edge-comments

Convention-based comments engine for the edge, built on Cloudflare Workers KV and written in Rust via workers-rs.

Data is stored at the exact path it is posted to, so your URL scheme doubles as your storage scheme — no database or schema required.

API

Method	Path	Description
POST	/path/to/data	Store the text/plain body at the path
GET	/path/to/data	Fetch the stored value as text/plain
GET	/path/to/	List all keys under the prefix (newline-delimited; note the trailing slash)

For example, if you have 3 blogs you can store comments like: /blog3/my-post-slug/comment-id/reply-id/second-level-reply

Quick start

You need a stable Rust toolchain with the wasm32-unknown-unknown target (pinned via rust-toolchain.toml) and wrangler v4+.

1. Copy wrangler.example.toml to wrangler.toml and set your KV namespace id
2. Run a local dev server: npx wrangler dev
3. Deploy to the Cloudflare network: npx wrangler deploy

Status and limitations

• No authentication yet. This should be an origin block and preferably some form of user authentication — contributions welcome (see CONTRIBUTING.md).
• Licensed under MIT. By participating in this project you agree to the Code of Conduct.

References

• Bootstrapped from the workers-rs template — the Rust SDK for Cloudflare Workers. Rust-based Workers compile to the wasm32-unknown-unknown target, and so must all dependencies.
• worker crate documentation
