Extract tagged template literals

Search and extract tagged template literals from javascript/typescript file.

Installation

yarn add extract-tagged-template-literals

Usage

It's possible to use more than one tag via the | (regex or separator), valid tags:

• hbs
• hbs|handlebars
• hbs|handlebars|dotted.string

searchAndExtract(documentContent: string, tag: string): string;
// or the hbs wrapper
searchAndExtractHbs(documentContent: string): string;

Example

import { searchAndExtract } from 'extract-tagged-template-literals';

const tag = 'hbs';
const documentContent = `
  import GlimmerComponent from '@glimmer/component';
  // @ts-ignore
  import hbs from 'ember-cli-htmlbars-inline-precompile';

  const template = hbs\`
    <div class="input {{this.type}}">
      <label>{{yield}}</label>
      <input type={{this.type}} value={{this.value}}>
    </div>
  \`;

  interface IComponentArgs {
    type: string;
    value?: any;
  }

  class MyInputComponent extends GlimmerComponent<IComponentArgs> {
    type: string = 'text';
  };

  // @ts-ignore
  export default Ember._setComponentTemplate(template, MyInputComponent);
`;

const extractedTaggedTemplateLiterals = searchAndExtract(documentContent, tag);
console.log(extractedTaggedTemplateLiterals);

Output:

                                                    
               
                                                         

                       
    <div class="input {{this.type}}">
      <label>{{yield}}</label>
      <input type={{this.type}} value={{this.value}}>
    </div
