# tinyest

Tiny Embeddable Syntax Tree -
[GitHub](https://github.com/software-mansion/TypeGPU/tree/main/packages/tinyest)

</div>

A compact, fast, and embeddable JavaScript AST for transpilation.

### Source mapping

Tinyest supports source mapping. 
Use `embedSourceMap` function to obtain a new node with the source map embedded.
Use `stripSourceMap` function to restore the original node and source map.

Note that both functions create a new AST instead of modifying the existing one:

```ts
const node: Identifier = [NodeTypeCatalog.identifier, 'ident'];
const sourceMap: SourceMap = new Map([[node, [1, 2]]]);

const sourceMappedNode = embedSourceMap(node, sourceMap);
const [restoredNode, restoredSourceMap] = stripSourceMap(sourceMappedNode);

console.log(restoredNode); // [9, 'ident'];
console.log(restoredSourceMap.get(restoredNode)); // [1, 2];

console.log(node === restoredNode); // false
console.log(restoredSourceMap.get(node)); // undefined
```
