Key Takeaways
- DigitalRGS MongooseLTR app installation simplifies MongoDB log replication with easy integration into Node.js and Mongoose projects.
- Ensure system prerequisites like Node.js v16+, MongoDB 5.0+, and sufficient RAM and disk space before starting installation.
- Follow a clear, step-by-step installation process: clone repo, install dependencies, configure environment variables, initialize schema, and run smoke tests.
- Configure environment variables properly with MONGO_URI and LTR_ENABLED to enable logging and verify setup with test scripts.
- Perform post-install verification by inserting and updating documents to ensure logs are correctly recorded and streaming functions as expected.
- Address common errors by checking MongoDB connections, package installation, log settings, and version compatibility to maintain smooth operation.
Why Choose DigitalRGS MongooseLTR For Your App
DigitalRGS MongooseLTR offers a focused set of features for apps that use MongoDB and require log replication. The package integrates with Node.js and Mongoose. It reduces time to carry out change tracking and log-based read replicas. Developers pick digitalrgs mongooseltr app installation when they want a lightweight, schema-aware logging layer. It fits local development and staging environments. The library keeps API calls simple and minimizes overhead. Teams that need quick audit trails and simple replica feeds benefit from using it.
Prerequisites And System Requirements
The installer requires Node.js v16 or later and npm or yarn. The system needs MongoDB 5.0 or higher for change stream stability. The host must have 2 GB free RAM and 1 GB disk for logs. The user needs shell access and rights to create databases. The developer requires a valid project with Mongoose installed. For CI, the pipeline must allow environment variables and secret injection. Confirm the network allows connections to the MongoDB host and any remote services used by the app. Verify these items before starting the digitalrgs mongooseltr app installation.
Step-By-Step Installation Guide
Follow these steps to complete the digitalrgs mongooseltr app installation. The steps assume a Unix-like shell. 1) Clone the project repository. 2) Install dependencies. 3) Configure environment variables. 4) Initialize the database schema. 5) Start the service and run smoke tests. Each step below shows commands and expected results. Keep logs for debugging.
Install Dependencies And Local Environment Setup
Open the project folder and install packages. Run: npm install or yarn install. Ensure Mongoose is present. Run: npm list mongoose. If the command returns a version, proceed. Add digitalrgs mongooseltr via npm: npm install digitalrgs-mongooseltr –save. Create a local .env file with NODE_ENV and MONGO_URI values. Start a local MongoDB instance or use a Docker container. Use: docker run -d -p 27017:27017 –name mdb mongo:5. After the container runs, check the connection with a simple Mongoose script. This step readies the environment for the installation.
Configure The App, Environment Variables, And Database Connection
Edit config files to add the digitalrgs mongooseltr settings. Set MONGO_URI, LTR_ENABLED=true, and LTR_LOG_COLLECTION. In code, require the module and pass the Mongoose instance. Example: const mongoose = require(‘mongoose’): const ltr = require(‘digitalrgs-mongooseltr’)(mongoose): Initialize the module after the connection opens. Create indexes on the log collection for timestamp and document id. Verify credentials and network access. Run a short script that writes a test document and checks the LTR collection for a log entry. This confirms the digitalrgs mongooseltr app installation completed configuration.
Post-Install Verification And Basic Smoke Tests
Run a set of tests to confirm the digitalrgs mongooseltr app installation worked. Test 1: Insert a document and check the log collection for a matching record. Test 2: Update a field and confirm a new log entry appears. Test 3: Restart the app and verify the module reattaches and continues logging. Use logging at info level to capture actions. Check for dropped events or errors. If the app exposes a health endpoint, call it and assert 200 OK. If the app streams to a client, confirm streaming works on mobile and streaming apps by testing playback on a device with the same network.
Common Installation Errors And How To Fix Them
Error: Connection refused. Fix: Verify MONGO_URI, start MongoDB, and open the port. Error: Module not found. Fix: Run npm install digitalrgs-mongooseltr and confirm node_modules contains the package. Error: Missing logs. Fix: Ensure LTR_ENABLED=true and check index permissions on the log collection. Error: High latency. Fix: Move the DB closer to the app and enable indexes. Error: Version mismatch. Fix: Upgrade Node.js or MongoDB to supported versions. For permission or network claims, consult the platform docs for connection details to resolve host-level blocks.
