Without @types/node, every program loaded scriptc-node-fallback.d.ts whole: the console and process globals and 47 Node modules, about 8,100 lines, parsed, bound and checked in every cold build whether or not the program imported them. - The fallback file keeps the globals and the modules they name (console, readline, readline/promises, perf_hooks, tty). Every other module, under both spellings, has its own file in ambient/node-fallback/, which references the files of the modules its declarations name. - A module's file joins the program when one of the program's files names the module in a string literal: imports, requires, import types and JSDoc types all name modules that way. The entry is read before the first program; the program-root discovery passes add modules that other files name. Files are read as tsgo reads them, and the TypeScript libraries and scriptc's own declarations are skipped. - The checks that recognized the fallback file by its path recognize every fallback file.

/* node:string_decoder — StringDecoder over Node's whole encoding set:
|
|
* write() decodes complete sequences and buffers a trailing partial one
|
|
* across chunk boundaries (utf8's truncated sequence, base64's mod-3
|
|
* remainder, utf16le's odd byte / trailing lead surrogate; latin1, ascii
|
|
* and hex are stateless); end() flushes the buffered partial. `encoding`
|
|
* answers the normalized name. Node's exact algorithms (SEMANTICS.md);
|
|
* the encoding must be a literal, and end(buffer) fences — write the
|
|
* buffer, then end(). */
