The proxy patch in node_modules is lost on every fresh npm install. This postinstall script automatically patches @polymarket/clob-client http-helpers to inject HttpsProxyAgent for all polymarket.com requests. Runs automatically after npm install — no manual patching needed on VPS deploy. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

|
* patch-clob-client.cjs
|
|
*
|
|
* Patches @polymarket/clob-client to inject proxy support.
|
|
* Runs automatically via `npm install` (postinstall hook).
|
|
*
|
|
* What it does:
|
|
* - Adds HttpsProxyAgent import to http-helpers/index.js
|
|
* - Injects proxy agent into every axios request to polymarket.com
|
|
* - Reads PROXY_URL from process.env at runtime
