Handlebars Serializer

Serialize Handlebars AST into template string.

Useful when you want to parse a Handlebars template into an Abstract Syntax Tree (AST), add/remove/modify nodes, then it serialize back to Handlebars template.

Also includes a Transformer that could be used as a base class for performing such transformations. The following example uses marked to compile all text content into Markdown:

// markdown-transformer.js
import Transformer from 'handlebars-serializer/transformer';

export default class MarkdownTransformer extends Transformer {
  content(content) {
    var string = content.string;

    // Don't parse whitespace
    if (!string.match(/[^\s]/g)) {
      return content;
    }

    content.string = marked(string);

    return content;
  }
}

// app.js
import Handlebars from 'handlebars';
import MarkdownTransformer from './markdown-transformer';

var template = '{{#if shouldSayHello}} Hello **World** {{/if}}';
var ast = Handlebars.parse(template);
var mdTemplate = new MarkdownTransformer().accept(ast);

console.log(mdTemplate); // {{#if shouldSayHello}} Hello <strong>World</strong> {{/if}}
