Layerr

Errors, with.. layers..

A NodeJS and Web Error wrapping utility, based heavily on VError, but without all the extras and dependencies on Node core utilities. Written in Typescript, compiled to JavaScript and suitable for bundling in the browser.

Installation

Install by running: npm install layerr.

Usage

Use it as a regular error:

const { Layerr } = require("layerr");
 
throw new Layerr("Test error");

Or use it to wrap errors:

doSomething().catch(err => {
    throw new Layerr(err, "Failed doing something");
});

Layerr's can have info attached:

const { Layerr } = require("layerr");
 
function somethingElse() {
    throw new Layerr({
        info: {
            code: 123
        }
    }, "Problem");
}
 
somethingElse().catch((err: Layerr) => {
    const { code } = Layerr.info(err);
    // code === 123
});
