Core Bugs (Login, Booking page, Emails are not working)

Developing

The development branch is main. This is the branch that all pull requests should be made against. The changes on the main branch are tagged into a release monthly.

To develop locally:

1. Fork this repository to your own GitHub account and then clone it to your local device.

2. Create a new branch:

   git checkout -b MY_BRANCH_NAME
   

3. Install yarn:

   npm install -g yarn
   

4. Install the dependencies with:

   yarn
   

5. Set up your .env file:

   • Duplicate .env.example to .env.
   • Use openssl rand -base64 32 to generate a key and add it under NEXTAUTH_SECRET in the .env file.
   • Use openssl rand -base64 24 to generate a key and add it under CALENDSO_ENCRYPTION_KEY in the .env file.

6. Setup Node If your Node version does not meet the project's requirements as instructed by the docs, "nvm" (Node Version Manager) allows using Node at the version required by the project:

   nvm use
   

   You first might need to install the specific version and then use it:

   nvm install && nvm use
   

   You can install nvm from here.

7. Start developing and watch for code changes:

   yarn dev
   

Building

You can build the project with:

yarn build

Please be sure that you can make a full production build before pushing code.
