Editorjs2html

editorjs2html is a utility that converts Editor.js output into HTML.

Features

• Supports multiple Editor.js block types
• Converts structured JSON data into clean HTML with semantic CSS classes
• Easy to use and integrate into projects
• Includes custom CSS classes for styling flexibility

Supported Block Types

This library supports conversion for the following Editor.js block types with corresponding CSS classes:

Note:

• Inline Text blocks (js-inline) support the following styles based on flags (in order):
  • bold → <b>
  • italic → <i>
  • underline → <u>
  • marker → <mark>
  • inline_code → <code>
    The styles are applied in sequence and the final HTML is wrapped in a div like:

  <div class="js-inline"><code><mark><u><i><b>Text</b></i></u></mark></code></div>
  

• Checklist blocks (js-checklist) contain individual checkbox items each wrapped in a div with the js-checkbox class. (this only for older version of checklist)
• Alert blocks (js-alert) have subclasses for different alert types:
  • js-alert-primary
  • js-alert-secondary
  • js-alert-info
  • js-alert-success
  • js-alert-warning
  • js-alert-danger
  • js-alert-light
  • js-alert-dark
• Image blocks (js-image) support the following modifier classes:
  • js-image--stretched (if stretched is true)
  • js-image--bordered (if withBorder is true)
  • js-image--background (if withBackground is true)
• We support both delimiter block plugins:
  • delimiter
  • editorjs-delimiter

                }
            },
            {
                "id" : "af5jCp7vmJ",
                "type" : "paragraph",

                }
            },
            {
                "id" : "image1",
                "type" : "image",
                "data" : {
                    "file" : {
                        "url" : "https://www.tesla.com/tesla_theme/assets/img/_vehicle_redesign/roadster_and_semi/roadster/hero.jpg"
                    },
                    "caption" : "Roadster // tesla.com",
                    "withBorder" : false,
                    "withBackground" : true,
                    "stretched" : true
                }

                    "inline_code": true
                }
            }
        ]
    });
    let html_content = editorjs2html::to_html(&content.to_string()).unwrap();
    println!("converted to html: {}", html_content)
}

Example Output for Image Block

For the above JSON input, the generated HTML for the Image block will look like this:

<div class="js-image js-image--stretched js-image--background">
    <img src="https://www.tesla.com/tesla_theme/assets/img/_vehicle_redesign/roadster_and_semi/roadster/hero.jpg" alt="Roadster // tesla.com">
    <p>Roadster // tesla.com</p>
</div>

Example Output for Inline Text Block

<div class="js-inline"><code><mark><u><i><b>Hello</b></i></u></mark></code></div>

Styling

The generated HTML includes semantic CSS classes for each block type, allowing you to apply custom styles. Use the corresponding class names from the Supported Block Types table to target specific elements in your CSS.

Example styling for headers:

.js-head h2 {
  color: #2c3e50;
  font-family: system-ui;
}

Styling checklist items:

.js-checkbox {
  display: flex;
  gap: 8px;
  align-items: center;
}

Styling image blocks:

.js-image {
  margin: 1rem 0;
}

.js-image--stretched {
  width: 100%;
}

.js-image--bordered {
  border: 2px solid #ccc;
}

.js-image--background {
  background-color: #f5f5f5;
  padding: 1rem;
}
