package.json `exports` field not working with TypeScript

It has finally become available in Typescript 4.7

Your library:

// package.json
"exports": {
  ".": "./dist/index.js",
  "./svg": "./dist/svg.js",
  "./html": "./dist/html.js",
  "./package.json": "./package.json"
},

Your client code must have:

// tsconfig.json
"compilerOptions": {
  "moduleResolution": "node16" // or "nodenext"
}

Prior to Typescript 4.7 you could utilize typesVersions:

// package.json
"main": "dist/index.js",
"types": "dist/index.d.ts",
"exports": {
  ".": "./dist/index.js",
  "./svg": "./dist/svg.js",
  "./html": "./dist/html.js",
  "./package.json": "./package.json"
},
"typesVersions": {
  "*": {
    "svg": ["dist/svg.d.ts"],
    "html": ["dist/html.d.ts"]
  }
}
