  1. Clone the repo into a public GitHub repository (or fork https://github.com/calcom/cal.com/fork). If you plan to distribute the code, keep the source code public to comply with AGPLv3. To clone in a private repository, acquire a commercial license

    git clone https://github.com/calcom/cal.com.git

    If you are on Windows, run the following command on gitbash with admin privileges:
    > git clone -c core.symlinks=true https://github.com/calcom/cal.com.git
    See docs for more details.

  2. Go to the project folder

    cd cal.com

  3. Install packages with yarn

    yarn

  4. 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 32 to generate a key and add it under CALENDSO_ENCRYPTION_KEY in the .env file.

  5. 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.

  6. Edit some TS in packages, and this messages shows often.

Solution

# Increase nodejs memory limit
export NODE_OPTIONS="--max-old-space-size=4096"

You can place this in your shell config like ~/.zshrc to run each startup.
