deprecation

Log a deprecation message with stack

Usage

Browsers	Load deprecation directly from cdn.pika.dev <script type="module"> import { Deprecation } from "https://cdn.pika.dev/deprecation/v2"; </script>
Node	Install with npm install deprecation const { Deprecation } = require("deprecation"); // or: import { Deprecation } from "deprecation";

function foo() {
  bar();
}

function bar() {
  baz();
}

function baz() {
  console.warn(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}

foo();
// { Deprecation: [my-lib] foo() is deprecated, use bar()
//     at baz (/path/to/file.js:12:15)
//     at bar (/path/to/file.js:8:3)
//     at foo (/path/to/file.js:4:3)

To log a deprecation message only once, you can use the once module.

const Deprecation = require("deprecation");
const once = require("once");

const deprecateFoo = once(console.warn);

function foo() {
  deprecateFoo(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}

foo();
foo(); // logs nothing
