Installation

umd

The UMD build is also available on unpkg.com:

<link rel="stylesheet" href="https://unpkg.com/@momentum-design/widgets/dist/widgets.css" />
<script src="https://unpkg.com/@momentum-design/widgets/dist/widgets.umd.js"></script>

Then you can find the library on window.mdw.

npm

NPM is the easiest and fastest way to get started using this library. It is also the recommended installation method when building single-page applications (SPAs). It pairs nicely with a CommonJS module bundler such as Webpack.

# latest stable
$ npm i @momentum-design/widgets

Use with Angular

1. Import library and enable web component support in src/app/app.module.ts.

   import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
   import { BrowserModule } from '@angular/platform-browser';
   +import '@momentum-design/widgets';
   
   import { AppComponent } from './app.component';
   
   @NgModule({
     declarations: [
       AppComponent,
     ],
     imports: [
       BrowserModule
     ],
     providers: [],
     bootstrap: [AppComponent],
   +  schemas: [CUSTOM_ELEMENTS_SCHEMA]
   })
   export class AppModule { }

2. Use the components in your HTML template.

   <mdw-chart
     type="pie"
     data='{
            "Alabama": 13,
            "Colorado": 17,
            "Arizona": 8,
            "Vermont": 10,
            "South Carolina": 40
          }'
   ></mdw-chart>

Contributing

Prerequisites

• Install Node.js which includes Node Package Manager. We recommend to use version 16 and above.

Steps to Start

1. Clone this repo.

2. Install all dependencies via run command npm run init.

3. Now, run npm start to start your work.

   • The component code should be placed to src/components. The new component should be structured as below:

     new-component
       ├─ index.ts                 // should export all public members
       ├─ new-component.ts         // the component code
       ├─ new-component.spec.ts    // unit tests
       ├─ new-component.types.ts   // all types definitions
       └─ new-component.plugins.ts // plugins of chart.js if need
     

   • The style file should be placed with component code and imported in src/styles/main.scss.

   • Also export the new component in src/components/index.ts file.

   • The internal folder dependency should be as below. That means we should not import anything from core folder into types folder or components into core folder.

     components ─⫸ core ─⫸ types
     

4. Commit your changes and push them to your forked repo, and submit a Pull Request to main branch.

The <type> and <summary> fields are mandatory, the (<scope>) field is optional.

Useful Commands

• npm run data will print the random data which is predefined in ./tools/data.ts and can be used to test your component. For example, npm run data -- --pie --default --5, npm run data -- --number --10 to get 10 random numbers.
