AppErgo's answer:
AppErgo was created in France in 2026 as an independent project developed by a solo creator. Its name combines โAppโ, for applications and online tools, with โErgoโ, reflecting a focus on ergonomics, simplicity and ease of use. The project started with a small collection of practical tools and gradually grew into a toolbox of more than 200 tools covering text, codes and puzzles, dates, audio, games and everyday tasks.
AppErgo's answer:
AppErgo is primarily built with static HTML, CSS and vanilla JavaScript. Its pages are generated through a custom administration system based on PHP and MySQL, while the public tools rely on standard browser technologies such as SVG, Canvas and the Web Audio API. All processing takes place directly in the browser, without external APIs or remote processing services.
AppErgo's answer:
AppErgo is designed for students, teachers, developers, creators, office workers, puzzle enthusiasts and everyday users who need a practical online tool without creating an account or navigating a complicated service.

Yes, in the Monaco editor (https://microsoft.github.io/monaco-editor/). It's not just typechecking, the typescript library is also the reference parser for TypeScript and reference emit. Emitting TypeScript is non-trivial and non-local. It's not just in browsers, you might want to run the typescript library on the edge or in some restricted environment where JS/WASM is OK but native code is not. You may want to... - Source: Hacker News / 24 days ago
So I switched to Monaco editor, the same editor that powers VSCode. The extension instantly became a few MB heavier, but it was definitely worth it. Monaco editor was extremely powerful, with all the standard editor features such as renaming variables, syntax highlighting, and more just out of the box. I'm so glad I didn't have to implement any of that myself, yet it's available for everyone to use. - Source: dev.to / 4 months ago
I have yet to see a good web based text editor with syntax highlighting. I slightly expect you to pull a "no true Scotsman" here and suggest it's actually no good because it doesn't really support mobile browsers very well, but Microsoft's Monaco editor that's driven from VS Code is quite good. https://microsoft.github.io/monaco-editor/. - Source: Hacker News / 8 months ago

It also uses WebGL + canvas rendering to show minimap of the file. Similar approach (custom virtual processor) is leveraged by Google docs/sheets. Canvas... - Source: Hacker News / about 2 years ago
