Angular 1 de 5, React 4 de 5 · React à frenteQuanto há para ler, e quanto disso pertence a outra pessoa.AngularReactLines of code (TodoMVC)307312Angular está 1.6% abaixo de ReactFewer lines to read when someone else picks the project up. Counts the code you write and maintain yourself, not a stylesheet you installed from npm.Official TodoMVC implementation from github.com/tastejs/todomvc, plus the $mol one from the todomvc-compare repository. Every line of every source file under `src/`, tests, build config and the HTML shell excluded. Styles are excluded for every framework, because TodoMVC renders one fixed layout and its CSS is the same work regardless of framework: the tastejs examples install that stylesheet as the `todomvc-app-css` package and keep a small override sheet, while the $mol implementation writes its own. Counting styles would compare that packaging choice rather than the frameworks. The counting rule is the one published in todomvc-compare and reproduces its $mol figure to the line.Angulargithub.com/…/angular2026-08-13Reactgithub.com/…/react2026-08-13npm packages shipped63React está 50% abaixo de AngularHow many npm packages end up inside the bundle the browser downloads.

Unlike the line count, styling is included everywhere and is comparable: the shared `todomvc-app-css` is compiled into each tastejs example’s shipped CSS, and $mol compiles its styles into the JavaScript bundle, leaving its `web.css` a 38-byte comment. The `base.js` page furniture from `todomvc-common` is excluded everywhere, including its Angular equivalent.

Como isto é medido
Cada valor aqui vem de uma medição ou de uma fonte externa, e carrega consigo o link e a data em que foi tirado. Uma métrica conta para uma categoria só quando os dois frameworks a publicam: caso contrário, aquele com a tabela mais completa venceria pelo tamanho dos seus dados e não pelo que os números dizem. Onde ninguém mediu ainda, a linha diz isso em vez de chutar.Metodologia e fontes no GitHub
