Contributing to Leafpub

Thanks for your help in making Leafpub better. Before you submit an issue or pull request, please read through this document.

Following these guidelines helps to communicate that you respect the time of the developers managing and developing this open source project. In return, they should reciprocate that respect in addressing your issue or assessing patches and features.

Using the issue tracker

The issue tracker is the preferred channel for bug reports and submitting pull requests, but please respect the following restrictions:

  • Please do not use the issue tracker for personal support requests. The Leafpub Community Forum is a better place to get help.

  • Please do not derail or troll issues. Keep the discussion on topic and respect the opinions of others.

  • Please do not post comments consisting solely of "+1" or "👍". Use GitHub's "reactions" feature instead.

  • Please do not open issues or pull requests regarding bugs in third party libraries. Open them in their respective repositories.

Bug reports

A bug is a demonstrable problem that is caused by the code in the repository. Good bug reports are extremely helpful, so thanks!

Guidelines for bug reports:

  1. Validate and lint your code — to ensure your problem isn't caused by a simple error in your own code.

  2. Use the GitHub issue search — check if the issue has already been reported.

  3. Check if the issue has been fixed — try to reproduce it using the latest master or development branch in the repository.

  4. Isolate the problem — ideally create a reduced test case and a live example.

A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What steps will reproduce the issue? What browser(s) and OS experience the problem? Do other browsers show the bug differently? What would you expect to be the outcome? All these details will help people to fix any potential bugs.


Short and descriptive example bug report title

A summary of the issue and the browser/OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.

  1. This is the first step
  2. This is the second step
  3. Further steps, etc.

<url> - a link to the reduced test case

Any other information you want to share that is relevant to the issue being reported. This might include the lines of code that you have identified as causing the bug, and potential solutions (and your opinions on their merits).

Pull requests

Good pull requests — patches, improvements, new features — are a fantastic help. They should remain focused in scope and avoid containing unrelated commits.

Please ask first before embarking on any significant pull request (e.g. implementing features, refactoring code, porting to a different language), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.

Please adhere to the coding guidelines used throughout the project (indentation, accurate comments, etc.) and any other requirements.

Do not edit CSS and JS files in app/src/admin! Those files are automatically generated. You should edit the source files in scripts and styles instead.

Adhering to the following process is the best way to get your work included in the project:


With Leafpub 1.2 all language files are located in their own GitHub repo. This decision was made to update the language files independently from the Leafpub core files. With the update functionality introduced wiht Leafpub 1.2 it's possible to update the language files individually.

Leafpub has been translated to the following languages so far:

Language Repo
Danish translation (da-dk)
German translation (de-de)
Spanish translation (es)
French translation (fr-fr)
Italian translation (it-it)
Japanese translation (ja-jp)
Norwegian translation (nb-bo)
Dutch translation (nl-nl)
Polish translation (pl)
Portuguese (Brasil) translation (pt-br)
Portuguese translation (pt-pt)
Turkish translation (tr-tr)

If Leafpub is not translated to your language, feel free to open an issue. We'll create a new language repo and you can open a PR to your language.

Code guidelines

We try to adhere as closely as possible to the following code guidelines, and we ask that you do the same. If you follow these basic rules and pay attention to the existing code, you'll be just fine.

When in doubt, try to stay consistent with the rest of the code base and keep it practical. If you feel there's something missing from these guidelines, let the developers know or submit a PR so we can address it.


We generally follow @mdo's code guide for HTML, with the exception of four spaces instead of two.

Quick tips:

  • Always use the HTML5 doctype.
  • Always use double quotes, never single quotes, on attributes.
  • Don't include a trailing slash in self-closing elements.
  • Don't omit optional closing tags (e.g. </li> or </body>).
  • Avoid generated markup in JavaScript.

Example of well-formed HTML:

<!DOCTYPE html>
    <title>Page title</title>
    <img src="images/company-logo.png" alt="Company">
    <h1 class="hello-world">Hello, world!</h1>


We generally follow @mdo's code guide for CSS, with the exception of four spaces intead of two.

Example of well-formed CSS:

/* Good CSS */
.selector[type="text"] {
    padding: 15px;
    margin-bottom: 15px;
    background-color: rgba(0,0,0,.5);
    box-shadow: 0 1px 2px #ccc, inset 0 1px 0 #fff;


Leafpub doesn't have a specific JavaScript code guideline, but here are some rules that we try really hard to follow:

  • Always use semicolons
  • Indent with four spaces (no tabs)
  • Always use strict mode
  • Keep it pretty. Refrain from using long lines and excessive whitespace.
  • Use $().on('click') instead of $().click() (applies to all event aliases)
  • Make sure your work pleases JSHint. There is a Gulp task for this (gulp jshint) and it's automatically triggered by gulp watch


Leafpub doesn't have a specific PHP code guideline, but here are some rules that we try really hard to follow:

  • Indent with four spaces (no tabs)
  • Keep it pretty. Refrain from using long lines and excesive whitespace.
  • Use camelCase for method names, not underscore_naming.
  • Opening braces for methods should be on the same line as the method.
