## Build

Build echarts source code:

Execute the instructions in the root directory of the echarts:
([Node.js](https://nodejs.org) is required)

```shell
# Install the dependencies from NPM:
npm install

# If intending to build and get all types of the "production" files:
npm run release
# The same as `node build/build.js --release`

# If only intending to get `dist/echarts.js`, which is usually
# enough in dev or running the tests:
npm run build
# The same as `node build/build.js`

# Get the same "production" files as `node build/build.js`, while
# watching the editing of the source code. Usually used in dev.
npm run watch
# The same as `node build/build.js -w`

# Check the manual:
npm run help
# The same as `node build/build.js --help`
```

Then the "production" files are generated in the `dist` directory.
