Installing External Packages

import reflex as rx

Reflex Build allows you to install external python packages to use in your app. This is useful if you want to use a package that is not included in the default Reflex Build environment. Examples might include openai, langsmith, requests, etc.

There are two ways to install external packages:

1. Through the Chat Interface: You can ask the AI to install a package for you.
2. Add to the requirements.txt file: You can add the package to the requirements.txt file and then save the app. This will install the package in your app's environment.

Installing through the Chat Interface

Enter the name of the package you want to install in the chat interface. The AI will then install the package for you.

rx.el.div(
    rx.image(
        src="https://web.reflex-assets.dev/ai_builder/external_packages_input.avif",
        class_name="rounded-md h-auto",
        border=f"0.81px solid {rx.color('slate', 5)}",
    ),
    class_name="w-full flex flex-col rounded-md",
)

Installing through the requirements.txt file

Add the package to the requirements.txt file and then save the app. This will install the package in your app's environment and recompile your app.

rx.el.div(
    rx.image(
        src="https://web.reflex-assets.dev/ai_builder/external_packages_requirements.avif",
        class_name="rounded-md h-auto",
        border=f"0.81px solid {rx.color('slate', 5)}",
    ),
    class_name="w-full flex flex-col rounded-md",
)
