Create a secure temporary file in Go using os.CreateTemp and defer os.Remove for automatic cleanup.
Use os.CreateTemp to create a secure temporary file and defer os.Remove to ensure it is deleted after use.
f, err := os.CreateTemp("", "pattern-*")
if err != nil {
return err
}
defer os.Remove(f.Name())
// Write to f
_, err = f.WriteString("data")
if err != nil {
return err
}
err = f.Close()
Working with temporary files in Go creates a unique file in your system's temporary folder that no one else can guess the name of. You write your data to it, and the code automatically deletes the file when you are done. It is like using a scratchpad that erases itself the moment you close it.
