parch

Restify + Sequelize

Parch is a simple RESTful framework combining the power of restify for routing and sequelize ORM for dao access. Stop rewriting your server code and get parched.

** WIP: parch is very much still in beta so use at your own risk **

Installation

npm install --save parch

Usage

Application

For a full list of available options see below

const parch = require("parch");

// define your app
const parch = new parch.Application({
  server: {
    name: "my-app",
    certificate: "/path/to/my.crt",
    key: "/path/to/my.key",
    middlewares: [
      restify.bodyParser(),
      restify.queryParser(),
      myCustomMiddleware()
    ]
  },
  authentication: {
    secretKey: "ssshhh",
    unauthenticated: [/\/posts[\s\S]*/, "/users/resetPassword"]
  },
  controllers: {
    dir: path.resolve(__dirname, "controllers")
  },
  database: {
    connection: {
      username: "postgres",
      password: "postgres",
      database: "postgres",
      host:  "localhost",
      dialect: "postgres",
      logging: true
    },
    models: {
      dir: path.resolve(__dirname, "models")
    }
  }
});

// wire up your routes
parch.map(function () {
  this.resource("user");
  this.route("user/resetPassword", {
    using: "users:resetPassword", // controller:method
    method: "post" // request method
  });
});

parch.start(3000).then(() => {
  console.log("App listening.")
});

The above will create the following route mapping

POST   /users               => UserController.create
GET    /users               => UserController.index
GET    /users/:id           => UserController.show
PUT    /users/:id           => UserController.update
DELETE /users/:id           => UserController.destroy
POST   /users/resetPassword => UserController.resetPassword

Controller

const parch = require("parch");

class UserController extends parch.Controller {
  constructor(options) {
    super(options);
  }

  index(req, res, next) {
    this.findAll(req.query).then(records => {
      /**
       * {
       *   users: [{
       *   ...
       *   }]
       * }
       */
       res.send(this.statusCodes.SUCCESS, records);
    }).catch(next);
  }

  show(req, res, next) {
    this.findOne(req.params.id).then(record => {
      /**
       * {
       *   user: {
       *   ...
       *   }
       * }
       */
       res.send(this.statusCodes.SUCCESS, record);
    }).catch(next);
  }

  create(req, res, next) {
    this.createRecord(req.body.user).then(record => {
      /**
       * {
       *   user: {
       *   ...
       *   }
       * }
       */
       res.send(this.statusCodes.CREATED, record);
    }).catch(next);
  }

  update(req, res, next) {
    this.updateRecord(req.params.id, req.body).then(updatedRecord => {
      /**
       * {
       *   user: {
       *   ...
       *   }
       * }
       */
       res.send(this.statusCodes.SUCCESS, record);
    }).catch(next);
  }

  destroy(req, res, next) {
    this.destroyRecord(req.params.id).then(() => {
      res.send(this.statusCodes.NO_CONTENT);
    }).catch(next);
  }

  resetPassword(req, res, next) {
    this.findOne(req.params.id).then(record => {
      record.password = req.body.password;
      return record.save();
    }).then(record => {
      res.send(this.statusCodes.SUCCESS);
    }).catch(next);
  }
}

Model

Models are defined following the sequelize define, pattern.

lib/models/user.js

class UserModel extends parch.Model {
  constructor() {
    super();
  }

  define(DataTypes) {
    const user = {
      email: {
        type: DataTypes.STRING,
        validate: { isEmail: true }
      }
    };

    return user;
  }
}

Associations

parch loads associations of a record as an array of ids.

class UserController extends parch.Controller {
  constructor() {
    super();
  }

  show(req, res, next) {
    this.findOne(req.params.id).then(user => {
      /**
       *  {
       *    user: {
       *      firstName: "John",
       *      posts: [1, 2, 3]
       *    }
       *  }
       */
    });
  }
}

Authentication and Authorization

Authentication and authorization is handled using jwt, with more options coming in the future. To disable auth for specific routes, use the authentication.unauthenticated array. Empty by default, you can add an entire controller, or a controller's method.

const parch = new parch.Application({
  authentication: {
    unauthenticated: [/\/posts[\s\S]*/, "/users/resetPassword"]
  }
});
