Environment Variables

You'll need to create a local .env file to store your application's secret. Follow these steps to generate and store the secrets.

0. Create a COUCH_URL environment variable: Using Cloudant for example or a local instance of CouchDB, create an API key for the database. Store the key and password within your .env file. Use the key and password to create an environment variable named COUCH_URL using this pattern COUCH_URL=https://<key>:<password>@<your base url>/.

Example

COUCH_URL=https://sdfrtrerdfsxdnorth:187254aff7762f28afxu92d137c1899c14f7c999@jeffjohnson.cloudant.com/

0. Create a PORT environment variable used by the client application to connect and communicate with your api.

Example

PORT=4000

0. Create a COUCH_DATABASE environment variable. The name of the database.

Example

COUCH_DATABASE=library

Starting the api

Run the following command to start the api on localhost:4000.
