We welcome and encourage community contributions to our projects. This document specifies the guidelines for contributing to the projects that are created under the bigpipe organization. We've split this document in smaller sections:

There are always many ways you can help out this project besides contributing to the code:

  • Writing and improving our documentation.
  • Helping people out in our IRC room.
  • Searching for potential memory leaks, event loops blocks and de-optimized code.
  • Preforming security audits on the code base. Please check our for the Security Guidelines.
  • Filing bugs.

And that list goes on and on. No matter what you choose we are thankful for your interest and for the fact that you want to contribute to our projects. They are build and maintained with love and we hope to share some of that love with you.

Feature Requests

Yes! Make them! We would love to hear your idea(s) and what we can do to continue to move this project forward. Changes, big or small, are always welcomed. If the feature requested is not in line with our roadmap we will work with you to ensure that you can build it yourself on top of our project.


When you're first starting you're bound to have questions about this project. We hope that our documentation in the provides answers to all your questions. In rare cases when the documentation does not answer your question you could:

  1. Join our IRC room and ask the question there. The authors, contributors and users of this project usually hang around there.
  2. By creating an issue on GitHub. Throughly explain your issue, the more information you provide us with the better we can help you.

We will do our best to answer your questions in a timely manner. Please note that if you create an new issue by stuffing the question in the title and no explanation in the body it will be closed and locked immediately and referred to this contribution file.


If you have a security related issue, please review Security Guidelines first.

Before creating an issue make sure that you are using the latest version of the module as the issue you report could be already resolved. If you are using the latest version please use the Github search feature to check if the issue is already known. If you've found an issue that is:

  • closed: Check if the issue provides a solution for your issue. If it's already fixed using a commit it could be that there have been a regression in the code. In this case it's best to open a new issue. For all other cases it might make more sense to just add comment to the closed issue explaining that you're still affected by this.
  • open: Try to provide more details to the issue. If you can reproduce the issue in a different way then the one used by the original author, please add this. The more ways we have to reproduce the bug, the more are the chances to get it fixed fast.
  • missing: Please open a new issue, we would love to hear more about it.

Outline of a good bug report

When reporting new issues for the project please use the following issue template so you know what kind of data you need to supply and we can resolve it as quickly as possible. If some of these fields do not apply to your issue feel free to leave them empty or remove them completely:


  - **Operating system**:
  - **browser**:
  - **Nodejs**:
  - **npm**:

**Expected result:**

**Actual result:**

**Steps to reproduce:**

1. Step 1.
2. Step 2.
3. Things are broken.

Here is a small explanation of the fields and what kind of information could be present in them.

  • Version: The version number of the module that you're currently using. If you don't know the current version number you can check it by running npm ls in your terminal.
  • Environment: This allows us to narrow down the issue to a potential platform or version if we cannot reproduce it on our own machines. If you don't know your npm and node.js version you can run npm version in your terminal and it will output all the information you need. If you are reporting a node.js specific bug you can omit the browser field unless it requires a browser to reproduce it.
  • Expected result: What did you expect would happen.
  • Actual result: What actually happened when you executed the code.
  • Steps to reproduce: Every step to fully reproduce the issue is described here, no matter how small. You cannot be specific enough. It's better to have too much details than too few here.

A complete example of this would be:

Version: 0.0.1
  - Operating System: Mac OSX 10.10.1 (14B25)
  - Node: 0.10.31
  - npm: 1.4.28
  - browser: Google Chrome, Version 39.0.2171.71 (64-bit)

Expected result: A `console.log` message in the terminal.

Actual result: An empty console without any log messages.

Steps to reproduce:

1. Open Chrome.
2. Open the Developer tools panel.
3. Type `console.log('message')`.
4. Press enter to execute the code.

When adding code to your example please use code fencing to ensure that your snippet is highlighted correctly. This greatly improves the readability of the issue.


We try to label all created issues to facilitate the identification of the issue scope. We also label all issues with a . The more stars an issue has the more important it is. We currently have three different levels of importance:

  • ★★★: High priority issue, should be addressed as soon as possible. We will do our best to include this in the next release. This however does not mean that no issue is closed or fixed before these high priority issues.
  • ★★: Medium priority, this should be fixed but it might not make the next release.
  • : Low priority issue, don't expect this to be resolved soon. These bugs are generally fixed on a rainy or boring day. These bugs are also great for first time contributors who are looking for something to fix.


Unless you are fixing a known bug we strongly encourage to discuss your feature with the core team via a GitHub issue or IRC. Before getting started ensure that you work will not rejected.

All contributions must be made via pull requests. After a pull request is made other contributors will either provide feedback or merge it directly depending on:

  • Addition of new tests and passing of the test suite.
  • Code coverage.
  • The severity of the bug that the code is addressing.
  • The overall quality of patch.

We expect that every bug fix comes with new tests for our test suite. This is important to prevent regression in the future as our current set of tests did not trigger the code path.

The Boy Scout Rule

When working with the code try to follow the rule that The Boy Scouts have:

Always leave the campground cleaner than you found it.

If you find a mess on the ground, you clean it up regardless of who might have made the mess. You intentionally improve the environment for the next group of campers. Working with code should not be an exception to this. If you find a mess in the code, clean it up no matter who the original author was.

Code of Conduct

  • We are committed to providing a friendly, safe and welcoming environment for all, regardless of gender, sexual orientation, disability, ethnicity, religion, or similar personal characteristic.
  • Please avoid using overtly sexual nicknames or other nicknames that might detract from a friendly, safe and welcoming environment for all.
  • Please be kind and courteous. There's no need to be mean or rude.
  • Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
  • Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
  • We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behaviour. We interpret the term "harassment" as including the definition in the Citizen Code of Conduct; if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don't tolerate behavior that excludes people in socially marginalized groups.
  • Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact one of the channel ops or any of the core contributors immediately with a capture (log, photo, email) of the harassment if possible. Whether you're a regular contributor or a newcomer, we care about making this community a safe place for you and we've got your back.
  • Likewise any spamming, trolling, flaming, baiting or other attention-stealing behaviour is not welcome.
