Your Notion API integration token. * - NOTION_MARKDOWN_CONVERSION: Optional. Set to "true" to enable * experimental Markdown conversion. If not set or set to any other value, * all responses will be in JSON format regardless of the "format" parameter. */ import yargs from "yargs"; import { hideBin } from "yargs/helpers"; import { startServer } from "./server/index.js"; // Parse command line arguments const argv = yargs(hideBin(process.argv)) .option("enabledTools", { type: "string", description: "Comma-separated list of tools to enable", }) .parseSync(); const enabledToolsSet = new Set( argv.enabledTools ? argv.enabledTools.split(",") : [] ); // if test environment, do not execute main() if (process.env.NODE_ENV !== "test" && process.env.VITEST !== "true") { main().catch((error) => { console.error("Fatal error in main():", error); process.exit(1); }); } async function main() { const notionToken = process.env.NOTION_API_TOKEN; const enableMarkdownConversion = process.env.NOTION_MARKDOWN_CONVERSION === "true"; if (!notionToken) { console.error("Please set NOTION_API_TOKEN environment variable"); process.exit(1); } await startServer(notionToken, enabledToolsSet, enableMarkdownConversion); }
