The repository is set up as an Angular project generated using ng-cli, which contains both the slider component, and a demo app.
The slider library is exported to an NPM package using ng-packagr, while the demo app is built and published to Github Pages.
The project relies on some auto-generated code using a number of scripts in scripts/ directory. To ensure that everything works as expected, you should always use npm run commands as described below. Using ng commands directly might not always work.
To build the ngx-slider library (NPM package), use:
npm run build:lib
The ngx-slider NPM package files will be generated in dist/ folder.
To build and run the demo app, use:
npm run start
The demo app should build and start on default URL http://localhost:4200.
To run unit tests, use:
npm run test
To run e2e tests, use:
npm run e2e
To run tslint, use:
npm run lint
Note: Currently (v1.2.1) most functionality is tested with e2e tests. This is not ideal for development, as running through the whole suite takes quite a long time. The plan for the future is to add more unit tests, so that development is easier.
The project is also set up to use Travis CI, which runs the script:
npm run ci
This is a shorthand for running unit tests, e2e tests, building the project with production config and running tslint.
As of v1.2.1, there are three main code generation scripts.
This script prepares some files like package.json and README.md for the slider library, based on files in top-level directory.
Note that the generated package.json for the library will be different from top-level package.json. This is because the top-level package.json is used to build and run the demo app, while the library package.json is specifically crafted for use with ng-packagr to build the library and later being included in the resulting NPM package.
This script prepares the demo snippets shown in demo app by pasting code from the samples and generating the HTML templates used in final app. Code highlighting is achieved using prismjs.
This script generates the API documentation pages in demo app. This is done by running typedoc and doing a bit of work to get the resulting HTML files in shape to be included as Angular components in the demo app. This is a bit hacky at the moment, as this is not a usual use-case for typedoc, but it works for now.
