Installation

1. Replace the mock data in data.json with your data.
2. Run npm i.
3. Start index.js.

Behaviour

1. A user accesses the /api path of the app. (for example http://localhost:8080/api)
2. The app sends the data from data.json to the user in JSON format.

Usage Ideas

• Check for a key or authentication password in the parameters of the url to limit access to the API.
• Add more paths based on your needs. (Might need to move the route handling (router.get) to separate files or folders)
• Add more JSON files based on your needs, or store data in variables as needed.

Tip
