Azure Blob Storage File Merge Azure Function

🗂 An Azure Function to merge a group of JSON files from Azure Blob Storage and return the single merged file and write the merged file back to blob storage.

Requirements

• Microsoft Azure Account
• VS Code for Production Deployment and Local Development
• Azure Functions VS Code Extension for Local Development
• Node.js LTS Version

Installation

npm i -S joemccann/azure-blob-storage-file-merge

Create a .env file and include the following values:

AZURE_TENANT_ID=XXX
AZURE_CLIENT_ID=XXX
AZURE_CLIENT_SECRET=XXX
AZURE_STORAGE_CONTAINER=XXX
BLOB_SERVICE_ACCOUNT_NAME=XXX
FILENAME_PREFIX=OPTIONAL-PREFIX-FOR-FILES-IN-STORAGE-CONTAINER

Note: FILENAME_PREFIX is optional. If you include it, the merge will only files that begin with the FILENAME_PREFIX string like "daily-" or "contact-".

Create a local.settings.json file as well for running the Azure Function locally in VS Code.

If you don't know where to obtain these values in Azure, look at the AZURE.md document.
