# Electron Dev on Codespaces
|
|
|
|
Welcome to the Codespaces Electron Developer Environment.
|
|
|
|
## Quick Start
|
|
|
|
Upon creation of your codespace you should have [build tools](https://github.com/electron/build-tools) installed and an initialized gclient checkout of Electron. In order to build electron you'll need to run the following command.
|
|
|
|
```bash
|
|
e build
|
|
```
|
|
|
|
The initial build will take ~8 minutes. Incremental builds are substantially quicker. If you pull changes from upstream that touch either the `patches` folder or the `DEPS` folder you will have to run `e sync` in order to keep your checkout up to date.
|
|
|
|
## Directory Structure
|
|
|
|
Codespaces doesn't lean very well into gclient based checkouts, the directory structure is slightly strange. There are two locations for the `electron` checkout that both map to the same files under the hood.
|
|
|
|
```graphql
|
|
# Primary gclient checkout container
|
|
/workspaces/gclient/*
|
|
└─ src/* - # Chromium checkout
|
|
└─ electron - # Electron checkout
|
|
# Symlinked Electron checkout (identical to the above)
|
|
/workspaces/electron
|
|
```
|
|
|
|
## Goma
|
|
|
|
If you are a maintainer [with Goma access](../docs/development/goma.md) it should be automatically configured and authenticated when you spin up a new codespaces instance. You can validate this by checking `e d goma_auth info` or by checking that your build-tools configuration has a goma mode of `cluster`.
|
|
|
|
## Running Electron
|
|
|
|
You can run Electron in a few ways. If you just want to see if it launches:
|
|
|
|
```bash
|
|
# Enter an interactive JS prompt headlessly
|
|
xvfb-run e start -i
|
|
```
|
|
|
|
But if you want to actually see Electron you will need to use the built-in VNC capability. If you click "Ports" in codespaces and then open the `VNC web client` forwarded port you should see a web based VNC portal in your browser. When you are asked for a password use `builduser`.
|
|
|
|
Once in the VNC UI you can open `Applications -> System -> XTerm` which will open a VNC based terminal app and then you can run `e start` like normal and Electron will open in your VNC session.
|
|
|
|
## Running Tests
|
|
|
|
You run tests via build-tools and `xvfb`.
|
|
|
|
```bash
|
|
# Run all tests
|
|
xvfb-run e test
|
|
|
|
# Run the main process tests
|
|
xvfb-run e test --runners=main
|
|
|
|
# Run the old remote tests
|
|
xvfb-run e test --runners=remote
|
|
```
