Needler

---

Get tired of having to fool with regex to find a value in between two tags?

Example: <title>Get this value</title>

---

This is a lightweight tool that will do just this for you, as well as replace those values if need be.

To install:

npm install needler

Example of usage for finding a value in between something:

  var needler = require('needler');

  var options = {
    haystack: 'The word inside of <bold>tag</bold> will be returned.',
    header: '<bold>',
    footer: '</bold>'
  }

  var result = needler.find(options, function (error, match) {
    if (error) {
      console.log(error);
    }

	// Will return 'tag'
    console.log(match);
  });

Example of usage for replacing a value in between something:

  var needler = require('needler');

  var options = {
    haystack: 'The word after <this>WOOHOO</this>.',
    replace: 'it was changed!',
    header: '<this>',
    footer: '</this>',
    flags: 'i' //g, i, m, etc. Can be combined.
  }

  var result = needler.replace(options, function (error, result) {
    if (error) {
      console.log(error);
    }

	// Will return 'The word after <this>it was changed!</this>.'
    console.log(result);
  });

ES6

Needler is also compatible with es6 importing. You can do so like below:

import { find, replace } from 'needler';

  import { find, replace } from 'needler';

  let options = {
    haystack: 'The word after <this>WOOHOO</this>.',
    replace: 'it was changed!',
    header: '<this>',
    footer: '</this>',
    flags: 'i' //g, i, m, etc. Can be combined.
  }

  replace(options, (error, result) => {
    if (error) {
      console.log(error);
    }

	// Will return 'The word after <this>it was changed!</this>.'
    console.log(result);
  });

options

haystack (find, replace) [string | required] - String that you will be searching.

replace (replace) [string | required] - String that you will be replaces the value with.

header (find, replace) [string | required] - String before the value you are searching for. For instance - <title>value</title>: In this example, the header would be <title>

footer (find, replace) [string | required] - String after the value you are searching for. For instance - <title>value</title>: In this example, the header would be </title>

flags (replace) [string | required] - String that holds the flags for RegExp. (i, g, m). These can be combined like so: gim. For more information on flags, Visit this Website

Todo

1. At the moment, replace ignores leading and trailing spaces. Wanting to add options for that.
