How to implement Joi validation in hapi.js? - node.js

Question

I just want to implement Joi in Hapi API.
server.route([
{
method: 'POST',
path: '/login',
config: {
tags: ['login', 'auth'],
auth: false,
validate: {
payload: payloadValidator,
failAction: (req, h, source, error) => {
console.log("Error ::: ", source.details[0].message);
return h.response({ code: 0, message: source.details[0].message });
}
}
},
handler: async (request, h) => {
console.log(request.payload.email);
console.log(request.payload.password);
...
}
}
]);
Hear I call payloadValidator.
const payloadValidator = Joi.object({
email: Joi.string().required(),
password: Joi.string().required()
}).options({ allowUnknown: true });
Actually I'm new with hapi and I'm missing something in my code. Can anyone help me to fix this issue?
Required output
If I do not pass email then the app must throw an error of Email is required and it should be the same with the password field also.
Error:
Error ::: "email" is required

Error: Lifecycle methods called before the handler can only return an error, a takeover response, or a continue signal

Answer 1

As an error suggests Lifecycle methods called before the handler can only return an error, a takeover response, or a continue signal you have to return takeover response.
return h.response({ code: 0, message: source.details[0].message }).takeover();
