The AppMap process for smooth, efficient code reviews

AppMap provides tools and strategies to prepare your code for review, and to guide the reviewer through your code changes so that they are easy to approve. Explore your code more efficiently with interactive, accurate software architecture diagrams right in your IDE. Here’s a high-level overview of the AppMap process.

Design for maintainability

Senior devs worry about maintainability more than any other code quality factor. They know that if a project becomes hard to maintain, its quality will suffer in all other areas too. AppMap creates interactive diagrams of your code, which you can use to assess and optimize your code design. Clean design makes code changes easy to review and approve.

Optimize performance

Premature optimization is the root of all evil, they say. What they don’t say is that slow algorithms and slow queries can ruin the user experience of your app. AppMap helps you identify and assess critical algorithms in the code, and it tracks all SQL queries and ties them directly back to the code.

Audit security

Security problems, especially errors in authentication and authorization, are more common than you’d think. And it’s not enough to avoid insecure dependencies. AppMap helps you and the reviewer identify, inspect, and verify the security-sensitive areas of your code.

Improve reliability

When code goes into production and breaks the app, it has to be reverted and fixed. This is painful and expensive. It takes a little extra time to add automated tests, but it’s well worth the effort. AppMap makes tests even more useful, turning each one into beautiful, interactive diagrams of your code architecture and behavior.

"A very useful extension that really helped me better understand and analyze the hierarchy and structure of my applications. Looks awesome, performs great, and provides truly invaluable feedback! This was super helpful in allowing me to better structure and debug my own app and I cannot wait to see what the future holds for AppMap!"
