runtime-context

There are situations where browser support and server support never even tried getting on the same page. (ex: consider that URL paths all use unix separators, while file: urls use platform specific paths and node.js URLs uses both file: paths (but with a different interaction pattern) and native paths. In addition most of the places you have access to poll are standard locations which are the same from platform to platform.

Essentially the standards bodies invent something new every time the problem appears.

Imagine how much simpler node would have been with all posix paths and virtual locations for platform specific weirdness?

In these situations you need specific detail about what the running scenario is. That's what this module does. In addition it fixes some logic to make server and client OS detection symmetrical and augments the detect-browser code (Ex: it detects no less than 13 versions of windows yet cannot differentiate linuxes or even identify MacOS).

Usage

import { 
    isBrowser, 
    isNode, 
    isWebWorker, 
    isJsDom, 
    isDeno,
    isBun,
    isClient, // is running a client
    isServer, // is running on a server runtime
    variables, // global variables
    isLocalFileRoot, // run within a page using a file: url
    isUrlRoot, //run within a page with a served url
    isServerRoot, //run within a 
    os, // Operating system, machine friendly
    operatingSystem, // Operating System, label
    runtime // server runtime name or browser name
} from '@environment-safe/runtime-context';

Testing

Run the es module tests to test the root modules

npm run import-test

to run the same test inside the browser:

npm run browser-test

to run the same test headless in chrome:

npm run headless-browser-test

to run the same test inside docker:

npm run container-test

Run the commonjs tests against the /dist commonjs source (generated with the build-commonjs target).

npm run require-test

Development

All work is done in the .mjs files and will be transpiled on commit to commonjs and tested.

If the above tests pass, then attempt a commit which will generate .d.ts files alongside the src files and commonjs classes in dist
