debug VS cosmiconfig

Another way to solve this is to have the logs in place, but only enable them conditionally. If you enable all the logs are the time, you only get a lot of noise that won't help you. If you are using JavaScript, you can use the package debug to add logs that are active by the DEBUG environment variable.

I'm using the debug package: https://www.npmjs.com/package/debug, but some reason I don't see millisecond diffs, which would be really useful.

Although it's used by Express, it's indeed more broadly, the way a popular NPM package called debug works, which is used internally in Express too. Under the hood, the debug package expects the DEBUG environment variable to determine what debug messages to print (could be on the console, or into a file, or into stdout to be collected by a log aggregator service).

Finally, if they're logs you want to be able to inspect in production without printing them to the console by default, you can use debug.

It is a drop-in, TypeScript replacement to enhance the widely popular https://www.npmjs.com/package/debug (230k weekly downloads).

debug - npm - Required. A popular library to write debug logs.

I strongly recommend using the debug package from NPM to organize your log messages

Use the [debug npm library](https://www.npmjs.com/package/debug) to disable your logging unless someone provides the right environment variable (e.g. DEBUG=* which enables all logging)

A lot of tools rely on the NODE_ENV environment variable for that, React included. Another great package that’s pretty popular is https://www.npmjs.com/package/debug You can create namespaces and then filter the logs you are interested in.

Meanwhile, formats have been evolving (JSON5, YAML), config entry points are constantly changing. These fluctuations, fortunately, were covered by tools like the cosmiconfig.

I've heard of cosmicconfig, which I think allows you to put most of your config files in a single .config folder. I've never used it though.

There is a fantastic library davidtheclark/cosmiconfig: Find and load configuration from a package.json property, rc file, or CommonJS module that does all the tedious work for you.

info on XDG: [the XDG spec](https://standards.freedesktop.org/basedir-spec/basedir-spec-...)

tools that respect XDG, for fellow JS CLI developers:

- https://github.com/davidtheclark/cosmiconfig Find and load configuration from a package.json property, rc file, or CommonJS module. [Check `searchPaths` to implement XDG spec compliance.](https://github.com/davidtheclark/cosmiconfig/issues/152)

- Sindre's libraries use [`env-paths`](https://github.com/sindresorhus/env-paths#pathsconfig) to get paths compliant with this.

- https://github.com/sindresorhus/conf simple config storing (maybe try [conf-cli](https://github.com/natzcam/conf-cli) to manipulate if needed) the successor to [configstore](https://github.com/sindresorhus/conf#how-is-this-different-f...)

- https://github.com/jonschlinkert/data-store conf like datastore but in the shclinkerverse

cosmiconfig - Reads configuration from a file. It searches for many file types and file names, and even supports defining config in the package.json file. Very customizable, it's an awesome library very flexible both for the app developer and for the app user.
