Regex is a module that builds on the existing RegExp
module, making it easier working with text matching and replacment in JavaScript both in the browser
and in Node.JS
environment.
Single Browser distributable bundle is located inside dist folder.
npm install @teclone/regex
import { replace } from '@teclone/regex';
let text = 'Is is Is is Is';
console.log(replace('is', 'are', text)); // are are are are are
// respect case (case sensitive)
console.log(replace('is', 'are', text, true)); // Is are Is are Is
// replace only first occurence, case sensitive false
console.log(replace('is', 'are', text, false, 1)); // are is Is is Is
// replace only first 2 occurences, case sensitive false
console.log(replace('is', 'are', text, false, 2)); // are are Is is Is
import { replaceCallback } from '@teclone/regex';
const text = 'He loves her';
console.log(
replaceCallback(
['he', 'she'],
function(matches, count) {
if (matches[0].toLowerCase() === 'he') return 'She';
else {
return 'him';
}
},
text,
),
); // logs She loves him
to reference a captured parameter in replacement text, use the format $:number
. e.g $:1, $:2, $:3
import {replace} from '@teclone/regex';
const text = '2222 is the amount';
console.log(
replace(/(\d+)/, '$$:1', text)).toEqual('$2222 is the amount')
);
