Including built-in type declarations with —lib

Getting to ES6/ES2015 built-in API declarations were only limited to target: ES6.Enter —lib; with —lib you can specify a list of built-in API declaration groups that you can chose to include in your project.For instance, if you expect your runtime to have support for Map, Set and Promise (e.g. most evergreen browsers today), just include —lib es2015.collection,es2015.promise.Similarly you can exclude declarations you do not want to include in your project, e.g. DOM if you are working on a node project using —lib es5,es6.

Here is a list of available API groups:

• dom
• webworker
• es5
• es6 / es2015
• es2015.core
• es2015.collection
• es2015.iterable
• es2015.promise
• es2015.proxy
• es2015.reflect
• es2015.generator
• es2015.symbol
• es2015.symbol.wellknown
• es2016
• es2016.array.include
• es2017
• es2017.object
• es2017.sharedmemory
• scripthost

Example

tsc --target es5 --lib es5,es2015.promise

"compilerOptions": {
    "lib": ["es5", "es2015.promise"]
}
