## 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

# Rebuild source code immediately in watch mode when changing the source code.
# It opens the `./test` directory, and you may open `-cases.html` to get the list
# of all test cases.
# If you wish to create a test case, run `npm run mktest:help` to learn more.
npm run dev

# Check the correctness of TypeScript code.
npm run checktype

# If intending to build and get all types of the "production" files:
npm run release
```

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