Update gulp configuration to integrate TypeScript into the build process

Question

Update gulp configuration to integrate TypeScript into the build process

In the process of updating the build system for my Angular 1.5.8 application to support Typescript development, I encountered some challenges.

After a complex experience with Grunt, I simplified the build process to only use Gulp and Browserify to generate two bundles: my-lib.js and my-app.js. This setup allows the library and application code to compile efficiently without unnecessary delays. The team and I are satisfied with the current setup.

As we prepare to transition to Angular 2.0 and embrace Typescript development, I am unsure about the best approach to integrate it into our build process. Should I rely on tsc solely for compiling Typescript to Javascript and let Browserify handle dependencies, or should I make tsc the primary build tool to manage dependencies, create mapping files, and produce bundles?

Given the rapid evolution of Typescript and Gulp, I have struggled to find relevant documentation for this specific use case. Any insights from experienced individuals familiar with the latest versions of these tools would be greatly appreciated.

Similar exercises have been conducted at my workplace, nearing completion. Utilizing webpack for most tasks, although it does resemble grunt to some extent. After working with gulp, I'm not particularly fond of grunt.

We've employed webpack for converting ts to js, bundling, and minification. However, we haven't utilized it yet for converting html to js strings or css to js.

Concerning the di aspect, the focus is primarily on js to ts. The conversion from ts to js is managed by Angular's string-based di. For ts to ts, defining necessary interfaces is crucial for future migration from js to ts. It's advisable to start with core components with minimal dependencies.

UPDATE To address the advantages of using gulp, especially in migration scenarios, it's important to note that the transition won't occur all at once. Thus, tsc should handle what's moved to TS, while gulp manages the rest.

Gulp serves a larger purpose beyond just ts to js conversion. We continue to utilize it for creating deployment packages, injecting js into html, rectifying bootstrap font paths, converting small images to base64, and more.

Transpiling TypeScript: The primary goal of tsc is to compile TypeScript files into JavaScript.

Gulp in Action: On the contrary, gulp serves as a versatile build tool capable of executing a variety of tasks like TypeScript compilation, SASS processing, minification, concatenation, and more.

For a demonstration of how to integrate TypeScript and Browserify using gulp, check out this link: https://www.typescriptlang.org/docs/handbook/gulp.html

Alternatively, instead of relying on gulp, an alternative method involves utilizing npm scripts. A sample implementation can be found here:

In my opinion, the easiest way to achieve this is by utilizing Zwitterion. For a brief introduction, you can check out this informative article.

Zwitterion enables you to seamlessly integrate TypeScript directly into the browser using regular script tags. All TypeScript functionalities are readily accessible, as the code is transpiled server-side on a per-file basis before being delivered to the client. It leverages SystemJS to mimic the actual ES module loader behavior that will become standard across all browsers. If you require this functionality for production purposes, you can generate a static build with Zwitterion. This eliminates the need for bundling, leaving you with the decision to prioritize performance according to your specific requirements. Personally, I believe that performance issues will not be significant with HTTP2, and I personally lean towards simpler builds over the complexities associated with webpack and its counterparts.

When moving forward with using TypeScript, consider integrating a module bundler like webpack (my personal favorite). This will utilize ts-loader internally to transpile your code. Additionally, you can take advantage of ts-lint for static code analysis (handled by webpack). Webpack is also beneficial for creating multiple modules. I recommend trying out Yeoman's generator-fountain-webapp at https://github.com/FountainJS/generator-fountain-webapp. After scaffolding, take a look at the generated gulp files to get a better understanding of TypeScript integration.

To simplify your gulp setup and avoid overengineering, consider utilizing the plain TypeScript compiler in the following steps:

1. Begin by installing typescript locally to prevent conflicts with your global tsc:
    npm i typescript --save-dev

2. Next, add tsc as an npm script within your package.json file:
    "scripts": {
        "tsc": "tsc"
    }

3. Create a customized tsconfig.json file tailored to your specific requirements and place it in the same directory as your package.json:
    https://www.typescriptlang.org/docs/handbook/tsconfig-json.html

4. Utilize the tsc compiler directly through gulp by incorporating the following code snippet:
    var child_process = require("child_process");

    gulp.task("build", function(cb) {
        var tsc = child_process.spawn("npm", ["-s", "run", "tsc"], {stdio: "inherit", cwd: __dirname});
        tsc.on("close", function(code) {
            console.log("Tsc finished with code", code);
            cb();
        });
    });
