ng-Momentum

Momentum is an Angular Schematic developed by the Bottle Rocket Web Team to build best-in-class web applications faster.

Getting Started

For the initial scaffolding (required before anything else cause it sets everything where it needs to be).

cd to/wherever/you/are/putting/your/project
ng new my-momentum-project
cd my-momentum-project/
ng add ng-momentum

If you want to include PWA features we recommend then running the next line.

ng add @angular/pwa

Extra details below about each option.

Helpful Commands

To run the fun try these commands in your project.

Scaffold

For the initial scaffolding (required before anything else cause it sets everything where it needs to be).

ng g ng-momentum:scaffold --spec=false --force

Detailed description of options.

Option	Type	Description	Enums	Default
--spec	boolean	Do you want to have the tests generated for you?	true, false	true
--skipScripts	boolean	Do you want to have the additional (helpful) package scripts added for you?	true, false	true
--includePwa	boolean	Include PWA features?	true, false	true
--uiFramework	string	Which ui framework are you intending to use? This sets the default for future view templates.	material, bootstrap, basic	material

VO

For building a value object. You may want to do this, or let the other generators create objects as they see necessary and then your can just reference your value objects. Whatever, it's your application.

ng g ng-momentum:vo --name=shoes --obj="{\"laces\":\"boolean\", \"color\":\"string\", \"size\":\"number\"}"

Detailed description of options.

--obj	string	Object string for the value object. (in JSON.stringify format).		{"id":"number", "title":"string"}
--flat	boolean	Flag to indicate if a dir is created.	true, false	false
--spec	boolean	Specifies if a spec file is generated.	true, false	true

View

This builds a view for you with the ui framework you previously set. You have a lot of options and this should he you get right to the important coding faster.

Service

This builds a service for you to help you make calls to outside locations.

ng g ng-momentum:svc --name=your-service

Detailed description of options.

Option	Type	Description	Enums	Default
--project	string	The name of the project.		default project
--path	string	The path to create the service within the service/ folder.		(none)
--name	string	Specifies the name of the value object.		(first argument)
--obj	string	Object string for the value object. (in JSON.stringify format).		{"id":"number", "title":"string"}

--uri	string	Specifies the service uri to hit.		(none)
--endpoint	string	Specifies the service endpoint to hit.		(none)
--operations	string	Specifies the service strategy (clrud).		clrud

Model

This builds either a basic model, a list model, or a 'selected object' model for you. Selected object models can load the model, create/update/save, and delete. Models are helpful if you have multiple components that are disconnected but need to share data/state. This can also be used to cache your data and have more control. You may not find them helpful at all though. So it is up to you.

ng g ng-momentum:model --name=heros --template=list

CRUD

This is the big one. You can just point this to an endpoint or state the object structure and it creates a full CRUD operation against your endpoint create for consumption. It's really cool.

Important Notes

Required updates

To fix the material issue https://github.com/angular/material2/pull/12028/commits/735c15b539671a4651aa75fc432b13b3499509a9

Yarn vs NPM

I've noticed that when using npm install there seems to be conflicts around @angular/core. These conflicts do not exist when using yarn. I would recommend using yarn vs npm install. By default schematics calls npm install initially. I just have been deleting the /node_modules folder and running yarn for a successful first build.

Todo

List of TODO items that are outstanding.

• view - add e2e tests
• crud - add e2e tests

Development

Testing

To test locally, install @angular-devkit/schematics globally and use the schematics command line tool. That tool acts the same as the generate command of the Angular CLI, but also has a debug mode.

Check the documentation with

schematics --help

Unit Testing

npm run test will run the unit tests, using Jasmine as a runner and test framework.

Publishing

To publish, simply do:

npm run build
npm publish

That's it!
