Building

This document alongside Releasing.md primarily cover our internal build process for release builds, if you are an external contributor please refer to Contributing.md for building instructions.

Automated

Automatic building of session binaries is done using github actions. Windows and linux binaries will build right out of the box but there are some extra steps needed for Mac OS

Mac OS

The build script for Mac OS requires you to have a valid Developer ID Application certificate. Without this the build script cannot sign and notarize the mac binary which is needed for Catalina 10.15 and above. If you would like to disable this then comment out "afterSign": "build/notarize.js", in package.json.

You will also need an App-specific password for the apple account you wish to notarize with

Setup

Once you have your Developer ID Application you need to export it into a .p12 file. Keep a note of the password used to encrypt this file as it will be needed later.

We need to Base64 encode this file, so run the following command:

base64 -i certificate.p12 -o encoded.txt

On GitHub:

  1. Navigate to the main page of the repository.
  2. Under your repository name, click Settings.
  3. In the left sidebar, click Secrets.
  4. Add the following secrets:
    1. Certificate
      • Name: MAC_CERTIFICATE
      • Value: The encoded Base64 certificate
    2. Certificate password
      • Name: MAC_CERTIFICATE_PASSWORD
      • Value: The password that was set when the certificate was exported.
    3. Apple ID
      • Name: SIGNING_APPLE_ID
      • Value: The apple id (email) to use for signing
    4. Apple Password
      • Name: SIGNING_APP_PASSWORD
      • Value: The app-specific password that was generated for the apple id
    5. Team ID (Optional)
      • Name: SIGNING_TEAM_ID
      • Value: The apple team id if you're sigining the application for a team

Manual

Node version

You will need node 18.15.0. This can be done by using nvm and running nvm use or you can install it manually. Once nvm is installed, just run nvm install to install the version from the .nvmrc file and then nvm use to use it.

Prerequisites

Linux

Here are the steps to build the app for Linux:

sudo apt-get install python2 git-lfs
git lfs install
# install nvm by following their github README
nvm install # install the current node version used in this project
nvm use # use the current node version used in this project
npm install -g yarn # install yarn globally for this node version
yarn install --frozen-lockfile # install all dependencies of this project
yarn build-everything # transpile and assemble files
yarn start-prod # start the app on production mode (currently this is the only one supported)
Windows

Building on windows should work straight out of the box, but if it fails then you will need to run the following:

npm install --global --production windows-build-tools@4.0.0
npm install --global node-gyp@latest
npm config set python python2.7
npm config set msvs_version 2015
Mac

If you are going (and only if) to distribute the binary then make sure you have a Developer ID Application certificate in your keychain.

You will also need to generate an app specific password for your Apple ID.

Then run the following to export the variables

export SIGNING_APPLE_ID=<your apple id>
export SIGNING_APP_PASSWORD=<your app specific password>
export SIGNING_TEAM_ID=<your team id if applicable>

Then, to just generate the files and build the app do

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash # install nvm


# the script above prints  at the end a few lines you have to run in your terminal

https://git-lfs.github.com/ # visit this page, download and install git-lfs

git lfs install # once git lfs is installed, you have to run this command too

nvm install # install the current node version used in this project
nvm use # use the current node version used in this project
npm install -g yarn # install yarn globally for this node version
yarn install --frozen-lockfile # install all dependencies of this project
yarn build-everything # transpile and assemble files
yarn start-prod # start the app on production mode (currently this is the only one supported)

Commands

The rpm package is required for running the build-release script. Run the appropriate command to install the rpm package:

sudo pacman -S rpm    # Arch
sudo apt install rpm  # Ubuntu/Debian

Run the following to build the binaries for your specific system OS.

npm install yarn --no-save
yarn install --frozen-lockfile
yarn build-everything
yarn build-release

The binaries will be placed inside the release/ folder.
