Refer to JSR website for installing the package. Or see the instruction above the readme file

Isjsruntime

Update: Full deno support AND bun (that means the engine() function worked!). Updated readme with consistent implementation (because of the old repo). And now the script is typesafe!

Only contains 2 non-async function (which on fails, return undefined)

• env(legacy=false) for detecting javascript runtime. Contains one optional parameter (boolean) for enabling the legacy detector for JSDOM, and
• engine() for detecting javascript engine. No parameters required

And 2 types

• jsEngineList list of accepted engine such as v8, etc.
• jsEnvList list of accepted javascript runtime

Detect if running on bun (working with/without polyfill)

// import the package
import * isjs from '@cupglassdev/isjsruntime'
// make a function
function run(){
// check using the env() function
const env = isjs.env()
if (env==='bun'){ 
  console.log('you are on bun')
} else {
  throw new Error('it looks like you are using another js enviroment')
}
}
// run the function
run()

detect if the node engine is running on v8

import * as isjs from '@cupglassdev/isjsruntime'

function isusingv8() {
// check using the engine() function
const engine = isjs.engine()
if (engine ==='v8') return true
else return false;
}
//print it onto the console
console.log(isusingv8())
