JSON:API is a specification for building APIs in JSON that defines conventions for resource objects, relationships, links, pagination, filtering, and sorting. It reduces bikeshedding in API design and has client libraries for JavaScript, Ruby, Python, PHP, and other languages.

HTML

<!-- Set MIME type in meta or fetch headers -->
<meta http-equiv="Content-Type" content="application/vnd.api+json">

Node.js

// Express.js
app.get('/file', (req, res) => {
  res.type('application/vnd.api+json');
