swc

swc is a JavaScript and TypeScript compiler written in Rust. The goal is to provide faster compilation speed and better compression than Babel. The name of swc is the abbreviation of "Super-fast Web Compiler". It has the following characteristics:

High performance: swc is many times faster than Babel in compilation speed, thanks to its use of Rust, a high-performance language, as the development language. swc also supports multi-threaded compilation, which can better utilize multi-core CPU resources to speed up the compilation process. In addition, unlike Babel, swc directly parses the code into AST, avoiding Babel's dependence on other grammar libraries and further improving performance.
Excellent compression effect: swc aims at "super-fast and pure". It not only performs well in terms of compilation speed, but also produces smaller and more efficient code than Babel. . swc provides a variety of compression options, such as removing unused code, obfuscating variable names, converting ECMAScript modules, etc., which can be adjusted as needed.
Support the latest ECMAScript standards: In addition to supporting regular JavaScript compilation, swc also supports the latest ECMAScript standards, including ES6, ES7, ES8, etc. swc supports all major browsers and Node.js, and has wide applicability.
Support TypeScript: In addition to JavaScript compilation, swc also supports TypeScript compilation and can be integrated with mainstream front-end frameworks such as React and Vue. swc can directly compile TypeScript code into JavaScript code, making the project code easier to maintain and modify.
Easy to integrate: swc’s API is friendly and easy to use, and can be integrated into existing build systems. swc supports mainstream build tools such as webpack, rollup, and Parcel, and can be installed through npm.

swc has the following shortcomings:

Relatively unstable: swc is very young and developing rapidly, so its stability is not as stable as old tools such as Babel . Its API may change in future versions, and there may be some bugs or incompatibility issues. Therefore, sufficient testing and evaluation are required when using swc to ensure the stability of the project.

Although swc already has some common plug-ins, such as TypeScript conversion and code compression, it may not meet all needs and needs to be handled by developers themselves.
Compatibility issues: Since swc is a new tool and is developed using Rust, there may be some compatibility issues. For example, integration with other tools or libraries may require additional modifications or adjustments, and some external libraries may not be compatible with swc.

Rollup

Rollup is a JavaScript module packager that can package JavaScript modules into a single file. Compared with other packaging tools, Rollup pays more attention to the support of ES6 modules. It can convert ES6 modules into ES5 modules and perform tree-shaking optimization to reduce the size of the packaged files. The goal of Rollup is to produce smaller, faster, and more efficient code, so it is very useful when building JavaScript libraries.

The advantages of Rollup are as follows:

Tree shaking: Rollup has built-in Tree shaking, which can statically analyze the code and package only the parts actually used in the project. This means the resulting bundles are smaller in size, load faster, and avoid unnecessary code execution.
ES6 Module Support: Rollup supports ES6 module syntax, which is part of the JavaScript standardization and is supported in modern browsers and Node.js. This allows Rollup to perform static analysis between ES6 modules, optimizing the resulting code.
Plug-in system: Rollup has a powerful plug-in system that can perform various conversions and processing of input codes and output results. For example, plugins can convert TypeScript code into JavaScript, convert CSS files into JS modules, or compress the final generated code, etc.
Support for third-party libraries: Rollup’s plug-in system can also be integrated with third-party libraries, such as mainstream frameworks such as React and Vue.js. These plugins mark framework components as external dependencies to avoid packaging the same code multiple times.
Multiple output formats: Rollup supports multiple output formats, including CommonJS, AMD, UMD, ES6, etc.

Rollup has the following disadvantages:

High complexity: Compared with other packagers, Rollup's learning curve may be steeper because its configuration requires more understanding. In particular, in some cases, such as when working with non-JavaScript resources like images and fonts, you may need to use additional add-on plugins or tools.
Insufficient support for some CommonJS modules: Since Rollup is specially designed for ES6 modules, it has weak support for libraries written in the CommonJS format. Although Rollup can support CommonJS through plugins, not all libraries are suitable for this method, which may cause problems when packaging.
