Environment Variables

1. Shared State

This feature is only available on macOS 10.15+. Prior to macOS 10.15, it might be crashed.

It's possible to share states from the onRequest() and the onResponse() from different scripts when the script is executed with the global object: sharedState

• The sharedState is a JS Object (Dictionary), so you can assign any keys and values from onRequest(), then receive the data on the onResponse() or from different scripts.

The following code demonstrates:

• Get the global counter and increase it as soon as the script is executed

• Share data between Request and Response

function onRequest(context, url, request) {

  // Save some state to sharedState
  sharedState.url = url;
  sharedState.data = "custom";
  sharedState.info = {"username": "Proxyman"};
  
  // Increase the global counter
  var count = sharedState.count ?? 0;
  count += 1;
  sharedState.count = count;
  
  // Log
  console.log(sharedState);
  return request;
}

function onResponse(context, url, request, response) {

  // Receive it
  console.log("Custom data = " + sharedState.dataa);
  console.log("sharedState.count = " + sharedState.count);
  
  // Done
  return response;
}

From Proxyman 2.25.0+, the sharedState is available across different scripts. It is only released when quitting Proxyman app or using `clearSharedState()` function.

Prior to Proxyman 2.24.0, the sharedState is only alive on the current flow that executes the script and it's released when the script is run over.

To clear all data, please consider using `clearSharedState` function.

// Clear all data from sharedState object
clearSharedState();

2. Environment Variables

Environment Variables feature is introduced from Proxyman 3.8.0 and later.

• Scripts can access system env.

• Support bash or zsh.

How to use

1. Define an env in your ~/.zshrc or ~/.bashrc

export ACCESS_TOKEN=AAABBBCCC
export PROXYMAN_PATH=/Users/my_user/Desktop/file-mapper

2. Open any scripts -> More button -> Environment Variables -> Allow all scripts to access env.

3. Reload the ENV to get the env update.

Enable env on scripts

4. Access env from your script with a prefix $

async function onResponse(context, url, request, response) {
  console.log($PATH);
  console.log($ACCESS_TOKEN);
  console.log($PROXYMAN_PATH);
 
  // Done
  return response;
}

3. Additions

• Manually Reload the System Env (Available on Proxyman macOS 4.15.0 or later). Make sure we enable the permission first, in the More Button -> Environment Variables -> Allow all scripts to read env.

async function onRequest(context, url, request) {
  // manually reload to get the latest changes
  _reloadEnv();
  
  // get env
  console.log($PROXYMAN_ID)
  
  // Done
  return request;
}
