hapi-forest

hapi-forest

Provides REST handlers for mongoose models. Can also generate ready to use routes, for fast bootstrapping.

Quickstart

1. Install it

npm i --save hapi-forest # or yarn add hapi-forest if you prefer

1. Register the plugin.

// register hapi-forest
server.register({
  register: require('hapi-forest'),
  options: {
    // add your models here for auto route generation
    bootstrap: [ require('./models/user-model') ]
  }
});

1. Test your dynamically generated REST endpoints. hapi-swagger works nicely with hapi-forest.

Take a look at the example directory for a full example.

Plugin options

• bootstrap: [ MongooseModel, MongooseModel, … ]

  Will generate ready to use CRUD routes. hapi-forest will attempt to generate a basic joi schema based on the model.

Handlers

You can use the forest handler and define your own routes, instead of auto-generating them. This is useful if you need more control over your endpoints or want custom validation.

The forest handler behaves differently based on your route definition. GET, POST, PATCH & PUT are supported.

URL parameter

For routes like GET /collection/{name}, the first URL parameter (name in this case) is used as the "id". It will be used in the condition of the mongoose query.

{id} will translate to _id for convenience.

Generic Options for all methods

Option	Description
model	required – The mongoose Model for this route.
type	Overwrites the auto selected handler. Can be one of getOne, getAll, post, put, delete
preQuery	A Function that gets passed the current mongoose query, that was generated by forest.
transformResponse	A Function that gets passed the response. You have to return the modified response.

getOne

Returns all documents from the specified model.

• Only custom fields can be selected using select.
• the first parameter in the path (name in this example) will be used to query

server.route({
  method: 'GET',
  path: '/users/{name}',
  handler: {
    forest: {
      model: User,
    }
  }
});

getAll

Returns all documents from the specified model. The result will be streamed.

• Only custom fields can be selected using select.
• The filterByQuery option allows basic filtering of the results by sending a query with the request. (?group=nodejs&role=developer)
  • the query that results from the user input can be modified with the transformQuery option. You can specify a function that has to return the updated query.
• The allowLimit option gives the client the ability to limit the number of results by adding $limit=x to the query parameters.

server.route({
  method: 'GET',
  path: '/users',
  handler: {
    forest: {
      model: User,
      select: 'firstName group lastName birthday',
    }
  }
});

post

Creates a new document.

• skipMongooseHooks will use a faster mongoose create implementation, skipping all hooks.

server.route({
  method: 'POST',
  path: '/users',
  handler: {
    forest: {
      model: User
    }
  }
});

put

Updates an existing document or creates a new document if it does not exist. For now an update will not overwrite and existing document but only update it, like patch does.

• you can disallow creating new documents with allowUpsert: false. PUT will behave like PATCH in that case.

server.route({
  method: 'PUT',
  path: '/users/{name}',
  handler: {
    forest: {
      model: User,
      allowUpsert: true,
    }
  }
});

delete

Deletes a document.

• the first parameter in the path (name in this example) will be used to query

server.route({
  method: 'DELETE',
  path: '/users/{name}',
  handler: {
    forest: {
      model: User,
    }
  }
});
