Orillusion Contributing Guide

Hi! I'm really excited that you are interested in contributing to Orillusion. Before submitting your contribution, please make sure to take a moment and read through the following guidelines:

Issue Reporting Guidelines

  • Welcome to use Github to report a issues, request a feature, or ask a question

Pull Request Guidelines

  • Don't directly send PR to main branch, unless it's a urgent bug fix/patch.

  • Checkout a feature branch from a dev based branch, e.g. dev, and merge back against that branch.

  • Make sure to tick the "Allow edits from maintainers" box. This allows us to directly make minor edits / refactors and saves a lot of time.

  • If adding a new feature:

    • Add accompanying unit test or sample case.
    • Provide a convincing reason to add this feature. Ideally, you should open a suggestion issue first and have it approved before working on it.

  • If fixing a bug:

    • If you are resolving a special issue, add (fix #xxxx[,#xxxx]) (#xxxx is the issue id) in your PR title for a better release log, e.g. update entities encoding/decoding (fix #3899).
    • Provide a detailed description of the bug in the PR. Live sample/demo preferred.

  • It's OK to have multiple small commits as you work on the PR - GitHub can automatically squash them before merging.

  • Make sure CI tests pass!

  • Commit messages must follow the commit message convention so that changelogs can be automatically generated.

Development Setup

Node.js version 16+, and PNPM version 7+ is perferred.

First, you need to clone/flok repo:

$ git clone [email protected]:Orillusion/orillusion.git
$ cd orillusion
$ git checkout dev # `dev` branch is perfered to start your development

If you need to run samples, you may need to init the assets submodule to load models, images and other resources:

$ git submodule update --init # init /public assets folder, it may take a long time due to large file size

After cloning the repo, run:

$ pnpm i # install dev and optional deps of the project
$ pnpn i --no-optional # skip optional deps, install dev deps only if you don't need run ci tests

A high level overview of main tools used:

Scripts

Start a Dev server

After install all dependenceies of the project, just run pnpm run dev to boot up a dev environment locally, with live relaod of the soure code.

$ pnpm run dev

After executing the above command, visit http://localhost:3000 and try live samples from /samples

Build production libs

To build a production package:

$ pnpm run build

After executing the above command, the production libs (orillusion.es.js and orillusion.umd.js) will be generated in dist folder, along with all types *.d.ts in dist/src subfolder.

Unit Test

To start an auto unit tests:

$ pnpm run test

This will start an electron window to run all tests in test folder.

If you need to test in a docker/linux enviroment without GPU drivers:

$ pnpm run test:ci

This will force Electron to use a CPU based software Vulkan driver to process all tests with WebGPU APIs

API docs

To generate API docs:

$ pnpm run docs # generate all docs, including core and packages
$ pnpm run docs:core # core docs only

All md docs will be generated in docs folder.
