How to add JSON-LD in React

1. 01

   Build a plain data object

   Keep structured data separate from HTML strings.

2. 02

   Serialize safely

   Use JSON.stringify on trusted application data and escape output as required by the framework.

3. 03

   Render on the correct route

   The object should describe the visible page and canonical URL.

4. 04

   Avoid duplicate hydration output

   Confirm server and client rendering do not publish conflicting scripts.

5. 05

   Test rendered production HTML

   Validate the deployed route, not only the component source.

Validate the final production output in layers: JSON syntax, Schema.org vocabulary, current feature-specific requirements, visible content, and crawl access.

• Define the purpose and expected result of json-ld in react.
• Capture the current state using visible entities, page purpose, JSON-LD graphs, identifiers, relationships, required properties, and consumer-specific eligibility.
• Identify the source template, component, plugin, content owner, and release path that controls the output.
• Prepare a test case, approval path, backup or rollback method, and post-release verification plan.

• Parse the deployed json-ld, validate the graph, compare it with visible content, and test any target consumer requirements.
• Check representative page types and edge cases instead of confirming only the example used during implementation.
• Confirm the change did not create publishing properties that are unsupported, hidden, stale, or inconsistent with visible content.
• Record the implementation date, owner, release reference, evidence, and next review trigger.
