rbtr-lang-javascript

JavaScript, TypeScript, and TSX support for rbtr. A default plugin — installed with rbtr itself (pip install rbtr).

What it ingests

One plugin, three ids across two grammars: javascript (.js / .mjs / .jsx), typescript (.ts), and tsx (.tsx). A symbol's leading JSDoc is folded into its chunk content.

• Functions — declarations, generators, and arrow functions bound to a const; class/object methods (class members scoped to their class).
• Classes — classes, and TypeScript interfaces, enums, type aliases, and namespaces (a namespace also scopes its members).
• Variables — module-level const / let (including destructuring).
• Re-exports — export * from "./c" and export { x } from "./b" read from another module, so they resolve as imports do. A consumer reaches a symbol through them without ever naming the file that defines it.
• Imports — import, import type, namespace, default, and side-effect imports → import chunks with resolved module + names, for cross-file edges.

Chunks produced

function greet(name) { … }        // function "greet"
const add = (a, b) => a + b;      // function "add"
class Button { render() {} }      // class "Button"; method "render" scope "Button"
export const MAX = 100;           // variable "MAX"
import { x } from "./x";          // import, metadata {module: "./x", names: "x"}

Embedded / injected chunks

None of its own — JavaScript/TypeScript are embedded by the HTML, Markdown, and SFC (Vue/Svelte) plugins, which delegate <script> blocks and fenced code here.

Grammar & dependencies

Uses the tree-sitter-javascript and tree-sitter-typescript grammars. No runtime dependency on other language plugins; the test suite dev-depends on rbtr-lang-css so the sample's styles.css extracts and the cross-file edges snapshot.
