MAS-FPA

Getting Started

1. After cloning / pulling the repo, make sure to run an npm install in the main directory
2. Create a .env file in the root directory with the following fields:

mongoURI=mongodb+srv://<username>:<password>@<mongodb-cluster-id>.mongodb.net/<database_name>?retryWrites=true&w=majority
jwtSecret=<some_jwt_secret>

Note: you can get the above mongoURI inside MongoDB Atlas dashboard. Navigate to your database and click on "connect." This should give you your mongoURI, from which you only need to paste in your password in the field <password>.

Also, the jwtSecret can be literally anything. Just keep it secret.

3. cd into client directory and run npm install --global expo-cli
4. Run npm install in the client folder to install the dependencies

For development, run npm run dev inside the root directory. Download the Expo Go app, create an account and scan the QR code in your terminal.

Making Requests to the API

To interact with todos in the database, you can make requests to this API. For these examples, I will use the hostname localhost, as this is what you will use when testing this locally. In production, replace this with your domain/hostname.

I suggest using Postman or Insomnia. If you use Insomnia, I have included the collection in server/MAS-FPA.json. You can import the collection into Insomnia by going to Preferences > Data > Import Data > From File and select MAS-FPA.json.
