 [JointJS](https://jointjs.com) is a tested and proven  *JavaScript*/*Typescript* diagramming library that helps developers and companies of any size build visual and No-Code/Low-Code applications faster and with confidence. It’s a flexible tool from which a wide range of UIs can be created (interactive diagramming applications, drawing tools, data visualizations, UIs for monitoring systems, and many more). It can become the foundational layer of your next application and help you bring your idea to market in days, not months or years.

## Development Environment

If you want to work on *JointJS* locally, use the following guidelines to get started.

### Dependencies

Make sure you have the following dependencies installed on your system:
* [Node.js](https://nodejs.org/)
* [grunt-cli](http://gruntjs.com/using-the-cli)
* git

### Setup

Clone this git repository:
```
git clone https://github.com/clientIO/joint.git
```

Change into the joint directory:
```
cd joint
```

Install all NPM dependencies:
```
npm install
```

Generate build files from the source code:
```
grunt install
```

You are ready now to browse our demos:
```
cd demo
```

### Tests

To run all tests:
```
grunt test
```

To run only the server-side tests:
```
grunt test:server
```

To run only the client-side tests:
```
grunt test:client
```


### Lint

To check for linting errors in `src` and `types` directories:

```
npm run lint
```

To auto fix errors, run eslint for `src` and `types` directories:

```
npm run lint:fix
```

### Code Coverage Reports

To output a code coverage report in HTML:
```
grunt test:coverage
```

To output a code coverage report in [lcov format](http://ltp.sourceforge.net/coverage/lcov/geninfo.1.php):
```
grunt test:coverage --reporter="lcov"
```

The output for all unit tests will be saved in the `coverage` directory.


### Building Distribution Files

The `dist` directory contains pre-built distribution files. To re-build them, run the following:
```
grunt dist
```


## Documentation

The source for the *JointJS* documentation (plus *Geometry* and *Vectorizer* libraries) are included in this repository; see the `docs` directory. The documentation can be built into stand-alone HTML documents like this:
```
grunt build:docs
```
The output of the above command can be found at `build/docs`.
