- is a wonderfully dynamic language and its dynamic features afford you a great deal of expressiveness.

- Strong typing is useful for catching errors before runtime.

These two statements don’t have to be mutually exclusive.

Instead of shackling yourself to ™ 2023™ Enterprise Edition™, you can use to get the best of both worlds.

Here, for example, I’m mixing a property into Polka request handlers and annotating it. My intent is clear and the type checker’s happy.

Screenshot of code for Server.js class showing the type definitions for the FilePathMixin and a typedef that mixes it into Polka’s Middleware class. Relevant lines: /** @typedef {{ filePath: string }} FilePathMixin */ /** @typedef {import('polka').Middleware<any> & FilePathMixin} HandlerWithFilePathMixin */
Screenshot of different section of Server.js file showing the Polka handlers in a forEach loop being cast to the HanderlerWithFilePathMixin: // Does this route require authentication? let authenticationRequired = false const route = this.app.find(request.method, request.url) route.handlers.forEach(handler => { const handlerWithFilePathMixin = /** @type HandlerWithFilePathMixin */ (handler) if (handlerWithFilePathMixin.filePath !== undefined) { if (handlerWithFilePathMixin.filePath.match(authenticationRequiredIndicator) !== null) { authenticationRequired = true } } }) if (authenticationRequired) { // Person needs to authenticate to access this route. request.session.redirectToAfterSignIn = request.path response.writeHead(303, { Location: '/sign-in/' })
