Understanding npm Developers' Practices, Challenges, and Recommendations for Secure Package Development
This study investigates the security perceptions, practices, and challenges of 75 npm package developers through a mixed-methods survey, revealing that while security is a priority, developers face significant barriers like time constraints and tool limitations, prompting recommendations for improved detection tools, documentation, and education to enhance the ecosystem's trustworthiness.

Imagine the world of software development as a massive, bustling city called Node City. In this city, almost every building (an app or website) is constructed not from scratch, but by snapping together pre-made Lego bricks. These bricks are called npm packages. There are over 2 million of them, and they are downloaded billions of times a month.
The people who build, maintain, and hand out these bricks are the npm developers. They are the architects and caretakers of this city.
This paper is like a town hall meeting where the researchers asked 75 of these brick-makers: "How safe do you think your bricks are? What keeps you up at night? And what tools do you use to keep the city safe?"
Here is what they found, explained simply:
1. The "I Know It's Important, But..." Paradox
The developers all agreed: Security is super important. They care deeply about it. However, when asked to rate the safety of their own bricks, most gave them a "C+" or "B-." They didn't say, "My bricks are perfect." They said, "They're okay, but not great."
- The Analogy: It's like a chef who knows food safety is critical but admits, "My kitchen is clean, but I'm not 100% sure I didn't leave a tiny speck of dust in the soup." They value safety, but they know their own work isn't flawless.
2. The Big Scary Monsters (Threats)
When asked what scares them the most, the developers pointed to three main monsters:
- Supply Chain Attacks: Imagine a thief sneaking into the warehouse where the bricks are stored and swapping a safe red brick for a bomb. This is the #1 fear.
- Dependency Vulnerabilities: Your brick might be safe, but it's glued to another brick that has a crack in it. If that other brick breaks, yours falls too.
- Malicious Code: Someone intentionally putting a trap inside a brick.
3. The Tools: The "Spam Folder" Problem
Developers have tools to check for these monsters (like npm audit or Dependabot). But only 40% of them are happy with these tools.
- The Analogy: Imagine you have a smoke detector in your kitchen. It works great, but it goes off every time you toast a piece of bread or open a window. After a while, you get alert fatigue. You start ignoring the beeping because you think, "Oh, it's just the toaster again."
- The developers said the tools scream "DANGER!" too often about things that aren't actually dangerous (false alarms). This makes them tired and less likely to listen when a real fire starts.
4. How They Fix Things
When a developer finds a crack in their brick, they usually act fast.
- The Process: They check how bad the crack is, fix it, and release a new version immediately.
- The "Drop" Strategy: If a brick they rely on is abandoned (no one is maintaining it) or has a known crack that won't be fixed, they stop using it. It's like realizing a supplier has gone bankrupt, so you switch to a new supplier immediately.
5. The Roadblocks (Why it's hard)
Why don't they make everything perfect? The biggest hurdle is Time.
- The Analogy: Imagine you are building a house while someone is constantly handing you new blueprints, asking you to paint the walls, and telling you to fix the roof. You simply don't have enough hours in the day to double-check every single nail for security.
- Other hurdles include the tools being confusing, the "noise" of too many alerts, and the sheer complexity of managing thousands of connections between bricks.
6. What They Want (The Wish List)
If the city council (npm) could grant them three wishes to make the city safer, here is what the developers asked for:
- Better Detectors: Tools that stop screaming about toast and only scream about real fires. They want smarter tools, not just more tools.
- Clearer Instructions: Better guides and documentation on how to build safely.
- More Support: They want financial help or incentives. Security takes time, and they want to be rewarded for spending that time.
One thing they specifically don't want: They don't want tools that automatically fix the bricks for them without asking. They are wary of robots trying to patch holes because they might patch the wrong thing. They prefer to do the fixing themselves once they know what's wrong.
The Bottom Line
The npm developers are well-meaning and aware of the dangers, but they are overwhelmed. They are trying to keep a massive, interconnected city safe with tools that sometimes cry wolf too often, and they are running out of time. To make the software world safer, we need to give them better, quieter tools, clearer instructions, and a little more time to do the job right.
