Well since you asked so "fuckin" nicely /s if( condition ){ import('../../../hugeFuckingLibraryThatTakesSeveralSecondsToLoadUponColdStart').then( x => { //do something with x }) } > ...nerd bullshit... I hate to break it to you darling, but programming is nerd bullshit. edit: alternate that might too much "nerd bullshit", but uses async/await if the surrounding code is an async function: async function doSomeStuff() { if( condition ){ const x = await import('../../../hugeFuckingLibraryThatTakesSeveralSecondsToLoadUponColdStart'); //do something with x } }
