API Support for Bulk Suppressions

ESLint v10.1.0 introduces API support for the bulk suppressions feature that was previously only available in the CLI.

ESLint API consumers, such as IDEs, can now pass the applySuppressions: true option to the ESLint constructor. With this option, suppressions from the suppressions file are automatically applied to results from ESLint#lintFiles() and ESLint#lintText() methods.

const eslint = new ESLint({
  applySuppressions: true,

  // optional, defaults to `eslint-suppressions.json`
  suppressionsLocation: "./config/my-suppressions.json",
});

Please see the Bulk Suppressions - Usage with the Node.js API section for more details.
