generator-azure-web-app
Minimalist Azure Web App generator: Webpack/Rollup + React + Express, deployable to standalone Node.js, Azure App Service, and IIS.
Why us?
Modern websites are not just bunches of plain text files. Build process increases page load efficiency and overall page performance.
But everyone build and promote their own build process. There are few reasons you should choose us:
- Scaffold with Yeoman,
yo azure-web-app
- Choose your own faith: we only include React
- Bundle with the best bundler
- Webpack for development, hot module replacement means less page refresh
- Optionally, Rollup for production, better tree-shaking algorithm means smaller file size
- Support multiple deployment scenarios
Try it out in 3 easy steps
- Fork this repository
- Click
- Push your changes and see it continuously deploy to Azure
It takes about 5-10 minutes for the first build, have a little patience.
How to develop professionally
- Create a new Web App project
- Run local development server
- Develop locally
- Prepare for production deployment
- Deploy to target servers
- Update the scaffolding
Create a new Web App Project
For the very first time, run npm install -g yo generator-azure-web-app
to install Yeoman and our scaffolding.
Run yo azure-web-app
to create a new project.
Run local development server
Run npm start
, the development server will listen to port 80 and available at http://localhost/.
To change the port to 8080, either set environment variable PORT
to 8080
, or run npm start -- --port 8080
.
Develop locally
If you added new packages or modified server code, don't forget to restart the development server to pick up new changes.
Prepare for production deployment
Run npm run build
, to bundle JavaScript files, crush images, etc. It outputs to dist/website/
.
Optional: Using Rollup as bundler in production mode
Instead of Webpack used in development, you can opt for Rollup as bundler for production, it has better tree-shaking mechanism, thus smaller output file size.
Using rollup as bundler is experimental. Please file us an issue if you run into any problems.
There are few ways to select your bundler:
- Run
npm run build -- --bundler rollup
for one-time switch - Set environment variable
NPM_CONFIG_BUNDLER
to rollup
or webpack
- Modify
.npmrc
and set bundler = "rollup"
- During Yeoman scaffold, set bundler to
rollup
Deployment
The project supports multiple deployment scenarios, we will cover each separately.
Don't forget to build your project before deployment, run npm run build
.
Deploy as a standalone Node.js
Run node dist/website/index.js
to run as a standalone Node.js.
To deploy to your SaaS provider, copy everything under dist/website/
to your provider.
Deploy to Azure App Service
Azure App Service support continuous deployment or traditional MSDeploy. For small teams, we recommend continuous deployment.
Thru continuous deployment
Azure Web App comes with handy continuous deployment feature. When you push/save your code, Azure Web App will pickup new changes from GitHub, local Git (hosted on Azure), Dropbox, OneDrive, etc.
Follow steps below for first time setup for GitHub deployment.
- Commit your project to GitHub as a public repository
- Browse on GitHub
- Click
When deploying using continuous deployment, the project will build on Azure via Project Kudu.
Because the build is done on Azure, we modified the virtual path from /site/wwwroot
to /site/wwwroot/dist/website
. This is done by customizing azuredeploy.json
.
Currently, the "Deploy to Azure" service will not automatically setup webhooks on GitHub, thus, new commits do not re-sync automatically. To enable continuous deployment, go to Azure Portal and re-add GitHub deployment option.
Thru Visual Studio Team Services
Deploy thru Azure continuous deployment is limited and asynchronous. This makes the option unideal for medium or large teams.
We recommend VSTS Release Management for advanced deployment, it also comes with BVTs, performance tests, approval process, rollback, etc.
You can follow steps for VSTS here for advanced deployment scenario.
Thru MSDeploy
If you use CI/CD tools other than Azure and VSTS, you may want to integrate with MSDeploy.
- Run
npm run build
to build the project - Run
npm run pack
to pack the deployment as a MSDeploy ZIP file - Download publish settings file, either from Azure Dashboard or using Azure PowerShell
- Run
npm run deploy -- --publish-settings=yoursite.PublishSettings
to deploy with MSDeploy
To use a specific version of Node.js, don't forget to modify iisnode.yml
manually.
Deploy to Docker
We have prepared Dockerfile for deploying to Docker. Depends on your scenario, you can select one of the supported image types:
Run docker build .
at the project root to build your docker image.
Deploy to IIS
You can also deploy the project to an on-premise or hosted IIS.
- Make sure Node.js and iisnode is installed on the target server
- Run
npm run pack
to pack the deployment as a MSDeploy ZIP file - Use MSDeploy to deploy your package
The following MSDeploy command-line switches can be used to deploy the package to an IIS box.
"C:\Program Files (x86)\IIS\Microsoft Web Deploy V3\msdeploy.exe"
-verb:sync
-source:package="dist\packages\web.zip"
-dest:
auto,
ComputerName="https://<server>:443/msdeploy.axd?site=<appname>",
UserName='<username>',
Password='<password>',
AuthType='Basic'
-setParam:name="IIS Web Application Name",value="<appname>"
Update the scaffolding
We update our scaffolding from time to time. To update your existing project, rerun yo azure-web-app
and scaffold again. Yeoman will automatically download the latest scaffolding from npm.
Don't worry, Yeoman will prompt to overwrite a file if it should be replaced.
Support Internet Explorer 8
Although the user base of IE8 is fading, in some cases, you may still need to support older browsers.
Disable hot module replacement on development server
Run npm start -- --hot false
to start a development server without hot module replacement.
Use react@^0.14
and add es5-shim
You can copy the following code into index.html
.
<script src="https://cdnjs.cloudflare.com/ajax/libs/es5-shim/4.5.9/es5-shim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/es5-shim/4.5.9/es5-sham.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/console-polyfill/0.2.3/index.min.js"></script>
<script src="https://unpkg.com/react@0.14/dist/react.min.js"></script>
<script src="https://unpkg.com/react-dom@0.14/dist/react-dom.min.js"></script>
Look for IE8-friendly NPM packages
Some NPM packages are not IE8 friendly. For example, fetch
does not support IE8. You may need to use fetch-ie8
instead.
Moreoever, some packages might be pre-transpiled, they might not have reserved keywords properly escaped. There are two ways to tackle this issue:
- Contact package developer and kindly ask them to either
- Add
module
in package.json
and reference to non-transpiled version of code, or, - Escape reserved keywords during transpilation
- Use Webpack instead of Rollup: our Webpack workflow is configured to escape reserved keywords even in
node_modules/
folder
Roadmap
These are items we are working on or under consideration:
Roadblocks
It is not an easy task to build a scaffolding that support lots of deployment scenarios. You can find all the roadblocks here.
FAQs
- After deploying to Azure Web App, it say directory browsing is not allowed.
- During first deployment, do not browse to the web site until the deployment is ready. Otherwise, it will show 404, until you restart the server.
- How about CSS/LESS/SASS?
- We believe bundler should only bundle JS files and not CSS or other assets. Thus, we did not preconfigure the scaffolding with
style-loader
- For modern CSS inlining, we prefer
glamor
or aphrodite
. Please note that IE8 might not work with these modern CSS inliners

Working on this scaffolding
If you want to develop or debug this scaffolding, follow these steps:
- Run
npm uninstall generator-azure-web-app -g
to uninstall any installed scaffolding - Run
git clone https://github.com/compulim/generator-azure-web-app.git
to clone the repository - Run
npm link .
to link-install this copy, instead of the official one from npm registry
Next time, when you run Yeoman to generate a new azure-web-app
project, it will use your copy of scaffolding you cloned.
