Does the README Provide Installation Instructions for pi-web?

Yes, the README in the agegr/pi-web repository contains comprehensive, step-by-step installation instructions for π-Web, covering both temporary execution via npx and permanent global installation via npm.

The agegr/pi-web repository distributes π-Web as a Node.js-based web tool. According to the source code, the README.md file serves as the primary documentation, providing exact commands and configuration details needed to install, run, and uninstall the application.

Installation Methods Documented in the README

The README outlines two distinct approaches to running π-Web, allowing users to choose between immediate execution or a permanent system installation.

Running Without Installation (npx)

For users who prefer not to install the package permanently, the README documents a "Quick Start" method using npx. This approach fetches the latest version directly from the npm registry and starts the server immediately.

As detailed in lines 13-27 of README.md, execute the following command:

# Fetch the latest version from npm and start the server immediately

npx @agegr/pi-web@latest

This command temporarily downloads and executes the package without adding it to your global npm packages, making it ideal for testing or occasional use.

Global Installation (npm install -g)

For frequent use, the README recommends installing π-Web globally. This approach adds the pi-web command to your system path, enabling you to launch the server from any directory.

The installation command documented in the README is:

# Install or upgrade to the latest version

npm install -g @agegr/pi-web@latest

# Start the server (the `pi-web` command is now available globally)

pi-web

Once installed, the CLI entry point in bin/pi-web.js handles command parsing and server initialization. The package name @agegr/pi-web is defined in package.json, which the npm CLI references during installation.

Managing Your Installation

The README also includes instructions for removing a global installation. To completely uninstall π-Web from your system, run:

npm uninstall -g @agegr/pi-web

This command removes the package and the global pi-web command from your environment.

Launching and Configuring the UI

Once the server starts, π-Web serves its interface through a local development server. The README specifies the default network address and startup behavior options.

Default Server Address

After installation and startup, navigate to the following address to access the UI:

http://127.0.0.1:30141

This URL serves the root Next.js page defined in app/page.tsx, which renders the main web interface.

Disabling Automatic Browser Launch

As documented in lines 43-49 of README.md, you can prevent the browser from automatically opening when the server starts:

• Use the --no-open flag: pi-web --no-open
• Set the environment variable: PI_WEB_NO_OPEN=1

The bin/pi-web.js file processes these flags to modify the startup sequence accordingly.

Summary

• The agegr/pi-web README provides complete installation instructions for π-Web in lines 13-27 of README.md.
• Users can run the tool temporarily via npx @agegr/pi-web@latest or install it globally using npm install -g @agegr/pi-web@latest.
• Global installations are removed with npm uninstall -g @agegr/pi-web.
• The server defaults to http://127.0.0.1:30141, with the UI rendered by app/page.tsx.
• Startup behavior can be controlled via the --no-open flag or PI_WEB_NO_OPEN environment variable, as detailed in lines 43-49 of the README.

Frequently Asked Questions

Does the README explain how to install pi-web globally?

Yes, the README provides explicit instructions for global installation using npm install -g @agegr/pi-web@latest. After installation, the pi-web command becomes available system-wide, and the CLI entry point in bin/pi-web.js handles subsequent server launches.

Can I run pi-web without installing it permanently?

Yes, the README documents a temporary execution method using npx @agegr/pi-web@latest. This command downloads and executes the latest version without adding the package to your global npm installation, which is useful for testing or one-time use.

Where does the README specify the server address and startup options?

The README indicates that the server runs on http://127.0.0.1:30141 by default. Lines 43-49 of README.md document the --no-open CLI flag and PI_WEB_NO_OPEN environment variable for controlling browser auto-launch behavior.

What package name does the README use for installation commands?

The installation commands reference the scoped package name @agegr/pi-web, as defined in package.json. Both the npx and npm install commands use this exact name to fetch the correct repository from the npm registry.
