TypeScript 7 in production: a CI migration decision guide
TypeScript 7.0 reached general availability on 8 July 2026 with the Go-native compiler, cutting full builds by 8x to 12x and memory use by up to a quarter on Microsoft's published benchmarks. The release ships without a stable programmatic API until 7.1, which blocks typescript-eslint, framework template checking and Next.js detection, so the right move depends on which of three migration profiles your repo fits.
