​
Install the Nango CLI

Install the Nango CLI globally:

npm install nango -g

In the folder where you want your integration folder (e.g. root of your project), run:

nango init nango-integrations

This creates the ./nango-integrations folder with some initial configuration and an example sync script. The nango-integrations directory looks like this:

nango-integrations/
├── .env
├── nango.yaml
├── models.ts
└── demo-github-integration # this is the integration unique ID and must match the nango.yaml entry and the integration ID in the UI
    └── syncs/
        └── github-issue-example.ts

​
CLI Authentication

Add the following env vars. We recommend that you have a .env file in ./nango-integrations:

NANGO_SECRET_KEY_PROD='<prod-secret-key>'
NANGO_SECRET_KEY_DEV='<dev-secret-key>'

Get your prod and dev secret keys from the Environment Settings tab (toggle between the prod and dev environment in the left nav bar).

For self-hosting, set the NANGO_HOSTPORT env variable to http://localhost:3003 (for local development) or your instance’s URL.
