@pygy/dev-mode v1.0.0

dev-mode.js

A pair of devMode/production booleans, and matching setters.

usage

import {devMode, production} from "@pygy/dev-mode"

if (devMode) {
    // extra checks go here
}

if (production) {
    // logging instrumentation
}

You can dynamically change the values using

import {setDevMode, setProduction, devMode, production} from "@pygy/dev-mode"

// in a default env:
console.log(devMode, production) // true, false

setProduction()

console.log(devMode, production) // false, true

setDevMode()

console.log(devMode, production) // true, false

In Node.js, these values will be swapped when NODE_ENV=production.

For your client-side production builds, you can statically replace @pygy/dev-mode with @pygy/dev-mode/production in your bundler parameters. That file sets the booleans in a way that lets minifiers statically remove the dev code. In that case, the setters are no-ops.

import {setDevMode, setProduction, devMode, production} from "@pygy/dev-mode/production"

console.log(devMode, production) // false, true

setProduction()

console.log(devMode, production) // false, true

setDevMode()

console.log(devMode, production) // false, true
