CDN

You can use unpkg:

https://unpkg.com/lightweight-charts/dist/lightweight-charts.standalone.production.js

The standalone version puts all exports from esm version to window.LightweightCharts:

const chart = LightweightCharts.createChart(document.body, { width: 400, height: 300 });
const lineSeries = chart.addLineSeries();
lineSeries.setData([
    { time: '2019-04-11', value: 80.01 },
    { time: '2019-04-12', value: 96.63 },
    { time: '2019-04-13', value: 76.64 },
    { time: '2019-04-14', value: 81.89 },
    { time: '2019-04-15', value: 74.43 },
    { time: '2019-04-16', value: 80.01 },
    { time: '2019-04-17', value: 96.63 },
    { time: '2019-04-18', value: 76.64 },
    { time: '2019-04-19', value: 81.89 },
    { time: '2019-04-20', value: 74.43 },
]);

Development

Compiling

• npm run tsc - compiles source code only (without tests)
• npm run tsc-watch - runs the TypeScript compiler in watch mode for source code (the same as tsc, but in watch mode)
• npm run tsc-all - compiles everything (source code and tests)
• npm run tsc-all-watch - runs the TypeScript compiler in watch mode for source code and tests (the same as tsc-all, but in watch mode)

Bundling

• npm run rollup - runs Rollup to bundle code
• npm run build - compiles source code and bundles it (a short-hand for npm run tsc && npm run rollup)

Note: by default only dev version is bundled. To bundle a production builds (minified) too just set NODE_ENV variable to production and run bundling. For example: NODE_ENV=production npm run rollup.

Testing

• npm run lint - runs lint for the code
• npm run test - runs unit-tests

Tips

To make sure that your local copy passed all (almost) checks, you can use a verify npm script: npm run verify.
