A CLI tool to try Node.js modules instantly without adding them to your project dependencies.
trymodule is a command-line tool that lets developers quickly test and experiment with Node.js npm packages without installing them as project dependencies. It creates an isolated REPL environment where modules are automatically downloaded and loaded for immediate use. This solves the problem of having to modify package.json or install packages globally just to try them out.
Node.js developers who frequently evaluate new npm packages, learners exploring the Node.js ecosystem, and anyone who wants to test library functionality before committing to a dependency.
Developers choose trymodule because it provides the fastest way to experiment with npm packages—no project setup, no dependency management, just instant access to modules in a clean REPL environment. It's specifically designed for quick testing and learning without polluting your development environment.

Downloads and loads npm packages directly into a Node.js REPL, allowing immediate testing without installing them globally or modifying project dependencies, as shown in the usage examples.
Enables loading several modules at once with a single command, facilitating quick comparison and experimentation with multiple libraries, like 'trymodule colors lodash'.
Allows assigning imported packages to custom variable names for easier testing, using syntax such as 'trymodule colors=c lodash=l' to improve REPL usability.
Supports environment variables like TRYMODULE_PATH and TRYMODULE_NONINTERACTIVE for customizing storage paths and interactive behavior, offering flexibility as detailed in the README.
Confined to interactive REPL sessions, making it unsuitable for writing persistent test scripts or integrating packages into full applications, which limits its utility beyond quick exploration.
Lacks the ability to specify npm package versions, potentially leading to compatibility issues when testing against specific releases, as the README doesn't mention version pinning.
Requires an internet connection to download packages, rendering it unusable in offline development environments, with no caching or offline mode described in the documentation.
