Have you ever used Mongoose's schema validation and thought, "Hey this is way better than every schema validation library, why can't I just use it for validation?" Well, technically you could do it with just Mongoose, but you would end up with collections for every model you made and it would be a big mess.
Enter MAAV. It uses the existing Mongoose schemas and validation logic without involving the database layers that otherwise come with Mongoose.
Because this module uses mongoose, it has a peer-dependency of mongoose@5.x or higher. If you do not install mongoose, this won't work.
Warning: This project is still in a WIP state, which means its API is not yet stable. It may change drastically in the future.
npm i maav
const { Validator, Schema } = require('maav');
const ValidNameSchema = new Schema({
name: {
type: String,
required: true,
validate: /[^\d]/
}
});
const SubmitNameRequest = new Validator.compile(ValidNameSchema);
router.post('/submitName', async (req, res) => {
let nameSubmission = new SubmitNameRequest(req.body);
try {
await nameSubmission.validate();
} catch (e) {
return res.status(400).send({
error: e.firstError()
});
}
// Now we can be sure nameSubmission is valid
// If you need a pure JS verison of the valid object
// we can call nameSubmission.toObject()
});Just reference Mongoose's own validation documentation
- Is this officially supported by mongoose?
- LOL no, please don't bug @Automattic for anything you encounter in this library unless you can reproduce within a purely mongoose environment. He does really good work, seriously. This module would not be possible if mongoose didn't exist. Don't be a jerk.
- Can I do X with this like I can in mongoose?
- Just try it, see if it works. If not, and you really want to, you could always open an issue to ask about it. If it's a good idea maybe I'll work on it. Also, I will accept pull requests which are not stupid ideas either.
