How to Set Up a Private Go Module Proxy

Set the GOPROXY environment variable to your private proxy URL to configure the Go module proxy. This tells the Go toolchain to fetch dependencies from your server instead of the public proxy.

export GOPROXY=https://your-private-proxy.example.com,direct

To make this permanent, add the export command to your shell configuration file (e.g., ~/.bashrc or ~/.zshrc).

Setting up a private Go module proxy tells your Go projects where to download external code libraries. Instead of fetching them from the public internet, your computer asks your company's private server first. It works like a custom library that only your team can access.
