Linting a single file is super slow

[kevinbarabash]

Here's a paired down config:

module.exports = {
    parserOptions: {
        schema: pathToSchemaFile,
        schemaOptions: {
            assumeValid: true,
        },
        operations: "javascript/**/*.{ts,tsx}",
    },
    overrides: [
        {
            files: ["*.ts", "*.tsx"],
            processor: "@graphql-eslint/graphql",
        },
        {
            files: ["*.graphql"],
            parser: "@graphql-eslint/eslint-plugin",
            plugins: ["@graphql-eslint"],
            rules: {
                "@graphql-eslint/known-type-names": "error",
                // "@graphql-eslint/unique-operation-name": "error",
                "@graphql-eslint/require-id-when-available": [
                    "error",
                    {fieldName: ["id", "cacheId"]},
                ],
                "prettier/prettier": "off",
            },
        },
    ],
}

I'm running eslint using the following command:

eslint --debug --ext .js --ext .jsx --ext .ts --ext .tsx --ext .graphql --quiet javascript/cp-shared-package/revision-history-modal.tsx

I'm seeing the following output:

followed by thousands of lines of similar output. It looks like it's parsing every single .ts(x) file in my project. Is there a way to keep it from doing this?

I'm in the wrong repo. Sorry about that.

By removing the operations property, you ensure that the GraphQL ESLint parser only targets .graphql files. The .ts and .tsx files will be handled by the processor defined for those file types.

However, if you still encounter the issue of parsing all .ts and .tsx files, you might need to check other parts of your ESLint or project configuration that could be inadvertently triggering this behavior.
