General information

This is a plugin for Insomnia that allows you to write dynamic variables that reference other environment variables that you've defined.

This is especially useful if you want to conditionally modify things like your API_URL.

An exact use case would be if you have a proxy that forwards in the format of https://myproxyurl.com/?url=https://myrealapiurl.com/v1/action

Installation

Install the insomnia-plugin-evaljs plugin from Preferences > Plugins.

Usage

Add EvalJS to your desired environment variable (hit Ctrl + space to open tags) and put your js code in the Code snippet input

Examples

env.OTHER_VARIABLE ? 'i am true':'i am false'

env.USE_PROXY && env.PROXY_URL ? `${PROXY_URL}${API_URL}`:${API_URL}

(function() { const iife='hello world'; return iife; })();

(function() {
    const items = ['one', 'two', 'three'];
    return items.join("");
})();
