Bundler
Refers to module bundlers such as Rspack and Webpack.
The main goal of bundlers is to bundle JavaScript, CSS and other files together, and the bundled files can be used in the browser, Node.js or other environments. When bundler processes the Web application, it builds a dependency graph and then combines every module into one or more bundles.
CSR
CSR stands for "Client-Side Rendering". It means that the page is rendered in the browser using JavaScript, and logic such as data fetching, templates, and routing is completed on the client side rather than the server.
In CSR, the server sends an empty HTML shell and some JavaScript scripts to the browser, and the browser fetching data from the server's API and renders dynamic content to the page.
Micro-frontend
Micro-frontend (MFE) is an architecture style similar to microservices. It is a composition of multiple independently delivered frontend applications, forming a cohesive whole. MFE decomposes frontend applications into smaller, simpler applications that can be developed, tested, and deployed independently while still appearing as a cohesive single product to users.
It primarily addresses two problems:
- Difficulty in maintaining large and complex applications as they evolve over time.
- Inefficiency caused by cross-team or cross-department collaboration in project development.
Modern.js
Modern.js is an open source web engineering system from ByteDance, which provides multiple solutions to help developers solve problems in different development scenarios.
Module Federation
Module Federation (MF) is a feature of Webpack. It allows a JavaScript application to dynamically load code from another application, and in the process, share dependencies. If an application consuming a federated module does not have a dependency needed by the federated code, Webpack will download the missing dependency from that federated build origin.
This allows for the creation of micro-frontend-style applications, where multiple systems can share code and be dynamically updated without having to rebuild the entire application.
Rsbuild provides an example project for Module Federation. Please refer to examples - module-federation.
You can also read the webpack Module Federation documentation to learn more concepts.
Rspack
Rspack is a high performance JavaScript bundler based on Rust, with interoperability with the webpack ecosystem, allowing it to be integrated into webpack projects at a low cost while providing better build performance.
Compared to webpack, Rspack has significantly improved build performance, thanks not only to the language advantages brought by Rust, but also to its parallel architecture and incremental compilation features. Benchmarking has shown that Rspack can provide 5-10 times better compilation performance.
Rspress
Rspress is a fast static site generator based on Rsbuild.
SSR
SSR stands for "Server-Side Rendering". It means that the HTML of the web page is generated by the server and sent to the client, rather than sending only an empty HTML shell and relying on JavaScript to generate the page content.
In traditional client-side rendering, the server sends an empty HTML shell and some JavaScript scripts to the client, and then fetching data from the server's API and fills the page with dynamic content. This leads to slow initial page loading times and is not conducive to user experience and SEO.
With SSR, the server generates HTML that already contains dynamic content and sends it to the client. This makes the initial page loading faster and more SEO-friendly, as search engines can crawl the rendered page.
SWC
SWC (Speedy Web Compiler) is a transformer and minimizer for JavaScript and TypeScript based on Rust. SWC can provide the same abilities with Babel, and it's more than 10x faster than Babel.
Rsbuild supports SWC by default, power your web application with polyfill and minification.
