isDev

Build-time constant that is true in development output and false in production output.

Import

import { isDev } from "@solidjs/web";

const isDev: boolean;

import { isDev } from "@solidjs/web";

if (isDev) {
  console.warn("debug-only path");
}

if (isDev) {
  console.warn("Development-only diagnostic");
}

It is a build-time constant. Code behind if (isDev) is removed from production output.
