Modern Haskell Webserver Boilerplate

Graphql API

morpheus-graphql (https://github.com/morpheusgraphql/morpheus-graphql)
Schema is in schema.graphql

  type User {
      id: Int!
      email: String!
      name: String!
      updatedAt: String!
      createdAt: String!
  }

  type Session {
      token: String!
      user: User!
  }

  type Query {
      login(email: String!, password: String!): Session!
      myUserInfo: User!
  }

  type Mutation {
      register(email: String!, password: String!, name: String!): Session!
      changePassword(oldPassword: String!, newPassword: String!): Boolean!
  }

Database:
- Postgresql + Opaleye
- Migration using dbmate (https://github.com/amacneil/dbmate)
- Pooling using Data.Pool

This boilerplate wires up:

Reading .env using envy
Database
Graphql API
Authorization using JWT
Monad transformers

Running

Feed in you database & secret in .env:

$ cp .env.default .env

DATABASE_URL="postgres://Dandoh:dandoh@127.0.0.1:5432/webhaskell?sslmode=disable"
JWT_SECRET="my_jwt_secret"

Migrations
```
$ dbmate up
```
- More uses refer https://github.com/amacneil/dbmate
Run webserver
```
$ stack run
```

Now GraphQL API is at http://localhost:8080/api

You can also access Graphql Playground at http://localhost:8080/graphiql

Playground

Running on Docker

Feed in you database & secret in .env:
```
$ cp .env.default .env
```
(Optional) Edit anything you need in the .env file
Create and start docker containers
```
$ docker-compose up
```
Now you can visit: http://localhost:8080/ in your local machine.
Migrations will automatically run, and you can run them manually anytime using
```
$ docker-compose up dbmate
```
Stack will restart whenever you change any .hs file, thanks to entr
