Documentation for all runtime functions (Web APIs + Deno global) can be found
on
doc.deno.land.
For APIs where a web standard already exists, like fetch for HTTP requests,
Deno uses these rather than inventing a new proprietary API.
The documentation for all of these Web APIs can be found on doc.deno.land.
The TypeScript definitions for the implemented web APIs can be found in the
lib.deno.shared_globals.d.ts
and
lib.deno.window.d.ts
files.
Definitions that are specific to workers can be found in the
lib.deno.worker.d.ts
file.
All APIs that are not web standard are contained in the global Deno namespace.
It has the APIs for reading from files, opening TCP sockets, and executing
subprocesses, etc.
The TypeScript definitions for the Deno namespaces can be found in the
lib.deno.ns.d.ts
file.
The documentation for all of the Deno specific APIs can be found on doc.deno.land.
