Documented steps
Define your main script in the scripts field, for example "build": "tsc".
Add sibling scripts named prebuild and postbuild; npm runs them automatically whenever you invoke npm run build in the order prebuild -> build -> postbuild.
Run npm run build and watch stdout: npm prints each script name as it fires, confirming the pre/post chain.
The pre/post auto-run applies to every arbitrary script and to built-in commands (npm test, start, stop, restart).

Known gotchas
Calling npm run prebuild directly re-invokes its own pre/post chain, which can recurse unexpectedly; rely on npm to trigger hooks.
Arguments after -- are forwarded only to the named script, never to its pre or post siblings.
A non-zero exit in any pre/script/post step stops the chain immediately.
