This repo contains sample code for a simple chat webapp that integrates with Azure OpenAI. Note: some portions of the app use preview APIs.
- An existing Azure OpenAI resource and model deployment of a chat model (e.g.
gpt-35-turbo-16k
,gpt-4
) - To use Azure OpenAI on your data, one of the following data sources:
- Azure AI Search Index
- Azure CosmosDB Mongo vCore vector index
- Elasticsearch index (preview)
- Pinecone index (private preview)
- Azure SQL Server (private preview)
Follow instructions below in the app configuration section to create a .env file for local development of your app. This file can be used as a reference to populate the app settings for your Azure App Service deployed webapp.
After creating your .env file, run one of the following commands in your preferred shell to create a JSON representation of your environment which is recognized by Azure App Service.
Get-Content .env | ForEach-Object {Â
    if ($_ -match "(?<name>[A-Z_]+)=(?<value>.*)") {Â
        [PSCustomObject]@{Â
            name = $matches["name"]Â
            value = $matches["value"]Â
            slotSetting = $false
        }
   }
} | ConvertTo-Json | Out-File -FilePath env.json
cat .env | jq -R '. | capture("(?<name>[A-Z_]+)=(?<value>.*)")' | jq -s '.[].slotSetting=false' > env.json
Please see README_azd.md for detailed instructions.
Click on the Deploy to Azure button and configure your settings in the Azure Portal as described in the Environment variables section.
Please see the section below for important information about adding authentication to your app.
-
Follow the steps below in the app configuration section to construct your .env file with the appropriate variables for your use case.
-
Start the app with
start.cmd
. This will build the frontend, install backend dependencies, and then start the app. Or, just run the backend in debug mode using the VSCode debug configuration in.vscode/launch.json
. -
You can see the local running app at https://127.0.0.1:50505.
NOTE: You may find you need to set: MacOS: export NODE_OPTIONS="--max-old-space-size=8192"
or Windows: set NODE_OPTIONS=--max-old-space-size=8192
to avoid running out of memory when building the frontend.
NOTE: If you've made code changes, be sure to build the app code with start.cmd
or start.sh
before you deploy, otherwise your changes will not be picked up. If you've updated any files in the frontend
folder, make sure you see updates to the files in the static
folder before you deploy.
You can use the Azure CLI to deploy the app from your local machine. Make sure you have version 2.48.1 or later.
If this is your first time deploying the app, you can use az webapp up. Run the following command from the root folder of the repo, updating the placeholder values to your desired app name, resource group, location, and subscription. You can also change the SKU if desired.
az webapp up --runtime PYTHON:3.11 --sku B1 --name <new-app-name> --resource-group <resource-group-name> --location <azure-region> --subscription <subscription-name>
Note: if using the Azure CLI version 2.62 or greater, you may also want to add the flag --track-status False
to prevent the command from failing due to startup errors. Startup errors can be solved by following the instructions in the next section about updating app configuration.
After creating your Azure App Service, follow these steps to update the configuration to allow your application to properly start up.
- Set the app startup command
az webapp config set --startup-file "python3 -m gunicorn app:app" --name <new-app-name>
- Set
WEBSITE_WEBDEPLOY_USE_SCM=false
to allow local code deployment.
az webapp config appsettings set -g <resource-group-name> -n <existing-app-name> --settings WEBSITE_WEBDEPLOY_USE_SCM=false
- Set all of your app settings in your local .env file at once by creating a JSON representation of the .env file, and then run the following command.
az webapp config appsettings set -g <resource-group-name> -n <existing-app-name> --settings "@env.json"
Check the runtime stack for your app by viewing the app service resource in the Azure Portal. If it shows "Python - 3.10", use PYTHON:3.10
in the runtime argument below. If it shows "Python - 3.11", use PYTHON:3.11
in the runtime argument below.
Check the SKU in the same way. Use the abbreviated SKU name in the argument below, e.g. for "Basic (B1)" the SKU is B1
.
