Installation

yarn add ember-extract-inline-templates

Usage

API:

searchAndExtractHbs(source: string, options?: ISearchAndExtractHbsOptions): string | never;

getTemplateNodes(source: string, options?: IGetTemplateNodesOptions): ITemplateNode[];

Options:

• hbsTagSources - [Optional] The additional hbs tag sources used in the import declaration(s), e.g.:

  {
    "hbs-source-with-default-export": "default", // import hbs from 'hbs-source-with-default-export';
    "hbs-source-with-named-export" : "handlebars", // import { handlebars } from 'hbs-source-wth-named-export';
    "hbs-source-with-renamed-export": "hbs" // import { hbs as h } from 'hbs-source-with-renamed-export';
  }

  Default hbs tag sources:

  {
    "ember-cli-htmlbars": "hbs",
    "htmlbars-inline-precompile": "default",
    "ember-cli-htmlbars-inline-precompile": "default",
    "@glimmerx/component": "hbs",
  }

• babylonPlugins - [Optional] The additional babylon plugins to use, e.g. [ 'typescipt', 'jsx' ], see: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/babylon/index.d.ts#L45.

  Default used babylon plugins: [ 'flow', 'classProperties' ]

• sortByStartKey - [Optional] The extracted template nodes from the ast will not be ordered by their original position in the source, so we can sort them using the start key, false by default.

Example

import { searchAndExtractHbs } from 'ember-extract-inline-templates';

const source = `
  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 hbs = searchAndExtractHbs(source);
console.log(hbs);

Output:

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