tree-sitter-json

To use the tree-sitter configurations in your ESLint setup, import eslint-config-treesitter and spread its exported configuration array into your eslint.config.mjs (Flat Config) file. This allows you to apply tree-sitter-based linting rules to your project.

import treesitter from 'eslint-config-treesitter';

export default [
  ...treesitter,
];

The tree-sitter-json package provides Node.js bindings for the JSON grammar. It can be required directly in a Node.js or Bun environment. The module exports the compiled Tree-sitter grammar object, which is used to parse JSON strings into syntax trees.

If available, the module also exports nodeTypeInfo, which contains metadata about the different node types defined in the JSON grammar (loaded from src/node-types.json).

const Parser = require('tree-sitter');
const JSON = require('tree-sitter-json');

const parser = new Parser();
parser.setLanguage(JSON);

const sourceCode = '{"key": "value"}';
const tree = parser.parse(sourceCode);
console.log(tree.to_string());

The tree-sitter-json module may export a nodeTypeInfo property. This property contains a mapping of node type names to their respective metadata, which is useful for tools that need to understand the structure of the JSON grammar without manually inspecting the tree.

const JSON = require('tree-sitter-json');

if (JSON.nodeTypeInfo) {
  console.log(JSON.nodeTypeInfo);
}
