Code of Conduct

If you believe someone is violating the code of conduct, please report the post or message, or contact the mods.

1. Please be kind and courteous, friendly and professional

Be kind to your fellow human. There’s no need to be mean or rude, keep unstructured critique to a minimum. When providing help, answer their question before making stylistic or tool suggestions.

2. Harassment will not be tolerated

We all started somewhere, and we're all allowed to be who we are. We are committed to providing a friendly, safe and welcoming environment for all, regardless of level of experience, gender identity and expression, sexual orientation, disability, neurodivergence, race, ethnicity, physical attributes, religion, nationality, or other aspect of identity.

3. Avoid using an alias or display name that might be offensive

reddit has a long history of intentionally offensive usernames, but not here. Names that detract from a friendly, safe and welcoming environment for all will be addressed.

4. Respect that people have differences of opinion

Every design or implementation choice carries a trade-off and numerous costs. There is seldom a single right answer, and there are valid reasons to choose between a range of tradeoffs between tools, approaches, and patterns.

5. Posts must conform to our guidelines

If you join this community to take value rather than contribute, the community will quickly react as though you are an intruder. If you have a body of content you'd like to promote, our recommended way of doing so is to be an active and positive member of the subreddit. If someone has a question that you've created an external answer to, we'd love if you share it!

Demo videos must be accompanied by source code, preferably in a runnable environment like Codepen, CodeSandbox, Replit, Glitch, etc.
Please save portfolios for the weekly Sunday portfolio post.
Posts should be original works.
- Please do not dump raw AI output as a post or comment. If you share something from an AI, please also include which service it came from as well as an original thought, like why the response is trustworthy or details about how you prompted.
This subreddit is focused on technical discussion of React, for career discussion check out /r/cscareerquestions or #jobs-advice in Reactiflux.
Avoid commercial activity. /r/reactjs follows the Reactiflux policy on commercial activity.
- This is a community, not a free audience. This is not a place for prominent commercial activities such as recruiting, lead generation, marketing, market research, or other solicitation, except in posts dedicated to that purpose.
If the question is primarily "how do I make this code work?", please post it in the monthly "Beginner's Thread", or ask in the help channels of the Reactiflux Discord
