express-validation-map

Under the inspiration of these libraries express-validation and minimalistic-js, I have written my own library which validate data (more convenient for me) as middleware, for the framework "express.js".

Getting Started

$3

``
npm install express-validation-map -S
`

Setup

Add a middleware to the any router and throw a validationMap object into it.

Example a part server.js file:

`
app.route('/user/:id')
.put(
onValidation(updateUserValidationMap),
(req, res) => {
// Some logic
// ...
}
);
....

`
Example a part server.js file:

`
const updateUserValidationMap = {
config: {
code: 502,
message: "custom"
},
params: {
id: {
methods: {
required2: methods.isRequired,
isInteger: methods.isInteger
},
messages: {
required2: isRequiredText,
isInteger: isOnlyIntegerText
}
},
},
body: {
firstName: {
methods: {
required: methods.isRequired,
isName: methods.isName
},
messages: {
required: isRequiredText,
isName: isNameText
}
},
lastName: {
methods: {
required: methods.isRequired,
isName: methods.isName,
is23: is23,
},
messages: {
required: 'asdasdasdasd',
isName: isNameText,
is23: 'it is number 23'
}
},
email: {
methods: {
required: methods.isRequired,
isEmail: methods.isEmail,
},
messages: {
required: isRequiredText,
isEmail: isEmail
}
},
},
};

`

Where params, body and query is input data and config need only for define own properties:
code - http status,
message - 'erros.validations

``
const validationMap = {
[query|params|body]: {
[field]: {
methods: {
key1: anyMethod1,
key2: anyMethod2,
key3: anyMethod3
},
messages: {
key1: messageForMethod1,
key2: messageForMethod2,
key3: messageForMethod3,
}
}
}
};
``

That is all!

Enjoy :)
