Struggling to get plugin to work with typescript parser...

[joeprivettsmart]

Hello, do you have an example of how to set-up the configuration when using this plugin with the typescript parser?

In my config I use:

import jsoncPlugin from 'eslint-plugin-jsonc';
import jsoncParser from 'jsonc-eslint-parser';

import { getJsonFiles } from '../utilities/eslint-files.js';

/**
 * Get ESLint config for imports check
 * @returns {Promise<import('eslint').Linter.FlatConfig[]>}
 */
export async function createEslintJsonConfig() {
    return [
        {
            files: await getJsonFiles(),
            languageOptions: {
                parser: /** @type {*} */ (jsoncParser),
            },
            plugins: {
                jsonc: /** @type {*} */ (jsoncPlugin),
            },
        },
        {
            files: [ '**/*.json' ],
            rules: /** @type {import('eslint').Linter.RulesRecord} */
                (jsoncPlugin.configs['recommended-with-json'].rules),
        },
        {
            files: [ '**/*.jsonc' ],
            rules: /** @type {import('eslint').Linter.RulesRecord} */
                (jsoncPlugin.configs['recommended-with-jsonc'].rules),
        },
        {
            files: [ '**/*.json5' ],
            rules: /** @type {import('eslint').Linter.RulesRecord} */
                (jsoncPlugin.configs['recommended-with-json5'].rules),
        },
    ];
}

You dont need to overlap the ts parser and the jsonc parser :)

@joeprivettsmart This one worked for me:

Exact answer (".eslintrc.js" config):

module.exports = {
  // ...
  overrides: [
    // ...
    {
      files: [ '**/locales/*.json' ],
      parser: "jsonc-eslint-parser",
      extends: [ 'plugin:jsonc/base' ],
      rules: {
        "jsonc/sort-keys": [
          "error",
          {
            pathPattern: ".*",
            order: { type: "asc", natural: true }
          },
        ],
      },
    },
  ],
}
