  • Smooth Subtitle Editing Experience. Captioner is built by content creators, for content creators. We spent hours perfecting the editing experience so you can spend more time on your content and less time on the tools.

  • Subtitle File Export. Different platforms and editing softwares use different subtitle file formats. We support the most popular formats (SBV, SRT, VTT) so you can add quickly add subtitles into your YouTube videos. You can also choose a font style directly from the editor and get a video export with the subtitles burned in.

  • What Happens When You Run `npm run dev`
    Vite uses esbuild written in Go, absurdly fast to pre-process your node_modules dependencies. - Source: dev.to / 3 months ago
  • Creating Your First Lambda Function
    The Metadata section tells SAM how to build your TypeScript code. Instead of running tsc and bundling manually, SAM uses esbuild โ€” a JavaScript/TypeScript bundler. It compiles your TypeScript, minifies the output, generates sourcemaps for debugging, and packages it all up. You don't need to install esbuild yourself โ€” SAM handles it during sam build. - Source: dev.to / 3 months ago
  • Claude Code's Source Didn't Leak. It Was Already Public for Years.
    The reality is simple: minification was never security. It's a size optimization that bundlers like esbuild, Webpack, and Rollup do by default. Variable renaming slows down human readers but LLMs read minified code like you read formatted code. - Source: dev.to / 4 months ago
  • How to Minify JavaScript Without Build Tools
    Esbuild is written in Go and is 10-100x faster than JavaScript-based minifiers:. - Source: dev.to / 5 months ago
