fnlock is a module that allows locking on asyncronous functions and queuing of function calls, to be called on release.
npm install fnlock
Simple lock with function call queuing:
var fnlock = require('fnlock');
function run(arg){
fnlock.lock(function(release){
console.log("Enter "+arg);
setTimeout(release,1000);
});
}
run(1);
run(2);
run(3);
It's supposed that the script takes 3 seconds to run.
Setting lock state on a function
var fnlock = require('fnlock');
function run(arg) {
fnlock.lock('run',function(release){
console.log("Enter "+arg);
release();
});
}
fnlock.lock('run');
run('YEY');
setTimeout(function(){ fnlock.unlock('run'); },1000);
It's supposed that the script takes 1 second to run.
