Nex Framework — AI Agent Guide

7. Commit Convention

Follow Conventional Commits:

• Format: <type>(<scope>): <subject>
• Subject: ≤50 chars, imperative mood
• NO triple backticks in commit messages

---

8. Additional Rules

• English Only: All code, comments, docs, commits in English
• Changelog First: Update changelog before any framework change
• No Config Files: Use .env only, never config/*.exs
• Cursor Rules: If project has .cursorrules, follow it (see bestof_ex/.cursorrules)

---

9. Nex Request Contract

• Canonical Request Type: Page Actions in src/pages/ receive Nex.Req.
• API Consistency: API Handlers in src/api/ also receive Nex.Req.
• Comparison Target: Model Nex request handling after Next.js Pages Router API Routes.
• Parameter Access: Read path params and query string values from req.query. Read request body values from req.body.
• Do Not Model After: Do not model Page Actions after App Router Route Handlers, Server Actions, FormData-first handlers, or a flat merged params map.
• Keep The Contract Visible: When the request argument is unused, prefer _req, not _params.

Example:

def save(req) do
  id = req.query["id"]
  name = req.body["name"]

  {:ok, %{id: id, name: name}}
end

Source Code Reference

Source code for dependencies is available in opensrc/ for deeper understanding of implementation details.

See opensrc/sources.json for the list of available packages and their versions.

Use this source code when you need to understand how a package works internally, not just its types/interface.

Fetching Additional Source Code

To fetch source code for a package or repository you need to understand, run:

npx opensrc <package>           # npm package (e.g., npx opensrc zod)
npx opensrc pypi:<package>      # Python package (e.g., npx opensrc pypi:requests)
npx opensrc crates:<package>    # Rust crate (e.g., npx opensrc crates:serde)
