How to Use the Handlebars Formatter
Handlebars templates mix HTML structure with block helpers like {{#each}} and {{#if}}. When templates are auto-generated or manually edited without proper indentation, nested blocks become hard to track. A Handlebars formatter fixes block nesting and restores consistent HTML indentation throughout your templates.
Step 1: Paste Your Template
Copy your Handlebars .hbs or .handlebars file contents into the input area. The formatter accepts both inline expressions and full page templates with block helpers.
Step 2: Choose Indentation
Select 2 spaces, 4 spaces, or tabs to match your project's code style. Click Format Handlebars to apply. The formatter will indent HTML tags and increase nesting depth inside every {{#block}} helper.
Step 3: Review Block Indentation
Block helpers like {{#each items}} increase the indentation level; closing helpers like {{/each}} decrease it. Partial includes {{> partialName}} are placed on their own line with the current indentation depth. Inline helpers and variables stay on the same line as their surrounding HTML.
Handlebars Template Best Practices
Keep block helpers clearly nested — each {{#if}} should visually match its {{/if}}. Avoid deeply nested templates by extracting sub-templates into partials. Comments {{!-- this is a comment --}} are stripped from compiled output but remain useful during development.
FAQ
Is the Handlebars formatter free?
Yes, completely free with no signup required. Format unlimited Handlebars templates in your browser.
Is my template code safe?
Yes. All formatting runs locally in your browser. Your Handlebars templates are never sent to any server.
Which Handlebars helpers are supported for indentation?
Block helpers that increase indentation: {{#each}}, {{#if}}, {{#unless}}, {{#with}}, {{#let}}, {{#block}}, and any custom block helpers. Closing tags {{/each}}, {{/if}}, etc. decrease indentation. Inline helpers like {{helper arg}} stay on the same line.
Does the formatter handle partials and comments?
Yes. Partial calls {{> partial}} are placed on their own line with proper indentation. Handlebars comments {{!-- comment --}} are preserved in place.
Can I format Ember.js templates with this tool?
Yes. Ember.js uses Handlebars syntax, so components, helpers, and block expressions will all format correctly with this tool.
Can I minify Handlebars templates?
Yes. The Minify button collapses whitespace in your template while preserving Handlebars expressions, useful for reducing file size in production.
