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.
