How To Use Joi for Node API Schema Validation
Create validation schema for the request data parameters.
Handle validation errors and give appropriate feedback.
Create a middleware to intercept and validate requests.
Joi can be used for creating schemas (just like we use mongoose for creating NoSQL schemas) and you can use it with plain Javascript objects. It's like a plug n play library and is easy to use. On the other hand, express-validator uses validator. js to validate expressjs routes, and it's mainly built for express.
Roadmap
Create login , register , post joi schemas.
Export all schemas as single
module( validators/index.js )
Create configurable middleware that takes
schema name as parameter and validates
request body( middlewares/Validator.js )
Create auth and post routes.
Create expressjs instance.
