Simple and best solution in wordpress/env(wp-env) development

By Fumiki Takahashi (Takahashi_Fumiki) on July 10, 2025

If you have troubles in local development with wp-env, use this plugin.

In your .wp-env.json , add this plugin's download URL(NOTICE: review comment is not allowed to include URL, add https +:// just before the downloads.wordpress.org

{
    "plugins": [
        ".",
        "[schema here]downloads.wordpress.org/plugin/localhost2host-docker-internal.latest-stable.zip"
    ]
}

WordPress' self remote request(e.g. WP-Cron) starts working as expected! Arigato!
