Answer 1

Typescript where to find typings

Its all about the compilation context. (more). If a file makes it into the context then it is analyzed.

Ways a file can make it in

• Its in the files
• Its in the filesGlob and you are using something that understands filesGlob (e.g. atom-typescript, alm, grunt-ts)
• Its referenced (i.e. <reference path=) by a file that already made it into the compilation context
• Its imported (i.e. import foo = require('./foo') etc) but a file that already made it into the compilation context.
• You passed it in on the command line.
• It is a lib file (e.g. lib.d.ts)

Etc.

Additionally file might be global or a module (more).
