Installation

Run the following command in your terminal to install the latest version of hook and hook-cli:

curl -sSL https://raw.githubusercontent.com/doubleleft/hook/master/scripts/install.sh | bash

Local development server

To run a local development server, cd into hook directory, then run the server command:

$ cd ~/Projects/hook
$ hook server
...
PHP 5.4.33 Development Server started at Sat Apr 11 18:51:47 2015
Listening on http://0.0.0.0:4665
Document root is /Users/endel/Projects/hook/public
Press Ctrl-C to quit.

The default endpoint for local development server is http://0.0.0.0:4665.

Creating a new application

The first step to develop application with hook, is to create a new application in the server.

Deploying your application

The deploy command will upload all your application modifications inside hook-ext directory, such as modules (observers, routes, templates and channels), configurations (config.yaml, security.yaml, schema.yaml), packages (packages.yaml) and schedule (schedule.yaml).

hook deploy
...
Successfully deployed.

Every change you make inside hook-ext directory needs to be deployed to affect the backend.

Seeding collections

Collection seeding is a way to define some initial contents for your application's collections, such as categories, tags, etc. In this example we'll generate some dummy content for a collection called events.

To generate the seed file for the collection you need, run the following command:

hook generate:seed events
Seed created at 'hook-ext/seeds/events.yaml'.

You can now edit the hook-ext/seeds/events.yaml file that was generated to add your entries.

#
# Seed for events
#
truncate: true
data:
  - name: My first event
    picture: !upload path/to/picture.jpg
  - name: My second event
    picture: !upload path/to/picture-2.jpg

Things to note here:

You may upload files by using !upload instruction.
By using truncate: true instruction, the collection will be entirely cleared before being seeded again.

After you're done, let's seed the events collection with the following command:

hook db:seed events

If you have more than one seed file, you may seed all of them once by running:

hook db:seed

Be careful to not truncate collections with user generated content.

Interactive console

The interactive console is a tool to use the javascript interface with the CLI application key interactively from your terminal.

It is designed for testing and debugging your application code and evaluating state.

$ hook console

The console can be closed by pressing Ctrl+C twice.

The console has the JavaScript client instantiated by default as hook. Unlike the browser environment, every time the client tries to return a Promise, it will immediatelly be evaluated and its output will formatted and displayed.

Example:

client: javascript> hook.collection('events').count()
2

The console JavaScript client also has extended permissions on hook's restricted collections:

client: javascript>  hook.collection('auths').select('email').get()
...
