El Validator is a JSON Object validator and sanitizer. It's a great little tool for validating user input and sanitizing. Define a schema and validate it against the user input. It's inspired from the familiar Mongoose schema format with a few more features.

Hey Hunters 👋! This year I'll be building 10 products/businesses in public and this is project #5! While building the backend of project #4 (a travel social network) that is not launched yet, I've came to the step where I needed to validate and sanitize user input. I basically get a JSON object with various fields, some of them are strings, numbers, sub-fields... And validating that stuff is tedious and boring! It's often the step that is the most bug-prone (i.e. you check that the length of a field is > 5 but didn't check that the field is a string to start with). And it's the part where you need to be the most careful since user-input is the starting point of all security flaws. That's where El Validator comes in! You specify a schema (similar to Mongoose schemas) and then validate the user input. It's very flexible and saves a lot of time! - It's 100% Open-Source - 0 dependencies - Easy to use - Lightweight (8.7Kb minified) I'm open to feedback to improve the tool. If you want to follow my build-in-public challenge, follow me on twitter @ybouane, I post daily updates.
