charting-library-downloader

CLI tool that downloads the TradingView Charting Library from TradingView's public CDN and saves a complete, self-contained copy to your project.

It starts from the library entry files, walks webpack runtime bundles to discover chunk dependencies, and downloads referenced CSS, fonts, WASM, and locale bundles. The result is ready to serve from your app (for example under public/charting_library/).

Requires Bun — this package is intended to be run with bunx.

What it downloads

From https://trading-terminal.tradingview-widget.com/charting_library/:

• Root assets: charting_library.js, ESM/CJS builds, TypeScript definitions, sameorigin.html, and package.json
• Webpack bundles/ chunks discovered by parsing the runtime and dependency graph
• CSS bundles (including RTL variants when present)
• Locale bundles for all supported languages, or a single locale when --locale is set
• Assets referenced in downloaded files (url(...), fonts, SVG, WASM, etc.)

After a successful run, the output directory contains the library files plus charting-library-download-manifest.json with download stats, file list, and any optional or failed paths.

Install & run

No install step is required. Run directly with Bun:

bunx charting-library-downloader --out ./public/charting_library

Download only one locale (smaller output, faster):

bunx charting-library-downloader --out ./public/charting_library --locale en

Show help:

bunx charting-library-downloader --help

Options

| Option | Description | |--------|-------------| | --out <dir> | Output directory (required). Created if it does not exist. | | --locale <code> | Download bundles for one locale only (e.g. en, de, zh_TW). Without this flag, all supported locales are fetched; missing optional locale files are skipped. | | --help, -h | Print usage and exit. |

Local development

Clone the repo and run the entry file with Bun:

bun install
bun run index.ts --out ./out/charting_library

Exit codes

• 0 — all required files downloaded
• 1 — one or more required downloads failed (see manifest / stderr summary)

Optional locale files that are not available on the CDN are recorded in the manifest and do not fail the run.

Publishing

From the package root, after logging in to npm:

bun pm pack   # optional: inspect the tarball
bun publish --access public
