bugstack for Go

Auto-fix nil pointer dereference, index out of range, and concurrency panics in Gin, Echo, and Go stdlib.

What Go Errors bugstack Fixes

• nil pointer dereference — accessing fields or methods on nil pointers
• index out of range — accessing slices or arrays beyond their bounds
• concurrent map read/write — race conditions on unsynchronized maps
• send on closed channel — writing to a channel that has already been closed

Install the SDK

Add bugstack to your Go module:

go get github.com/MasonBachmann7/Bugstack-Go

Then initialize it in your main function:

import "github.com/MasonBachmann7/Bugstack-Go/bugstack"

func main() {
    bugstack.Init(bugstack.Config{
        APIKey: os.Getenv("BUGSTACK_API_KEY"),
    })
    defer bugstack.Flush()

    // your application code
}

Example Fix

bugstack detects a nil pointer dereference panic and writes a surgical fix:

func GetUserEmail(id int) string {
    user := findUserByID(id)
    return user.Email
}

// Runtime panic when user is nil:
// panic: runtime error: invalid
//   memory address or nil pointer
//   dereference

func GetUserEmail(id int) (string, error) {
    user := findUserByID(id)
    if user == nil {
        return "", fmt.Errorf(
            "user %d not found", id,
        )
    }
    return user.Email, nil
}
