# `js-ast`

This is a monorepo with packages to **boost the [DX]** of working with [AST] _(using [JavaScript] programming language)_ related to:

- ![JavaScript icon][icon-js] [JavaScript]

- ![TypeScript icon][icon-ts] [TypeScript]

- ![Svelte icon][icon-svelte] [Svelte]

---

## Core goals

1. [DX] friendly.

1. **Cross-runtime** friendly—👈 this also means [ESM] only.

1. [e18e] friendly.

1. **No build step**—meaning you can debug/edit source code inside `node_modules` as it is.

1. Extensive tests.

---

## Packages

In order to work with AST, the following processes are recognized:

1. [Building](#build) programmatically the [AST] node(s), or an entire object.

1. [Parsing](#parse) _stringified_ code syntax into [AST] object.

1. [Traversing](#traverse) the [AST] object.

1. [Printing](#print) the [AST] object back into _stringified_ code syntax.

> [!IMPORTANT]

>

> The following lists of packages contains **what you can combine together - based on shared [AST] node interface format - aligned with [ESTree] specification**.

> [!NOTE]

>

> Not all of these packages are part of this monorepo.

### Build

Sometimes you need to do some code transformation...
