The Angular-Opium generator

A Yeoman generator for AngularJS and Opium.

Opium is an OCaml-based micro-framework. For AngularJS integration with other micro-frameworks, see https://github.com/rayokota/MicroFrameworkRosettaStone.

Installation

Install Git, node.js, and OPAM. The development mode also requires SQLite.

Install Yeoman:

npm install -g yo

Install the Angular-Opium generator:

npm install -g generator-angular-opium

The above prerequisites can be installed to a VM using the Angular-Opium provisioner.

Creating an Opium service

In a new directory, generate the service:

yo angular-opium

Install dependencies (Mirage ORM and Opium).

opam install orm opium

Build the service:

corebuild -pkg opium,cow.syntax,orm.syntax main.native

Run the service:

./main.native

Your service will run at http://localhost:3000.

Creating a persistent entity

Generate the entity:

yo angular-opium:entity [myentity]

You will be asked to specify attributes for the entity, where each attribute has the following:

• a name
• a type (String, Integer, Float, Boolean, Date, Enum)
• for a String attribute, an optional minimum and maximum length
• for a numeric attribute, an optional minimum and maximum value
• for a Date attribute, an optional constraint to either past values or future values
• for an Enum attribute, a list of enumerated values
• whether the attribute is required

Files that are regenerated will appear as conflicts. Allow the generator to overwrite these files as long as no custom changes have been made.

Build the service:

corebuild -pkg opium,cow.syntax,orm.syntax main.native

Run the service:

./main.native

A client-side AngularJS application will now be available by running

grunt server

The Grunt server will run at http://localhost:9000. It will proxy REST requests to the Opium service running at http://localhost:3000.

At this point you should be able to navigate to a page to manage your persistent entities.

The Grunt server supports hot reloading of client-side HTML/CSS/Javascript file changes.
