REST and GraphQL really aren't that different. I'll prove it!
GraphQLess is a thin wrapper around the official express-graphql project.
GraphQLess lets you write a GraphQL server in an Express.js style.

Setup

yarn add graphqless

And here is how you write a server... Look familiar?

const GraphQLess = require('graphqless');
const app = new GraphQLess();

const db = { users: [{ name: 'Tyler' }] };

app.get('/users', (req, res) => {
  const { users } = db;
  res.send(users);
});

app.get('/user', (req, res) => {
  const user = db.users.find(user => user.name === req.body.name);
  res.send(user);
});

app.post('/createUser', (req, res) => {
  const userCount = db.users.push({ name: req.body.name });
  res.send(userCount);
});

app.listen(3000, () => {
  console.log('Visit: http://localhost:3000/playground');
});

I know it looks like Express.js but the code above is a GraphQL server! There is one caveat though...

GraphQL requires us to write a schema that describes the .get and .post functions' inputs and outputs.

Just know that .get === Query && .post === Mutation. Now let's modify the last few lines of the snippet above to include the required schema:

app
  .useSchema(
    `
    type Query {
      users: [User]
      user(name: String): User
    }
    type Mutation {
      createUser(name: String): Int
    }
    type User {
      name: String
    }
  `
  )
  .listen(3000, () => {
    console.log('Visit: http://localhost:3000/playground');
  });

That's the only catch! You now have a fully functioning and extendable GraphQL server.

You can find more examples in the examples folder.
