How to use joi validator with strapi.js? - joi

Question

I have worked a lot with joi with node's express and little with Hapi.js. And now I'm exploring the Strapi.js. Now I have marked that when I create a Content Type builder it gives me basic CRUD API's. Now I want to validate all request using joi. As strapi makes all routes in JSON file. So how could I use joi? I had search a lot but I'm not getting any solution on this.
I have found one solution like this.
{
"method": "POST",
"path": "/users",
"handler": "users.create",
"validate":{ <---------------- Hear I can validate my req
body:{
fname: Joi.string().required()
}
},
"config": {
"policies": []
}
}
Hear the issue is they used Joi but I have to define its package name but hear I have a JSON file so I'm not able to do like this.
Is there anyone has a solution to this?
Update
I have renamed the file as a router.json.
const router = require('koa-joi-router');
const Joi = router.Joi;
module.exports = {
"routes": [
{
"method": "POST",
"path": "/tests",
"validate":{
"body":{
"name":Joi.string().required()
}
},
"handler": "Test.create",
"config": {
"policies": []
}
},
]
}
Still Joi is not working.

OKay after having investigated on this topic, you will not be able to manage your validation in this way.
I suggest you to manage your validation layer with a middleware.
Use your route file with a JSON format (like the default one)
then in the config object you add the validation key that contains your validation schema. But you validation skema will be a string.
Here is an example:
{
"method": "POST",
"path": "/articles",
"handler": "Article.create",
"config": {
"policies": [],
"validate":{
"body":{
"name": "string.required"
}
}
}
},
Then you will have to follow the Middleware documentation 📚 to create you validation middelware.
In this middleware you will be able to get the requested url with ctx.request.url and with a .find() in strapi.config.routes you will be able to find your validation configs.
Then you will have to use the JSON validation config you set and recompose the Joi validation on your request body - ctx.request.body

For the routes.json file, you can rename it routes.js and add a module.exports and your json file become an js file.
{
"routes": [
{
"method": "GET",
...
-
module.exports = {
"routes": [
{
"method": "GET",
But it's only a part of the response.
