typeOf
When you are not sure about the type, determine the type it belongs to includes
- string
- object
- array
- number
- null
- undefined
- regex
- date
// typeOf
Console.log(T.typeOf(Symbol("a")));
Console.log(T.typeOf(new Date()));
Console.log(T.typeOf(undefined));
Console.log(T.typeOf(null));
// symbol at Object.<anonymous> (/examples/test.ts:39:9)
// date at Object.<anonymous> (/examples/test.ts:40:9)
// undefined at Object.<anonymous> (/examples/test.ts:41:9)
// null at Object.<anonymous> (/examples/test.ts:42:9)
Time
Y => Year, M => Month, D => Date, h => hour, m: minutes, s: seconds.
console.log(Time.datefmt(new Date())); // default
// 2022/11/14 15:42:20
console.log(Time.datefmt(new Date(), "D-m")); // change fmtPattern
// 14/45
console.log(Time.datefmt(new Date(), undefined, ":*")); // change fmt modifer
// 2022:11:14 15*47*13
Timer
let bubbleCount = 0;
const timerFn = (...args) => {
Console.log("bubble count", ++bubbleCount);
Console.log("params", args);
};
let testTimer: undefined | NodeJS.Timer;
const NOW = Date.now();
const debounceImplFn = Timer.debounce(timerFn, 1000);
const throttleImplFn = Timer.throttle(timerFn, 600);
testTimer = setInterval(() => {
if (Date.now() - NOW > 3000) {
clearInterval(testTimer);
testTimer = undefined;
}
debounceImplFn("debounce", "foo");
throttleImplFn("throttle", "bar");
}, 16);
// bubble count 1 at timerFn (/examples/test.ts:41:10)
// params [ 'throttle', 'bar' ] at timerFn (/examples/test.ts:42:10)
// bubble count 2 at timerFn (/examples/test.ts:41:10)
// params [ 'throttle', 'bar' ] at timerFn (/examples/test.ts:42:10)
// bubble count 3 at timerFn (/examples/test.ts:41:10)
// params [ 'throttle', 'bar' ] at timerFn (/examples/test.ts:42:10)
// bubble count 4 at timerFn (/examples/test.ts:41:10)
// params [ 'throttle', 'bar' ] at timerFn (/examples/test.ts:42:10)
// bubble count 5 at timerFn (/examples/test.ts:41:10)
// params [ 'throttle', 'bar' ] at timerFn (/examples/test.ts:42:10)
// bubble count 6 at timerFn (/examples/test.ts:41:10)
// params [ 'debounce', 'foo' ] at timerFn (/examples/test.ts:42:10)
DataUtils
- String generate random string, default len: 16
Console.log(Str.rollingRandomString(32));
// bbplbmjpdzmnlujnfvdpufdnhthewkzz at Object.<anonymous> (/examples/test.ts:68:9)
HttpHelper
- uri
- obj2query
const res = HttpHelper.obj2Query({
test: 13,
hh: "tt",
});
Console.log(res);
//?test=13&hh=tt at Object.<anonymous> (/src/dev/HttpHelper.ts:27:9)
ProjectHelper
Use the publish-subscribe model to publish and subscribe to the message bus
const emitter = new EventBus(); emitter.on("foo", (payload) => { Console.log(payload); }); emitter.fire("foo", 123); emitter.fire("foo", 321); // 123 at /src/dev/ProjectUtils/EventBus.ts:38:13 // 321 at /src/dev/ProjectUtils/EventBus.ts:38:13
