# Building Wave Terminal

These instructions are for setting up dependencies and building Wave Terminal from source on macOS, Linux, and Windows.

## Prerequisites

### OS-specific dependencies

#### macOS

You will need macOS 10.15 or later to build and run Wave.

macOS does not have any platform-specific dependencies.

#### Linux

Make sure you have a recent install of GCC and Zip.

Debian:

```sh
sudo apt install build-essential zip
```

Fedora:

```sh
sudo dnf install make automake gcc gcc-c++ kernel-devel
```

Arch:

```sh
sudo pacman -S base-devel
```

#### Windows

You will need a 64-bit, somewhat-recent version of Windows to build and run Wave (Windows 10 1809 or later).

You will need the GNU build toolchain installed in order for Go to work on Windows. In most cases, this requires installing MinGW-w64.

The easiest way to install this is using MSYS2: https://www.msys2.org/

If you prefer an alternative method, you can find other methods here: https://www.mingw-w64.org/downloads/

### Task

Download and install Task (to run the build commands): https://taskfile.dev/installation/

Task is a modern equivalent to GNU Make. We use it to coordinate our build steps. You can find our full Task configuration in [Taskfile.yml](Taskfile.yml).

### Go

Download and install Go via your package manager or directly from the website: https://go.dev/doc/install

### NodeJS

Make sure you have a recent version of NodeJS installed (>= 20).

See NodeJS's website for platform-specific instructions: https://nodejs.org/en/download

### Yarn Modern

Once you have NodeJS installed, you'll need to enable Corepack so that Yarn Modern can work:

```sh
corepack enable
```

If your NodeJS distribution does not ship with Corepack, you can install it manually using NPM:

```sh
npm install -g corepack
corepack enable
```

Corepack's official documentation says to uninstall Yarn and PnPM first, but this is probably overkill. If you have any issues, try removing them from your system before continuing.

For more information on Corepack, check out [this link](https://yarnpkg.com/corepack).

## Clone the Repo

```sh
git clone git@github.com:wavetermdev/waveterm.git
```

or

```sh
git clone https://github.com/wavetermdev/waveterm.git
```

## Build and Run

All the methods below will install Node and Go dependencies when they run the first time. All these should be run from within the Git repository.

### Development server

Run the following command to build the app and run it via Vite's development server (this enables Hot Module Reloading):

```sh
task electron:dev
```

### Standalone

Run the following command to build the app and run it standalone, without the development server. This will not reload on change:

```sh
task electron:start
```

### Packaged

Run the following command to generate a production build and package it. This lets you install the app locally. All artifacts will be placed in `make/`.

```sh
task package
```

## Debugging

### Frontend logs

You can use the regular Chrome DevTools to debug the frontend application. You can open the DevTools using the keyboard shortcut `Cmd+Option+I` on macOS or `Ctrl+Option+I` on Linux and Windows. Logs will be sent to the Console tab in DevTools.

### Backend logs

Backend logs for the development version of Wave can be found at `~/.waveterm-dev/waveapp.log`. Both the NodeJS backend from Electron and the main Go backend will log here.
