Ecto_command - a toolkit for mapping, validating, and executing commands
Hello guys,
I often find myself working on projects where I accept commands from external sources (usually via HTTP APIs, but they could also come through the shell or other means).
The input data needs to be validated before it can be used, and after trying out various validation libraries, I have come to the conclusion that it is probably best to leverage Ecto’s validation feature for this task.
However, I find Ecto a bit cumbersome and verbose when it comes to specifying fields and how they should be validated. For these and other reasons, I have created this library: GitHub - silvadanilo/ecto_command.
This library allows you to specify which fields are available for a particular command, how they should be validated, and if the input data is valid, it allows the execution of that specific command.
I would appreciate any feedback and suggestions on how to improve the library. Please take a look at the GitHub repository and share your thoughts.
Thank you in advance for your support and contributions!

I’ve seen it somehow few weeks ago and I think it’s pretty cool implementation, if someone uses commands. I agree with you that Ecto input validation is great, but it’s tied a bit too much to persistence layer (at least conceptually) and is much harder to use outside of persistence contexts. This, in turn, lead to database-driven development. It’s freat to have an abstraction to overcome this.
