Simple input validation
Why?
Almost any project needs a form validation. This package simplifies your workflow.
Installation
npm i -S input-isor
yarn add input-isUsage
After installation you can import the package to your project and use a declarative way to validate your form inputs.
The return value is always a boolean, e.g. true or false.
Here is a litte example:
import inputIs from 'input-is'; // const inputIs = require('input-is');
inputIs.email('hello'); // false
inputIs.email('example@mail.com'); // trueFunctions:
- date
- datetime
- exactly
- filled
- float
- integer
- max
- min
- not
- number
- partOf
- phonenumber
- time
- url
- valid
date
Note: you have to pass the format of the
dateas second parameter to the function
This function validates if a form input is a valid date
return value: boolean
// valid formats:
// YYYY-MM-DD, MM-DD-YYYY,
// DD-MM-YYYY, YYYY/MM/DD,
// MM/DD/YYYY, DD/MM/YYYY,
inputIs.date('100/100/1000'); // false
inputIs.date('12/12/2017', 'DD/MM/YYYY'); // truedatetime
Note: you have to pass the format of the
dateas second parameter to the function
This function validates if a form input is a valid datetime
return value: boolean
// valid formats:
// YYYY-MM-DD hh:mm:ss, YYYY-MM-DD hh:mm,
// MM-DD-YYYY hh:mm:ss, MM-DD-YYYY hh:mm,
// DD-MM-YYYY hh:mm:ss, DD-MM-YYYY hh:mm,
// YYYY/MM/DD hh:mm:ss, YYYY/MM/DD hh:mm,
// MM/DD/YYYY hh:mm:ss, MM/DD/YYYY hh:mm,
// DD/MM/YYYY hh:mm:ss, DD/MM/YYYY hh:mm,
inputIs.datetime('12/12/2017'); // false
inputIs.datetime('12/12/2017 12:12:12', 'DD/MM/YYYY'); // trueThis function validates if a form input is a valid email
return value: boolean
inputIs.email('example.mail.com'); // false
inputIs.email('example@mail.com'); // trueexactly
This function validates if a form input is a exactly the same as a target
return value: boolean
inputIs.exactly('this should be', 'exactly like this target'); // false
inputIs.exactly('exactly the same', 'exactly the same'); // truefilled
This function validates if a form input is filled, e.g. the value is minimum one character long
return value: boolean
inputIs.filled(''); // false
inputIs.filled('1'); // truefloat
This function validates if a form input is a valid float (not type number)
return value: boolean
inputIs.float('1'); // false
inputIs.float('1.0'); // trueinteger
This function validates if a form input is a valid integer (not type number)
return value: boolean
inputIs.integer('z'); // false
inputIs.integer('990'); // truemax
This function validates if a form input is maximum the length of target
return value: boolean
inputIs.max('value', 3); // false
inputIs.max('value', 5); // truemin
This function validates if a form input is minimum the length of a target
return value: boolean
inputIs.min('value', 6); // false
inputIs.('value', 3); // truenot
This function validates if a form input is not like the target
return value: boolean
inputIs.not('target', 'target'); // false
inputIs.not('value', 'target'); // truenumber
This function validates if a form input is a valid number (not type number)
return value: boolean
inputIs.number('number'); // false
inputIs.number('1'); // truepartOf
This function validates if a form input is part of a provided characterset
return value: boolean
inputIs.partOf('z', 'part of ABC'); // false
inputIs.partOf('ABC', 'part of ABC'); // truephonenumber
This function validates if a form input is a valid phonenumber
return value: boolean
inputIs.phonenumber('+12'); // false
inputIs.phonenumber('+1234567890'); // truetime
This function validates if a form input is a valid time
return value: boolean
inputIs.time('01:'); // false
inputIs.time('01:01'); // trueurl
This function validates if a form input is a valid url
return value: boolean
inputIs.url('google.'); // false
inputIs.url('https://www.google.com'); // truevalid
This function validates form input to a regular expression
return value: boolean
inputIs.valid('google', /.at/); // false
inputIs.valid('hat', /.at/); // trueLICENSE
