Utils

npm install @bahatron/utils

A collection of utility functions and objects

Logger

Fast and simple event driven logger.

import { Logger } from "@bahatron/utils";

const logger = Logger.Logger({
    id: "myLogger",
    pretty: false,
    debug: true
})

logger.on("error", async (entry) => {
    // doSomething
})

logger.warning({foo: "bar", "this is a warning")

Helpers

getenv

get env will throw an exception if MY_ENV_VAR is not set and there's no default value. This is good for failing fast

import { Helpers } from "@bahatron/utils";

let val = Helpers.getenv("MY_ENV_VAR", "aDefaultValue");

parallelize

Parallelize the work of a queue of item around a number of workers. This is done through promises on the main thread rather than using child processes Great for funnelling http calls

let httpCallsToMake = [...]

await parallelize({
    workers: 100,
    queue: httpCallsToMake,
    handler: async (item) => {
        // doYourThing
    }
})

Validator

import { Validator } from "@bahatron/utils";

let errors = Validator.json(MyObject, MyJsonSchema);

let maybeString = Validator.optionalString(null); // undefined

let maybeInt = Validator.optionalInt("12"); // 12

let maybeInt = Validator.optionalInt("abc"); // undefined

Usage no npm install needed!
