Tools and workflows—bundlers, dev servers, and compilers like Webpack, Vite, and tsc—that transform and serve JavaScript/TypeScript code.
Redux Toolkit 2.13 adds official TypeScript 7 support and moves to a TSDown build, keeping its APIs unchanged from 2.12. The cost of upgrading is a TypeScript 5.6 floor plus bug fixes that change runtime results in edge cases.
Reality
TypeScript 7.0, the Go-native compiler GA since July, removes the options 6.0 deprecated, so ignoreDeprecations only postponed the break. The audit has to run on 6.0, while tsc still names each option it will drop.

SvelteKit 3.0 requires Node 22.17, TypeScript 6 and Svelte 5.56.4 or newer before any app code changes. Teams have a toolchain project to schedule and ship before they reach the config move and the rewrite of every $lib import.
Reality
Microsoft's Go port of the TypeScript 7 compiler cut VS Code's full build from 125.7 to 10.6 seconds in its benchmarks. Tools that import TypeScript as a library may still need the TypeScript 6 API, so the upgrade belongs on a throwaway branch first.

Anthony Fu's new framework asks devtool authors to define a tool once and mount the result almost anywhere, on the argument that his own six inspectors each rebuilt the same RPC, state sync, serialization and asset hosting.

Running .ts files directly drops tsx and the dist folder, and because the stripper blanks annotations in place instead of deleting them, stack traces stay accurate without a source map. Node still never opens tsconfig.json.

A dev.to write-up traces a failed Hostinger deploy of Next.js 16.3.5 to SWC's native bindings. The fix was an .mjs config file and a --webpack flag on the build script, both committed to the repo, with nothing changed on the host.

The first part of an eight-part deep dive on Native Federation argues that webpack's container runtime is what ties a federated system to one bundler for life, and that ES modules plus import maps cut that tie.

SWC's creator fanned a single instruction out to 45 concurrent Labor0 tasks on the ES minifier, then kept review and merge for himself. He says he does not know how long the run took; he was looking at his phone.

enableWorker defaults to true and stays true when no worker exists, so the config that looks right proves nothing. One line of resource timing tells you which thread is actually doing the transmux.

A GSoC project rebuilt webpack's API docs as a pipeline that regenerates from TypeScript declarations on release. The awkward part was getting one repo to trigger another.

Vite fixes the build times and the config cliff that retired Create React App, and keeps the client-only rendering. Next.js fixes that, and charges for it.
