# Where to start?
Have a fix or a new feature? [Search for corresponding issues](https://github.com/algolia/docsearch/issues) first then create a new one.
# Development workflow
## Requirements
To run this project, you will need:
- Node.js >= v8.7.0, use nvm - [install instructions](https://github.com/creationix/nvm#install-script)
- [Ruby](https://www.ruby-lang.org/en/)
- [Bundler](http://bundler.io/)
## Launch
```sh
npm install
npm run dev:docs
```
Then go to:
- http://localhost:4000/docsearch/ documentation website with autoreload
- http://localhost:8080 local DocSearch example for easy hacking/additions/fixes
## Local build
You might want to expose a local build to the outside to test things on real
websites. To do so:
```sh
npm run serve
```
Then files will be available at http://localhost:8080. Use [ngrok](https://ngrok.com/download) to
then expose your build to the web.
# Commit message guidelines
We use [conventional changelog](https://github.com/ajoslin/conventional-changelog) to generate our changelog from our git commit messages.
Here are the rules to write commit messages, they are the same than [angular/angular.js](https://github.com/angular/angular.js/blob/7c792f4cc99515ac27ed317e0e35e40940b3a400/CONTRIBUTING.md#commit-message-format).
Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
format that includes a **type**, a **scope** and a **subject**:
```text
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
```
The **header** is mandatory and the **scope** of the header is optional.
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
to read on GitHub as well as in various git tools.
## Revert
If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
## Type
Must be one of the following:
* **feat**: A new feature
* **fix**: A bug fix
* **docs**: Documentation only changes
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing
semi-colons, etc)
* **refactor**: A code change that neither fixes a bug nor adds a feature
* **perf**: A code change that improves performance
* **test**: Adding missing tests
* **chore**: Changes to the build process or auxiliary tools and libraries such as documentation
generation
## Scope
The scope could be anything specifying place of the commit change. For example `RefinementList`,
`refinementList`, `rangeSlider`, `CI`, `url`, `build` etc...
## Subject
The subject contains succinct description of the change:
* use the imperative, present tense: "change" not "changed" nor "changes"
* don't capitalize first letter
* no dot (.) at the end
## Body
Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
The body should include the motivation for the change and contrast this with previous behavior.
## Footer
The footer should contain any information about **Breaking Changes** and is also the place to
reference GitHub issues that this commit **Closes**.
**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
# Releasing
If you are a maintainer, you can release.
We use [semver](http://semver-ftw.org/).
You must be on the master branch.
```sh
npm run release
```
