data!.myQuery.myField).toEqual("myFieldValue");

[RodolfoSilva]

@19majkel94 do you have any testing examples with typeorm?

[MichalLytek]

@RodolfoSilva Just use the dependency injection (TypeDI) and data mapper patter (repository) as in the typeorm-typegraphql examples here on repo. Then you can easily mock the object passed to the constructor in unit test to stub the DB access.

Hi there, would like to add +1 request to AWS Lambda example because it has been very annoying to set up this to work there.
I have this repository (https://github.com/ramonpm/typescript-serverless-graphql) running and working fine with serverless offline. However, once I deploy it to AWS lambda, I get this error

Unable to import module 'handler': Error
    at Function.Module._resolveFilename (module.js:547:15)
    at Function.Module._load (module.js:474:25)
    at Module.require (module.js:596:17)

    at Object.0 (/var/task/handler.js:29733:1)
    at __webpack_require__ (/var/task/handler.js:20:30)

Which is probably due to externals: [nodeExternals()], in my webpack.config.js but if I don't use that it fails badly with Error: Cannot use GraphQLSchema "[object GraphQLSchema]" from another module or realm
Thought about creating a new issue, but I noticed they have being closed pointing to this issue...

[visheshd]

@ramonpm here is a working version that I setup
https://github.com/causecode/type-graphql-typegoose-serverless

And another set of examples at https://github.com/kirill578/type-graphql-serverless-example

[ramonpm]

Thank you @visheshd
It turned out that for some reason I don't really care I had to use --useSeparateProcesses to run it locally without the conflicts. Should I care 😅 though ?

[omar-dulaimi]

Apollo server lambda is an example I would really appreciate seeing today.

[itpropro]

Can we add Azure Functions to that list @MichalLytek? I would be able to provide a working example the following days.
