| # React.js Koans | |
| If you want to learn React.js you came to the right place. We prepared a set of practical exercises that will help you learn React.js from square one. The only thing you need to know is JavaScript. Here we are using [ECMAScript 2015 standard](https://babeljs.io/docs/learn-es2015/). | |
| The Koans are a set of tasks to complete. Prepared tests checks if they are done correctly. | |
| ## Installation | |
| Make sure you have Node.js and Python 2 installed. | |
| 1. `git clone https://github.com/arkency/reactjs_koans.git` | |
| 2. `cd reactjs_koans` | |
| 3. `npm run setup` | |
| ## Koans structure | |
| * Edit the files found in the **`exercises`** directory. | |
| * The `koans` directory contains the source of all the exercises. `test` contains the tests. | |
| * `src` contains files compiled from `exercises`. | |
| * `build` contains sources launched in the web browser version of Koans. | |
| ## Start a local web server (optional) | |
| You can run a webserver and see your changes live in your web browser: | |
| 1. Run command `npm run start` | |
| 2. Visit http://localhost:8080/ | |
| ## Instructions | |
| 1. Remember about running the setup script before you start working on Koans! | |
| 2. Work on the code found in the `exercises` directory and run the tests to see if you did everything right. | |
| 3. You need to do the exercises in the given order. | |
| 4. Try to not peek at the test files! They contain spoilers. | |
| 5. To run the tests, use `npm run test`. To automatically run tests when your code changes, use `npm run watch`. | |
