strict-ts-lib-v7.0

Strict rewrite of TypeScript 7.0.2's built-in standard library declarations.

npm install -D strict-ts-lib-v7.0

Every built-in library ships inside this one package, in two flavors:

• libs/ — plain number
• libs-branded/ — branded number types (Uint8, SafeUint, …)

Point paths at the one you want, in your tsconfig.json:

{
    "compilerOptions": {
        "libReplacement": true,
        "paths": {
            "@typescript/lib-*": ["./node_modules/strict-ts-lib-v7.0/libs/*"],
        },
    },
}

Two things to watch, because both fail silently — the replacement simply does not happen, with no error:

• paths is replaced, not merged, by a config that extends another, so it has to be written in whichever config TypeScript actually loads.
• The path is relative to the config that contains it, which in a monorepo package is usually ../../node_modules/….
