TypeScript 7 — Nooc Cusub oo 10x Dhaqso Badan TypeScript 6

TypeScript 7

TypeScript 7 waa release-ka ugu weyn ee taariikhda TS laga soo daayay, kaas oo si buuxda dib loogu qoray luqadda Go (Project Corsa). Waxaa la sii daayay July 8, 2026.

Farqiga ugu weyn ma aha oo keliya features cusub — waa performance. Compiler-kii hore wuxuu ku dhisnaa JavaScript, halka kan cusubi u tahay native code oo isticmaala shared memory multithreading, taasoo keentay speedup u dhaxaysa 8x ilaa 12x marka la sameeyo full build.

Isbarbardhiga TS 6 iyo TS 7

Fikradda ugu wanaagsan ee lagu fahmi karo farqigu waa figures-ka dhabta ah ee VS Code laftiisa lagu benchmark-gareeyay:

Build Time

Version	Waqti
TypeScript 6	125.7s
TypeScript 7	10.6s
Speedup	~11.9x

Memory Usage

Version	Memory
TypeScript 6	5.2GB
TypeScript 7	4.2GB
Dhimis	18%

Codebases waaweyn oo kale ayaa sidoo kale si dhaqso ah loo type-check-gareeyay:

• Sentry — 1.9 million lines of code, 15.7s gudahood
• Bluesky — 628,000 lines, 2.8s
• Playwright — 528,000 lines, 1.47s

---

Maxaa Cusub:

• Type checker parallelization — type-checking oo la kala qaybiyo threads badan
• Project reference builder parallelization
• Watch mode oo la hagaajiyay — rechecks-ka watch-ka hore ka dib waxay qaataan ilaa hal second oo keliya
• Defaults cusub: strict: true, module: esnext
• Editor tooling oo lagu dhisay Language Server Protocol (LSP) — 20x dhimis ah oo ah language server commands-ka fail-ga ah

---

Fursadaha Cusub (New Opportunities)

Speed-ka cusubi wuxuu bedelayaa developer workflow-ga:

• Feedback degdeg ah — errors, auto-imports, iyo go-to-definition oo isla markiiba shaqeeya. Ma jirto sugid daqiiqado ah oo lagu load-gareeyo tsconfig project-ka.
• Large-scale projects — monorepos, banking systems, iyo enterprise apps oo hadda si macquul ah loo maareeyo.
• CI/CD pipelines oo si dhaqso ah u dhammaada — waqti iyo kharash badan oo yaraan doona.

Breaking Changes — Ka hor Upgrade-ka

Isbeddellada muhiimka ah ee laga yaabo inay Cilad ku keenaan project-kaaga:

• target: es5 waa la removed-gareeyay, sidoo kale downlevelIteration
• moduleResolution: node/node10/classic waxaa lagu replace-gareeyay nodenext iyo bundler
• baseUrl waa la removed-gareeyay — isticmaal paths oo relative ah
• esModuleInterop iyo allowSyntheticDefaultImports oo false ah lama allow-gareeyo

Talo: Waxaad side-by-side u run-gareyn kartaa version-ka hore iyo kan cusub adigoo isticmaalaya package-ka @typescript/typescript6, ilaa stable APIs-ka TS 7.1 la keeno.

⚠️ Ogow: Stable programmatic API-gu ma iman doono ilaa TS 7.1, mana jiro webpack loader API weli — taas oo saameyn ku yeelan karta tooling qaarkood.

Nala wadaag haddii caqabad kala kulantahay ama si fiican uu kuugu shaqeeyay.
