blocking-style
Allows synchronous coding style in JavaScript
Installation
npm install blocking-style --save
Example usage
require('blocking-style');
...
const {onexit, blocking, wait, prompt} = require('blocking-style');
onexit(function()
{
console.log("this function called when main finishes");
});
//main function:
blocking(function*()
{
console.log("start");
var response = yield prompt("Waits here until something entered ...");
console.log("you entered '%s'", response.replace(/\n/, "\\n"));
for (var i = 0; i < 10; ++i)
{
console.log("wait");
yield wait(1); //pause 1 sec
}
console.log("done");
});
Main function will wait synchronously for events such as keyboard entry or timer.
Internally the code is still asynchronous, but a generator function can be used to allow the code to be structured with a synchronous, blocking code style like in other languages. This can make the code easier to read, rather than using a bunch of callback functions.
See test/test.js for an example.
