# Connect to a Private npm Repository

Typically javascript/typescript based tests will include their dependencies in the `package.json`. If these libraries are hosted in publicly available repositories, Testery will just download them and install them prior to running your tests. But sometimes, you may want to have a privately hosted module (e.g. one that contains wrappers for your business objects).

To connect to a private npm repository, you will want to include the connection info in an `.npmrc` file or simply by adding your npm token as an environment variable.

Click Environments -> Add New Environment (or edit existing).

Under Files click Add File. Call the file `npmrc` and add the following content,

```
//registry.npmjs.org/:_authToken={{INSERT YOUR TOKEN HERE}}
```

The contents of this file will be encrypted on Testery.

When you run tests, the `npmrc` file will be created prior to running `npm install` and give the test runner access to your private npm repository.
