Question 1

How to set up Vesper with ncat for a persistent HTTP service?

Accepted Answer

Use ncat with the -lk flag and --sh-exec to execute your Bash script on each request, as shown in the examples. For instance, 'ncat -lk -p 8081 --sh-exec examples/router.sh' starts a server that handles incoming HTTP traffic.

Question 2

Is Vesper suitable for building REST APIs?

Accepted Answer

Only for simple GET-based APIs due to its limited method support. For full REST capabilities with POST, PUT, or DELETE, you'd need to extend it yourself or choose a more comprehensive framework.

Question 3

Vesper vs Python Flask for a quick prototype API?

Accepted Answer

Vesper is faster to integrate if you're already in a Bash environment and need minimal HTTP handling, but Flask offers more features, better documentation, and broader community support for complex prototypes.

Question 4

What are the security risks of using Vesper?

Accepted Answer

Since it relies on shell scripts and ncat, risks include shell injection vulnerabilities if inputs aren't sanitized, and lack of built-in security features like HTTPS or authentication, requiring manual implementation.

Question 5

Can Vesper handle file uploads?

Accepted Answer

Not directly supported in the current version; the examples focus on serving files and generating content, so you'd need to parse multipart/form-data manually, which is complex and error-prone in Bash.

Question 6

How does Vesper compare to other shell HTTP tools like bashttpd?

Accepted Answer

Vesper is more of a framework for integrating HTTP into scripts, while bashttpd is a full web server in Bash. Vesper is lighter and more composable, but bashttpd might offer more built-in features out of the box.
