Clearing away legacy assumptions Collapsing layers of tooling The Third
Age 2020 and beyond
• Synchronous, designed for server environments • Doesn’t natively work
on browsers • Doesn’t work too well with static analysis tools Clearing away legacy assumptions Reliance on CommonJS
• Works on both server and browser environments • Works
well with static analysis tools, tree-shakeable Moving to ES Modules
• “You should be able to use a bundler because
you want to, and not because you need to” • Provides unbundled ES Modules that run in the browser • Streaming imports: convert bare imports into CDN imports from Skypack Snowpack
Snowpack Source code Loaded in browser
• Uses native primitives of the Web platform • Relies
on packages being compatible with native ES Modules • Streaming imports: safely import packages from npm or Skypack without installation wmr
wmr Import from npm Import from Skypack
• Opts for ES Modules using absolute or relative URLs,
even for its standard library Deno
Deno Import from npm
Pros in using JS • Easier to contribute to projects
• Rich ecosystem Clearing away legacy assumptions JS tools must be written in JS Pros in using non-JS • Compile to native binaries • Usually faster
• Bundler and minifier written in Go • 10x -
100x faster than JS-based tools
None
• JavaScript / TypeScript compiler written in Rust swc
The Third Age Collapsing layers of tooling One thing doing
many things well, instead of many things doing one thing well
Frontend Decision Fatigue • Animations • Testing • Linting •
Code formatting • Bundling • Frontend framework / library • Client side routing • State management • Form management • Data fetching • Styling
Frontend Metaframeworks
• Whole new runtime • Comes with TypeScript support, linting,
formatting, testing, bundling, and a standard library out of the box Deno
Deno
• Designed to replace Babel, ESLint, webpack, Prettier, Jest, etc.
• Bundling, compiling, docs generation, formatting, linting, minification, testing, type checking, etc. Rome
Rome
• Collapsing everything from reactivity, state management, and animations into
a compiler • No more Virtual DOM layer
None
None
None
Web Development in 2021 and beyond • Faster tools •
Better DX and UX • ES Modules-first • Collapsed layers • More secure
