### Render asciicast to SVG with JavaScript

Source: https://github.com/marionebl/svg-term/blob/master/README.md

This JavaScript code snippet demonstrates how to use the svg-term library to render an asciicast file into an SVG string. It reads an asciicast JSON file, processes it using the `render` function, and outputs the resulting SVG.

```js
const fs = require('fs');
const {promisify} = require('util');
const readFile = promisify(fs.readFile);
const {render} = require('svg-term');

(async () => {
  const data = String(await readFile('./asciicast.json'));
  const svg = render(data);
  // => <svg>...</svg>
})()
```

### svg-term TypeScript API Definition

Source: https://github.com/marionebl/svg-term/blob/master/README.md

This TypeScript code defines the interface for the `render` function and its associated `Options` and `Theme` types within the svg-term library. It outlines the expected input formats, available customization options like themes, window framing, idle time, FPS, and time range rendering, as well as the structure for defining custom color themes.

```ts
// `input` can be string/object of v1 or v2:
// https://github.com/asciinema/asciinema/blob/develop/doc
// or an already loaded cast:
// https://github.com/marionebl/load-asciicast
//
// `options` won't take effect if `input` is an already loaded cast.
render(input: string, options?: Options): string

interface Options {
  /**
   * ANSI theme to use
   * - has to contain all keys if specified
   * - defaults to Atom One theme if omitted
   **/
  theme?: Theme;
  /** Render with a framing window, defaults to false */
  window?: boolean;
  /** Idle time limit in milliseconds */
  idle?: number,
  /** Frames per second limit, see https://github.com/marionebl/svg-term/issues/13 */
  fps?: number,
  /** Lower bound of timeline to render in milliseconds */
  from?: number;
  /** Upper bound of timeline to render in milliseconds */
  to?: number;
  /** Timestamp of single frame to render in milliseconds **/
  at?: number;
}

interface Theme {
  /** ANSI Black */
  0: RGBColor;

}
