Note: These files are conventionally not supposed to be committed to source code repository for security purposes. In production environment, these variables are set using the service used to deploy the app.

For both the backend and frontend, there are some values that need to be passed to the add as environment variables. This can be achieved by using a .env file for go backend and a .env.local file for next.js front-end.

Find the format of the files below. The app expects all the variables mentioned below.

Backend

Create .env file in the root / directory of the project with the following contents

MONGODB_URI=link to mongodb server

Note: for local server, this value is mostly mongodb://localhost:27017

Frontend

Create .env.local file in the /web directory of the project with the following contents

BACKEND_URI=...
NEXTAUTH_SECRET=...
GITHUB_ID=...
GITHUB_SECRET=...
GOOGLE_CLIENT_ID=...
GOOGLE_CLIENT_SECRET=...

Legend

  • BACKEND_URI is the link to the backend server. For local development, this project is configured to use http://localhost:3001

  • NEXTAUTH_SECRET is a randomly generated secret for NextAuthJS using

    openssl rand -base64 32

  • GITHUB_ID and GITHUB_SECRET are provided by GitHub after creating the oAuth app in Github

  • GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET are provided by Google after creating the oAuth app in Google
