Looking to utilize the validator in my express project. Is there a way to import only specific packages directly?
For example:
import {isEmail, isEmpty} from 'validator';
Alternatively, importing each on a separate line.
Curious if there is another option besides import validator from 'validator'; as mentioned on the https://www.npmjs.com/package/validator
const isEmailValidator = require('validator').isEmail;
const isEmptyValidator = require('validator').isEmpty;
isEmailValidator('<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c7a5aba687a5aba6e9a4a8aa">[email protected]</a>');
Is this the format you were thinking of? Your original approach is also valid:
import {isEmail, isEmpty} from 'validator';
isEmail('<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7c1e101d3c1e101d521f1311">[email protected]</a>');
Additional clarification: The validator.js library exports an object with each function as shown here https://github.com/chriso/validator.js/blob/master/src/index.js. You can import all functions using
import validator from 'validator'const {isEmail, isEmpty} = require('validator');
Node will continue to import the entire validator module despite this. The code simply instructs Node to load the object returned by the module's export and then extract the isEmail and isEmpty values from it.
Once ES6 modules are fully supported, you may be able to use the standard import syntax. For more information, refer to the node.js documentation on ECMAScript Modules.
