@invinite-org/create-chartlang

Stability: experimental.

The npm create @invinite-org/chartlang installer — scaffold a runnable chartlang starter app (TanStack Start editor + live chart + Yahoo Finance market data + SQLite) with your chosen chart library wired in. Market data needs no API key.

Usage

npm create @invinite-org/chartlang@latest my-app
# or: pnpm create @invinite-org/chartlang my-app · npx @invinite-org/create-chartlang my-app

It clones apps/react-starter from GitHub, prompts for a chart library (default echarts), vendors the chosen adapter from the CLI's offline bundle, rewrites the single activeAdapter.ts seam + the package.json workspace deps, writes a .env, and (optionally) installs.

create-chartlang [dir] [--library <id>] [--pm <npm|pnpm|yarn|bun>] [--no-install] [--yes]

• dir — target directory (default ./chartlang-starter).
• --library <id> — echarts (default) · lightweight-charts · uplot · konva · canvas2d. Skips the prompt.
• --pm — package manager for the install + printed next steps.
• --no-install — skip the dependency install.
• --yes — accept defaults and overwrite a non-empty target dir.

Public surface

The installer is also importable for programmatic scaffolding / testing:

pnpm add @invinite-org/create-chartlang

import { runCreateChartlang, defaultDeps } from "@invinite-org/create-chartlang";

await runCreateChartlang(["my-app", "--library", "echarts"], defaultDeps({
  cloneStarter: async () => {/* clone the starter tree */},
  runInstall: async () => {/* run the package install */},
}));

runCreateChartlang(argv, deps) runs the flow against an injectable IO seam (CreateChartlangDeps); the network clone + install are injected so the rest is offline + testable. Also exported: seamTemplateFor, rewriteStarterPackageJson, bundleChartlangVersions, resolveAdapter, CHARTLANG_VERSIONS, STARTER_CLONE_REF.

Switching libraries later

npx @invinite-org/chartlang-cli add-adapter <id>
# then edit src/lib/chart/activeAdapter.ts
