AppMap for Visual Studio Code

AppMap is a free and open-source runtime code analysis tool.

AppMap records code execution traces, collecting information about how your code works and what it does. Then it presents this information as interactive diagrams that you can search and navigate. In the diagrams, you can see exactly how functions, web services, data stores, security, I/O, and dependent services all work together when application code runs.

Requirements

Supported web applications and API frameworks: Ruby on Rails, Django, Flask, Express, and Spring.

Supported programming languages: Java, Python, Ruby, TypeScript/JavaScript (for Node.js applications only).

To start making AppMaps, you’ll need to install and configure the AppMap client agent for your project. Then, you’ll make AppMaps by running your app - either by running test cases, or by recording a short interaction with your app.

AppMap Features

Runtime behavior visualization

AppMap for Visual Studio Code includes a variety of interactive diagrams to help you understand your application's runtime behavior.

Sequence Diagrams to follow the runtime flow of calls made by your application:

Dependency Maps to see which libraries and frameworks were used at runtime:

Flame Graphs to spot performance issues and bottlenecks:

Trace Views to perform detailed function call and data flow tracing:

Runtime analysis

After making recordings of how your application behaved at runtime, AppMap analyzes those recordings to automatically detect performance issues like N+1 queries, and security flaws such as faulty authentication logic.

AppMap in CI

The same features available in this plugin are also available for CI systems. AppMap analyzes your applications after your CI tests run, and produces a report in GitHub containing behavior changes, failed test analysis, runtime API differences, performance issues, and dynamic security flaws:
