Documentation for JavaScript projects has traditionally been generated via annotations inserted as code comments. While this gets the job done, it seems far from ideal. In this post, I’ll explore how to use TypeScript to generate documentation from source code alone.

TypeScript is JavaScript with optional types. Here’s a simple example:
// Sends some data to some analytics endpoint
function sendAnalyticsJS(data) {
if (typeof data.type !== 'string') {
throw new Error('The `type` property is required')
}
navigator.sendBeacon('/beacon', JSON.stringify(data))
}
// Results in run-time error
// The `type` property is required
sendAnalyticsJS({ foo: 'bar' })
The JavaScript code will result in a run-time error. This is fine if the developer catches it early, but it would be better if the developer were warned as the bug was introduced. Here’s the same code written using TypeScript:
// Describe the shape of the data parameter
interface IAnalyticsData {
// Type is required
type: string
// All other fields are fair game
[propName: string]: string
}
// We don’t particularly need the data.type check here since
// the compiler will stamp out the majority of those cases.
function sendAnalytics(data: IAnalyticsData) {
