# Topcoder React Utils
The [Topcoder](https://www.topcoder.com) collection of generic ReactJS
configurations, components and utilities to be shared between all internal and
external ReactJS projects developed by the Topcoder community.

## Installation
Install the package as
```bash
$ npm install --save topcoder-react-utils
$ ./node_modules/.bin/topcoder-lib-setup
```
Then import the global stylesheet into the root ReactJS component of your app:
```jsx
/* eslint-disable global-require */
if (process.env.NODE_ENV === 'production') {
  require('topcoder-react-utils/dist/prod/style.css');
} else {
  require('topcoder-react-utils/dist/dev/style.css');
}
/* eslint-enable global-require */
```

To upgrade this library to the latest version just execute again
```bash
$ ./node_modules/.bin/topcoder-lib-setup
```

## Development
For convenient development you can link this package into your host package:
1.  Clone [`topcoder-react-utils`](https://github.com/topcoder-platform/topcoder-react-utils)
    to your machine, and checkout the branch you are going to work with;
2.  Inside `topcoder-react-utils` folder:
    - Install dependencies with `$ npm install`;
    - Locate `node_modules/extract-css-chunks-webpack-plugin/index.js` and
      inside the `isChunk(..)` function (line #358) add `return true;` statement,
      so that this function always returns *true*. This step is necessary at
      the moment, because the check `chunk instanceof Chunk` check inside this
      function does not work as expected when Webpack config is spread across
      multiple inter-linked packages.
    - Run the dev build `$ npm run build:dev`. It will compile the package, and
      also will watch for the file changes to automatically re-compile it as
      necessary.
3.  Inside the host package execute
    `$ npm link PATH_TO_TOPCODER_REACT_UTILS_FOLDER`. It will create a symlink
    from `HOST_PACKAGE/node_modules/topcoder-react-utils` to your local copy of
    the `topcoder-react-utils` package, so that any changes you do there become
    automatically available to the host package.

CI/CD is set up with CircleCI 2.0 for this repo. A commit to any branch, beside
`master` will trigger testing of the commited code (it will run `$ npm test` and
ensures that it does not fail). A commit to the protected `master` branch (only
organization members and repo admins can commit to `master`) will trigger the
testing, and, if successful, release of the updated package to the NPM registry.

For successful release to NPM you should bump the package version in the
`package.json`. To do it conveniently you can use `$ npm version UPDATE_TYPE`
command, where `UPDATE_TYPE` stays for one of `patch`/`minor`/`major` to bump up
`2`, `1`, or `0` in a sample version number `v0.1.2`. This command will update
`package.json` and `package-lock.json`, and create a new commit and tag in the
checked-out Git branch. Mind that `patch` updates should not introduce
any breaking changes into the codebase! Breaking changes should be done via
`minor` or `major` update, and they should be documented in
the [CHANGELOG](CHANGELOG.md).
