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.
