This is the unofficial subreddit for the React JavaScript library. The description says it covers all things React, and the rules confirm that posts should be directly related to the React JavaScript library. The community is a mix of professionals and hobbyists, so you are writing for people who range from seasoned engineers to self-taught builders. It is a technical space focused on React itself, not general web development or unrelated programming topics.
The three rules here are short but they cover the main bases. Posts should be related to the React Javascript Library is the gatekeeper for relevance. Be respectful sets the tone expectation for a mixed community of professionals and hobbyists. No low effort posts is the one that catches marketing-style submissions, and it specifically calls out links to articles with LLM-generated content, so AI-written blog posts are explicitly off the table.
A good post here is something genuinely useful to people building with React. If you are a founder, that means sharing a real React-specific problem you solved, a library you built that does something React developers need, or a technical walkthrough that helps someone working in React. The content has to be directly tied to the React JavaScript library, not just adjacent frontend topics. Keep your tone professional and respectful, since the community is made of both professionals and hobbyists.
Do not post anything that is not directly about the React JavaScript library. Do not share articles that contain LLM-generated text, because the rules name that explicitly as low effort. Avoid low quality links and thin content, since the No low effort posts rule is broad enough to cover generic promotional posts. Do not be disrespectful in comments or posts, because the Be respectful rule applies to everyone in the community.

The rules do not explicitly ban promotion, but they do ban low effort posts and content unrelated to React. If your promotion is genuinely useful and React-specific, it has a better chance. A generic marketing pitch will likely be removed as low effort.
No. The rules under No low effort posts specifically say links to articles with LLM-generated content are not permitted.
It must be directly related to the React JavaScript library. General JavaScript, frontend, or web development topics that are not React-specific may be removed under the rule Posts should be related to the React Javascript Library.
The rules ask for respectful posts and say the community is made of professionals and hobbyists alike. A professional, helpful tone is the safe choice.
