Team best practices

This document aims to address contributors best practices of the following repositories:

This document is not in its final version, a team meeting which aims to address new/old best practices, feedback, workflows, all kind of issues related to how the team works together occurs every 2 weeks. This document link to other specialized best practices (like coding best practices).

Team communication

1) Team meetings:

  • Daily standup (1pm CET - 11am GMT) for taking care of the current issues.

  • A regular standup - each Tuesday (3pm CET - 1pm GMT) - which aim to

    • Update every contributor on what others are doing.
    • Update the prioritised issues / PRs list.
    • Address little issues (possibly related to the current ongoing milestone).
    • High level demo, explanation about specific points of the codebase or Ethereum related things.

  • A milestone standup - scheduled before the beginning of each milestone, roughly on a monthly basis - which aim to define what will be included in the next milestone and who will work on what. This standup also help to set a clear long term vision.

  • A retrospective standup - after each release - which aims to talk about best practices in general: what is good, what is bad, how we can improve workflows.

  • A tour standup - Just after a release or whenever it is needed - which aim to demo, explain in details features, bug fixes or any part of the codebase.

2) Group meetings:

  • When a story / bug fix is divided in parts, there should be a kickstart meeting with all the developers involved, so that all the devs have a good overview / understanding on:
    • How the story fits into the Ethereum tech.
    • How the backend (if any) works / will work (could be a smart contract).
    • How the frontend works / will work.
    • What is the general vision of the UX design for this particular story. Later progress and discussion is updated directly on the issue or pull request (GitHub).

Prerequisites:

Before starting coding, we should ensure all devs / contributors are aware of:

Story / Bug fix

  • Prioritised list of PRs / issues are tracked in a GitHub Project, Remix IDE issues are managed by a prioritized backlog.
  • Every story can be executed by a single developer or a group of 2 or more developers (depending on the size and complexity)
  • Each dev should take the part he/she feels the most comfortable with.
  • Later progress and discussion is updated directly on the issue or pull request (github).
  • When a developer or team decides on the story they want to work on (at the start of milestone for instance), they assign themselves to the issue.
  • Documentation update should be done together with the story, or an issue with the label "documentation" has to be created.

Pull Requests

1) PR Creator:

  • It is recommended to use the emoji responses to signal agreement or that you've seen a comment and will address it rather than replying. This reduces github inbox spam.
  • Mark unfinished pull requests with the Work in Progress label
  • Large pull requests (above 200-400 lines of code changed) cannot be effectively reviewed and should be split into smaller pieces.
  • Code should comply to the JavaScript standard style - https://www.npmjs.com/package/standard
  • You should not expect complete review on a pull request which is not passing CI.
  • You can obviously ask for feedback on your approach.
  • You should assign a reviewer(s).
  • Pull requests should be used as a reference to update coding best practices whenever it is needed.

2) Review:

  • Everyone is free to review any pull request.

  • You should add the label "change requested" or "accepted".

  • When reviewing people's code consider the following two comments.

    I don't like the name of this function.

    vs.

    What do you think about changing the name of this function to ....

    Your feedback will often be better received if you pose it in the form of a question.

  • Pull request should be reviewed to comply to coding best practices.

  • You should take the responsibility of the PR you are reviewing.

  • You should make sure the app is viable after the PR is being merged.

  • You should make sure the PR is correctly tested (e2e tests, unit tests)

  • Ideally You should have enough knowledge to be able to fix related bugs.

3) Merge:

  • Merging is possible after Review and Tests are ok and when the PR is approved.
  • After a merge, it is highly recommended to check the new code in remix-alpha.ethereum.org

Milestone

  • A milestone should only contain items we are sure to finish.
  • The end of a milestone triggers a new release.
  • Milestone items and duration should take in account time spent in bugs fixing and support.
  • The team should commit to the milestone duration.
  • If a dev finish early he/she can help others to push remaining tasks.
  • If a dev finish early he/she can work on specifying / integrating the next milestone.
  • A milestone duration is fixed at the start of the milestone (but should better not exceed 1 month).
  • Progress and issues regarding a milestone are discussed on regular standups.

Milestone - Refinement meeting

  • A meeting is organized 3 weeks after the beginning of a round. This aims to :
    • list what is left to do.
    • identify any blocker.
    • agree on a release date (which can be earlier 1 week after the meeting and not later than 4 weeks after the meeting.
    • add issues that are eligible to get in the release.
    • remove issues that aren't doable in time or represent a risk.
    • plan for asking feedback about new features (in social media).

Releases

1) Process:

  • Should be documented and updated.
  • A new release is triggered:
    • after an important bug fix
    • at the end of a milestone
  • We can release an m.m.m-alpha.x (whenever we need to release and for whatever reasons) being in between a feature / bug fix completion.
  • We release an m.m.x whenever there is a bug fix.
  • We release an m.x.0 whenever there is a new feature.
  • We release an x.0.0 after each milestone we consider being an important progress.
  • We release an x.0.0 if there's an API breaking change in one of our libraries.
  • After a new release we should stay in alert for possible regression and better not release Friday at 5pm :)

2) Community:

  • Before the official release, we should select a group of power users and invite them to test and give feedbacks.
  • Users need to know upfront a new release is coming and we should prepare them for it by showcasing some new features they can expect and when it will happen (fixed date, published at least 1 week in advance).
  • Whenever we have a new release we have to communicate this efficiently (twitter, reddit, ...).

Maintenance

1) Bugs:

  • A critical bug should get the label Blocker, and every effort should be put to fix it.
  • Addressing a non critical and non planned bug can be done:
    • After having notified in the remix-dev channel if the bug does not involve UX or public API changes.
    • After a dev meeting (e.g the regular standup) if the bug involves any UX or public API changes.

2) Support:

  • We should all keep an eye on the public non dev channel and file user feedback.

3) Documentation:

  • The documentation is done / updated just after the feature / release in a team effort.
  • Documentation work is fileable as a github issue.
  • It is encouraged to find and link associated doc produced by the community (blog posts, videos, tutorials, ...)
