## What it does

This rule directs Cursor to write HTMX markup according to core patterns. It prompts the assistant to use attributes like `hx-get`, `hx-post`, and `hx-trigger`, while routing output via `hx-target` and controlling DOM replacement with `hx-swap`.

The configuration proposes a concrete project tree with `src/templates/`, static CSS and JS directories, and an `app.py` entry point. It also enforces server-side engines such as Jinja2 or Handlebars, semantic HTML5, and full navigation via `hx-boost`.

Security and resilience matter here: the rule mandates CSRF defense, proper error handling, and progressive enhancement. Because `alwaysApply` is set to `false`, Cursor does not attach these instructions automatically to every prompt.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/htmx-basic-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/htmx-basic-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/htmx-basic-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/htmx-basic-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/htmx-basic-cursorrules-prompt-file.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/htmx-basic-cursorrules-prompt-file.mdc

## When to use it
- configure `hx-target` and `hx-swap` for targeted DOM updates
- organize template and asset folders for an `app.py` application
- attach loading indicators to requests with `hx-indicator`
- enable fast multi-page transitions using `hx-boost`

## Example prompts
- Create an item submission form using `hx-post` with a loading indicator
- Update the notifications list with `hx-swap` into the target container
- Set up navigation links across the template with `hx-boost`
