TypeScript 7.1 beta restores compiler API and introduces content mappers
Go-native compiler update brings up to 4.6x speed gains and a content-mapper path for Vue and Svelte, but a reported stale-types issue remains open
Microsoft has released TypeScript 7.1 Beta, an update that restores the programmatic compiler API dropped in TypeScript 7.0 and introduces content mappers for virtual views of non-standard files such as Vue and Svelte components. A hands-on migration write-up reports type-checking speed improvements of up to 4.6 times.
