# Contributing to speedscope
|
|
|
|
Hi! This is a short guide & set of guidelines for contributing to speedscope.
|
|
Contributors of all skill levels are welcome to submit pull requests.
|
|
|
|
This project adheres to the Contributor Covenant [code of conduct](./CODE_OF_CONDUCT.md).
|
|
All contributors are expected to uphold this code of conduct.
|
|
|
|
## Setting up for development
|
|
|
|
To start running speedscope locally, run the following:
|
|
|
|
git clone https://github.com/jlfwong/speedscope.git
|
|
cd speedscope
|
|
npm install
|
|
npm run serve
|
|
|
|
This should open up a running version of speedscope in your default browser.
|
|
|
|
In your terminal, you should see something like this:
|
|
|
|
$ npm run serve
|
|
> speedscope@0.7.1 serve /Users/jlfwong/code/speedscope
|
|
> parcel assets/index.html --open --no-autoinstall
|
|
|
|
Server running at http://localhost:1234
|
|
✨ Built in 7.30s.
|
|
|
|
Most of speedscope is written in TypeScript. If you're unfamiliar with
|
|
TypeScript, then you can either just try to learn it as you go, then the
|
|
[official TypeScript
|
|
documentation](https://www.typescriptlang.org/docs/home.html) may be of use
|
|
to you!
|
|
|
|
If you're not sure where the code you want to modify lives, the [`README.md`
|
|
in the `src/` directory](./src/README.md) might be helpful.
|
|
|
|
## Code formatting
|
|
|
|
All TypeScript code in speedscope is automatically formatted with
|
|
[Prettier](https://prettier.io/). This means that while you're writing your code,
|
|
you don't have to worry about following a formatting guide, because a program will
|
|
format your code for you!
|
|
|
|
The easiest way to use Prettier is via an editor integration. See the [Editor
|
|
Integration](https://prettier.io/docs/en/editors.html) page from Prettier's
|
|
documentation for help with that.
|
|
|
|
If you don't want to do that, you can alternatively run the autoformatter by
|
|
running `npm run prettier`.
|
|
|
|
## Running tests
|
|
|
|
All TypeScript tests are written use [Jest](https://jestjs.io/). To run the
|
|
tests, run `npm run jest`.
|
|
|
|
## Contributing new features
|
|
|
|
Before contributing code to implement a new feature, please open an issue to
|
|
discuss it first. Large pull requests that are submitted without first getting
|
|
maintainer buy-in are unlikely to be reviewed or merged.
|
|
|
|
For features that will cause a visual change, please include visual mockups of
|
|
the change you're planning on making.
|
|
|
|
## Contributing bug fixes
|
|
|
|
If you discover a bug, please file an issue. If the code change required to
|
|
fix it is small (< ~20 lines), then feel free to just open a PR to fix the
|
|
issue without trying to get buy-in ahead of time.
