Merge with a newer version of TypeScript

Fetch a new release: git fetch upstream
Back to "Updates for tslab" commit: git reset --hard HEAD@{2}
Rebase the commit to the new tag: git rebase -i --onto v3.7.3 v3.7.2 master

Release

Build

npm ci && npm run gulp lint && npm run gulp runtests && npm run gulp LKG && npm run gulp clean

publish

Set the new version in package.json

yarn semver "3.6.4-tslab" -i prerelease --preid tslab

Then, build the compiler and run:

npm publish --access=public

Note that --access=public is necessary because Scoped packages are private by default.

Notes for TypeScript codebase

Files included in typescript.js are defined in src/typescript.ts with import * as ts from "./_namespaces/ts";. For example, when we want to add a new file in src/services, add a reference to the new file in src/services/_namespaces/ts.ts.

TypeScript

TypeScript is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the playground, and stay up to date via our blog and Twitter account.
