# Dependencies

## Fixed Dependencies

The dependencies available on the free plan are fixed, but they should cover most major use cases.

For cases where custom dependencies are required, upgrade to a paid plan.

### Major Dependencies

* mocha - [NPM](http://npmjs.com/package/mocha) - [Docs](https://mochajs.org/)
* chai - [NPM](https://www.npmjs.com/package/chai) - [Docs](https://www.chaijs.com/)
* sinon - [NPM](https://www.npmjs.com/package/sinon) - [Docs](https://sinonjs.org/)
* axios - [NPM](https://www.npmjs.com/package/axios) - [Docs](https://www.npmjs.com/package/axios)
* lodash - [NPM](https://www.npmjs.com/package/lodash) - [Docs](https://lodash.com/)

}
```

## Custom Dependencies

For paid plans, custom dependencies are an option.

To use custom dependencies, just change the "dependencies" entry in your [`routine.json`](/reference/routine-json.md) to "custom", as shown below.

```javascript
{
  "id": "rt-GKgRG",
  "projectId": "p-1HLbs9Z",
  "name": "custom-dep-tests",
  "description": "Tests with Custom Dependencies",
  "interval": {
    "unit": "min",
    "value": 10
  },
  "dependencies": "custom", // The "custom" option is available on paid plans
  "mocha": {
    "files": [
      "**/*.asrtd.js"
    ],
    "ignore": [],
    "bail": false,
    "ui": "bdd"
  },
  "timeoutSec": 10
}
```

Once that change is made, any subsequent pushes will include all of the dependencies listed in the "dependencies" entry of your `package.json`. "devDependencies" and "peerDependencies" are ignored.

A modified version of [`npm-shrinkwrap`](https://docs.npmjs.com/cli/shrinkwrap) is used to capture the exact versions of the dependencies in your current `node_modules` folder during the push.