Then, use these commands to deploy your local code to the existing app:
az webapp up --runtime <runtime-stack> --sku <sku> --name <existing-app-name> --resource-group <resource-group-name>
az webapp config set --startup-file "python3 -m gunicorn app:app" --name <existing-app-name>
Make sure that the app name and resource group match exactly for the app that was previously deployed.
Deployment will take several minutes. When it completes, you should be able to navigate to your app at {app-name}.azurewebsites.net.
After deployment, you will need to add an identity provider to provide authentication support in your app. See this tutorial for more information.
If you don't add an identity provider, the chat functionality of your app will be blocked to prevent unauthorized access to your resources and data.
To remove this restriction, you can add AUTH_ENABLED=False
to the environment variables. This will disable authentication and allow anyone to access the chat functionality of your app. This is not recommended for production apps.
To add further access controls, update the logic in getUserInfoList
in frontend/src/pages/chat/Chat.tsx
.
To enable Microsoft Entra ID for intra-service authentication:
- Enable managed identity on Azure OpenAI
- Configure AI search to allow access from Azure OpenAI
- Enable Role Based Access control on the used AI search instance (see documentation)
- Assign
Search Index Data Reader
andSearch Service Contributor
to the identity of the Azure OpenAI instance
- Do not configure
AZURE_SEARCH_KEY
andAZURE_OPENAI_KEY
to use Entra ID authentication. - Configure the webapp identity
- Enable managed identity in the app service that hosts the webapp
- Go to the Azure OpenAI instance and assign the role
Cognitive Services OpenAI User
to the identity of the webapp
Note: RBAC assignments can take a few minutes before becoming effective.

should be added to the public folder before building the project. The Vite build process will automatically copy theses files to the static folder on each build of the frontend. The corresponding environment variables should then be set using a relative path such as static/<my image filename>
to ensure that the frontend code can find them.
Feel free to fork this repository and make your own modifications to the UX or backend logic. You can modify the source (frontend/src
). For example, you may want to change aspects of the chat display, or expose some of the settings in app.py
in the UI for users to try out different behaviors. After your code changes, you will need to rebuild the front-end via start.sh
or start.cmd
.
You can configure the number of threads and workers in gunicorn.conf.py
. After making a change, redeploy your app using the commands listed above.
See the Oryx documentation for more details on these settings.
First, add an environment variable on the app service resource called "DEBUG". Set this to "true".
Next, enable logging on the app service. Go to "App Service logs" under Monitoring, and change Application logging to File System. Save the change.
Now, you should be able to see logs from your app by viewing "Log stream" under Monitoring.
The Citation panel is defined at the end of frontend/src/pages/chat/Chat.tsx
. The citations returned from Azure OpenAI On Your Data will include content
, title
, filepath
, and in some cases url
. You can customize the Citation section to use and display these as you like. For example, the title element is a clickable hyperlink if url
is not a blob URL.
<h5
className={styles.citationPanelTitle}
tabIndex={0}
title={activeCitation.url && !activeCitation.url.includes("blob.core") ? activeCitation.url : activeCitation.title ?? ""}
onClick={() => onViewSource(activeCitation)}
>{activeCitation.title}</h5>
const onViewSource = (citation: Citation) => {
if (citation.url && !citation.url.includes("blob.core")) {
window.open(citation.url, "_blank");
}
};
We recommend keeping these best practices in mind:
- Reset the chat session (clear chat) if the user changes any settings. Notify the user that their chat history will be lost.
- Clearly communicate to the user what impact each setting will have on their experience.
- When you rotate API keys for your AOAI or ACS resource, be sure to update the app settings for each of your deployed apps to use the new key.
- Pull in changes from
main
frequently to ensure you have the latest bug fixes and improvements, especially when using Azure OpenAI on your data.
A note on Azure OpenAI API versions: The application code in this repo will implement the request and response contracts for the most recent preview API version supported for Azure OpenAI. To keep your application up-to-date as the Azure OpenAI API evolves with time, be sure to merge the latest API version update into your own application code and redeploy using the methods described in this document.
