### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/azure/events/blobstorage) # Blob Storage Trigger Azure Functions Blob Storage trigger lets you listen on Azure Blob Storage. Full documentation can be found on [azure.com](https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob). ## Blob Storage Events ### Blob Storage Trigger This setup specifies that the `hello` function should be run when a new Blob Storage item appears on the blob container "hello/{name}", where `{name}` is the name of the blob uploaded.. Here's an example: ```yml # serverless.yml functions: example: handler: handler.hello events: - blob: name: item #, default - "myBlob", specifies which name is available on `context.bindings` path: hello/{name} connection: AzureWebJobsStorage #, default - "AzureWebJobsStorage", App Setting/environment variable which contains Storage Account Connection String ``` ```javascript // handler.js 'use strict'; module.exports.hello = function (context, item) { context.log('Received item: ${item}'); context.done(); }; ```
