Parse Server is a self-hostable, open-source backend for applications, providing a compatible API for the Parse platform SDKs. It enables developers to migrate their applications from the hosted Parse.com service (which was deprecated) to their own infrastructure, offering full control over their data and backend logic. The current stable version is 9.8.0. The project maintains an active development pace with frequent alpha releases for new features and bug fixes, typically leading to stable minor versions every few weeks or months. Key differentiators include its adherence to the Parse API specification, allowing seamless migration, extensive customization via Cloud Code and webhooks, and flexible database support (primarily MongoDB and PostgreSQL). It integrates directly with Express.js, making it easy to embed into existing Node.js applications.
npm install parse-serverVerified import paths — ran on the pinned version, not inferred.
Sets up a basic Parse Server instance with Express.js, connecting to a MongoDB database, enabling Cloud Code, Live Queries, and a basic email adapter for user verification.
Upgrade to `parse-server@9.8.0` or higher immediately. Review and adapt any client-side or cloud code logic that might have been exploiting previous unprotected field access.
Ensure your Node.js environment strictly adheres to the `engines.node` specification in `package.json`. Use a tool like `nvm` to manage and switch Node.js versions as needed.
Only use the `masterKey` in secure server-side environments (e.g., Cloud Code, administrative scripts). Never include it in frontend applications or expose it via APIs. Implement granular ACLs/CLPs for client operations.
Implement a deployment strategy that restarts the Parse Server process after Cloud Code changes. For development, consider using `nodemon` or similar tools for automatic restarts on file changes.
Regularly review your authentication provider configurations (e.g., Facebook, Google, Apple) and update them according to the latest Parse Server and provider-specific documentation. Keep your `parse-server` package updated.
Ensure MongoDB is running and accessible from the Parse Server host. Verify the `databaseURI` in your Parse Server configuration (e.g., `mongodb://localhost:27017/yourdbname`).
Double-check that the `appId` value in your Parse Server configuration (e.g., `new ParseServer({ appId: 'YOUR_APP_ID' })`) is identical to the one your Parse SDK client uses to initialize.Verify that your Cloud Code file (e.g., `cloud/main.js`) contains `Parse.Cloud.define('myCloudFunction', ...)` and that the `cloud` option in your Parse Server configuration points to the correct path.Ensure `parseServerApi.app` is accessed only after `new ParseServer` has completed its initialization. Confirm all required configuration options (e.g., `appId`, `masterKey`, `databaseURI`) are provided.
