exec(command, callback) and exec(command, { encoding, maxBuffer },
callback) lower like execFile's callback slice. The command line runs
with /bin/sh -c, as execSync runs it, the call returns the live
ChildProcess, and the error-first callback receives the captured utf8
stdout and stderr. A non-zero exit, including the shell's 127 for a
missing command, reports Node's "Command failed: <command>\n<stderr>":
scr_exec_file takes a shell flag so the message shows the command line.
Under @types/node, child_process.ExecException maps to Error, as
ExecFileException does. Its code member is the child's numeric exit
status, which the runtime error's string code slot does not hold, so
reading it, testing it with `in`, or testing its typeof is a named
refusal.
node-types fixture
A project whose node_modules contains @types/node — the adoption path for real-world Node/TypeScript projects. The vendored node_modules are COMMITTED TEST DATA, pinned so the type surface (and therefore the pinned diagnostics) never drifts with the registry:
@types/node24.13.3undici-types7.18.2 (its dependency — declares the web-platform globals: fetch/Response/AbortSignal/ReadableStream/...)
What the fixture pins (see tests/harness/project-config.test.ts):
argv-env.ts— the SUPPORTED process surface (argv, env) typed by @types/node lowers statically and the binary runs: with @types/node present, the shipped fallback declarations forprocess/node:fs/consolestand down (their types come from @types/node), but the same members lower to the same libCalls, recognized by name + @types/node provenance.fenced.ts— surface @types/node DECLARES but scriptc does not lower (process.uptime, Buffer.from, setInterval) reports the SC2020-family fence naming @types/node, instead of typechecking its way into a broken binary — and never a raw "Cannot find name" error.source-import/— an imported TypeScript source may use theRequestInfoglobal supplied by TypeScript's default DOM lib while scriptc adopts the project's @types/node declarations.
Projects WITHOUT @types/node (every other fixture and the whole corpus) keep the shipped fallback declarations and behave exactly as before.
