Fly.js vs rollup: What are the differences?

Configuration Options: Fly.js provides a wide range of configuration options for customizing builds, such as defining custom input and output directories, setting up external plugins, and specifying target environments. On the other hand, Rollup offers a more streamlined configuration approach with its simple and intuitive configuration file, making it easier for beginners to get started with building projects.
Code Splitting: Fly.js allows for efficient code splitting by automatically analyzing dependencies and generating separate bundles for different modules or components. In contrast, Rollup also supports code splitting but requires manual configuration to specify entry points for splitting code, which provides more control and flexibility but can be complex for some users.
Treeshaking: Fly.js utilizes a powerful treeshaking algorithm to analyze and eliminate unused code from the final bundle, resulting in smaller and more efficient builds. Rollup also has treeshaking capabilities, but Fly.js generally produces smaller bundle sizes due to its more advanced optimization techniques.
Community and Ecosystem: Rollup has a larger and more active community compared to Fly.js, offering a wider range of plugins, documentation, and support resources. While Fly.js is steadily growing its community, Rollup has established a stronger presence in the JavaScript ecosystem, making it a popular choice for many developers.
Build Performance: Fly.js is known for its blazing-fast build times due to its efficient build pipeline and optimization strategies, making it ideal for projects that require quick iterations and deployments. Rollup is also fast but may lag behind Fly.js in terms of overall build performance, especially for larger projects with complex dependencies.
Bundle Size: When it comes to bundle size optimization, Fly.js tends to produce smaller and more optimized builds compared to Rollup, thanks to its advanced code analysis and optimization techniques. This difference can be crucial for projects where minimizing bundle size is a high priority, such as web applications targeting resource-constrained devices or networks.

In Summary, Fly.js and Rollup differ in configuration options, code splitting, treeshaking capabilities, community support, build performance, and bundle size optimization.

Advice on Fly.js, rollup

Abigail

Dec 10, 2019

Decided

We mostly use rollup to publish package onto NPM. For most all other use cases, we use the Meteor build tool (probably 99% of the time) for publishing packages. If you're using Node on FHIR you probably won't need to know rollup, unless you are somehow working on helping us publish front end user interface components using FHIR. That being said, we have been migrating away from Atmosphere package manager towards NPM. As we continue to migrate away, we may publish other NPM packages using rollup.

Detailed Comparison

Fly.js	rollup
Fly is a modern build system for Node based in co-routines, generators and promises. Fly has robust error handling, callback heaven, cascading tasks, parallel execution and a simple API. See the documentation to learn more about how to use Fly and write your own plugins.	It is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD.

Pros & Cons
No community feedback yet	Pros 4 Makes it easy to publish packages 3 Easier configuration 2 Provides smaller bundle size 2 Better tree shaking 1 Integrates seamlessly with SystemJS Cons 1 Manual Chunking is a bit buggy 1 Almost everything needs to be a Plugin 1 No Loader like Webpack (need to use sjs or ESM imports) 1 No clear path for static assets

What are some alternatives to Fly.js, rollup?

gulp

Build system automating tasks: minification and copying of all JavaScript files, static images. More capable of watching files to automatically rerun the task when a file changes.

Webpack

A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows to load parts for the application on demand. Through "loaders" modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.

Grunt

The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes. After you've configured it, a task runner can do most of that mundane work for you—and your team—with basically zero effort.

Brunch

Brunch is an assembler for HTML5 applications. It's agnostic to frameworks, libraries, programming, stylesheet & templating languages and backend technology.

Parcel

Parcel is a web application bundler, differentiated by its developer experience. It offers blazing fast performance utilizing multicore processing, and requires zero configuration.

Backpack

Backpack is minimalistic build system for Node.js. Inspired by Facebook's create-react-app, Zeit's Next.js, and Remy's Nodemon, Backpack lets you create modern Node.js apps and services with zero configuration. Backpack handles all the file-watching, live-reloading, transpiling, and bundling, so you don't have to.

Vite

It is an opinionated web dev build tool that serves your code via native ES Module imports during dev and bundles it with Rollup for production.

Pingy CLI

Gulp and Grunt and other heavyweight build tools are great for complicated build workflows. Sometimes you want something simpler that doesn't take lots of configuration to get up and running. That's Pingy CLI.

Microbundle

Zero-configuration bundler for tiny modules, powered by Rollup.

System.js

It is a Universal Module Loader for JavaScript. If you've used RequireJs or a CommonJs bundler in the past, you have probably created modules.Configurable module loader enabling dynamic ES module workflows in browsers and NodeJS.
