The Problem with Current Dev Mode

Oct 13, 2025 by wbrum.org 37 views

Introduction

As developers, we often find ourselves in a situation where we need to test and iterate on our code quickly. This is especially true when working with Node.js and its vast ecosystem of packages. In this article, we will explore the concept of a "dev mode" for testing Node packs, and how it can enhance the development experience.

The Problem with Current Dev Mode

The current dev mode toggle in Node.js doesn't seem to do much, especially with the introduction of the export workflow_api.json option by default. This has led to a situation where developers are left wondering what the dev mode toggle is actually for.

What is Dev Mode?

Dev mode, in the context of Node.js, is a feature that allows developers to test and iterate on their code quickly. It's a mode that enables developers to make changes to their code, save it, and see the changes reflected in their application without having to restart the server or run the application again.

The Ideal Dev Mode for Node Packs

The ideal dev mode for Node packs would be a feature that allows developers to toggle an --editable mode for Node packs or classes that are actively being developed. This would enable developers to re-init the Node pack or class at runtime, cutting down on the wait time in the feedback loop while making new nodes.

How Does it Work?

The --editable mode would work similarly to the pip install -e command in Python. When a developer enables the --editable mode for a Node pack or class, they would be able to make changes to the code, save it, and see the changes reflected in their application without having to restart the server or run the application again.

Benefits of Dev Mode for Node Packs

The benefits of dev mode for Node packs are numerous. Some of the benefits include:

Faster Development Cycle: With dev mode, developers can test and iterate on their code quickly, reducing the time it takes to develop and deploy new features.
Improved Productivity: Dev mode enables developers to make changes to their code, save it, and see the changes reflected in their application without having to restart the server or run the application again.
Enhanced Collaboration: Dev mode allows multiple developers to work on the same codebase simultaneously, making it easier to collaborate and share code.

Existing Solutions

While there are no existing solutions that provide a dev mode for Node packs, there are some alternatives that can help achieve similar results. Some of the alternatives include:

Using a Build Tool: Build tools like Webpack, Rollup, and Babel can help developers compile and bundle their code, making it easier to test and iterate on their code.
Using a Code Editor: Code editors like Visual Studio Code, Sublime Text, and Atom provide features like live reloading, code completion, and debugging, making it easier to test and iterate on code.

Conclusion

In conclusion, a dev mode for testing Node packs would be a game-changer for developers. It would enable developers to test and iterate on their code quickly, reducing the time it takes to develop and deploy new features. While there are no existing solutions that provide a dev mode for Node packs, there are some alternatives that can help achieve similar results.

Future Work

In the future, we would like to see a dev mode feature that allows developers to toggle an --editable mode for Node packs or classes that are actively being developed. This would enable developers to re-init the Node pack or class at runtime, cutting down on the wait time in the feedback loop while making new nodes.

Recommendations

Based on our research and analysis, we recommend the following:

Develop a Dev Mode Feature: Develop a dev mode feature that allows developers to toggle an --editable mode for Node packs or classes that are actively being developed.
Improve the Current Dev Mode Toggle: Improve the current dev mode toggle to provide more functionality and features.
Provide Alternatives: Provide alternatives to dev mode, such as using a build tool or a code editor, to help developers achieve similar results.
