simple-fullstack-examples VS graceful-fs

Barring that, maybe take a look at this example here, it's not my code (and I just glanced at it briefly) but it seems to be a pretty basic example of how things generally work. Basically it contains a node app and the entry-point for that is src/index.js so take a look at that file and see how it's running a web service and connecting to a database, these are things that can (for our current purposes) only be done on the backend with the node app.

async (config?: { /** * Overwrite the default ignored behavior */ customIgnored?: string[]; }) => { const projectRoot = getProjectRoot(); if (!projectRoot) return; // NB: fix to globally alter real fs in order to fix EMFile error that happens in TSMorph (see https://github.com/isaacs/node-graceful-fs) gracefulFs.gracefulify(realFs); console.log("Searching..."); const tsFunctions = await db.get("TsFunction"); const projectWatcherTsFunctions = tsFunctions.filter( (x) => x.explicitTypeName === "ProjectWatcher" ); const projectWatchers = projectWatcherTsFunctions .map((x) => x.name) .map((name) => sdk[name as keyof typeof sdk] as ProjectWatcher | undefined) .filter(notEmpty); log(`${projectWatchers.length} watchers gonna watch ${projectRoot}`, { type: "important", }); const startupWaitMs = 1000; setTimeout(() => { log( `There they are! \n\n${projectWatchers .map((projectWatcher) => { return `👁 👁 ${projectWatcher.name} ✅`; }) .join("\n")}`, { type: "success", } ); }, startupWaitMs); const startTimeAt = Date.now(); watch(projectRoot, { ignoreInitial: true, ignored: config?.customIgnored || [ "**/node_modules/**", "**/.next/**", "**/.expo/**", "**/build/**", "**/db/**", "**/.git/**", "**/.turbo/**", "**/generated/**", ], // alwaysStat: true, // not sure why I would need this, seems inefficient if I don't need it, I can simply run fs.stat }).on("all", (eventName, path, stats) => { if (Date.now() < startTimeAt + startupWaitMs) return; const relevantWatchers = projectWatchers.filter((watcher) => watcher.filter(eventName, path) ); oneByOne(relevantWatchers, async (projectWatcher) => { await projectWatcher(eventName, path); }); }); };

What's probably got your shorts in a knot is the contents of the node_modules directory. That directory is a cache for mode.js modules so the tutorial can function standalone without having to install anything else. Treat it as you would object code. I pulled a half-dozen of those modules at random and went to their repositories. Every one of them had unit tests: block-stream, graceful-fs, lowercase-keys, minimist, pify and safe-buffer. Nobody sane ships unit tests with their executables.
