Tips on executing npm commands on Azure app service following a successful deployment via VSTS?

While I've successfully deployed from VSTS to Azure, I'm facing an issue with running npm after the deploy is complete.

The current process involves running npm install for branch files, zipping them, copying to Azure, and deploying.

However, I'd like to add npm run custom-comand at the end of this chain. How can I achieve this?

Answer №1

The latest update to the VSTS Azure App Service Deployment task now includes a feature for post-deployment scripts. Take a look at this image from version 3.* of the task:

For more information on the task parameters, consult the Task Parameters section.

Attention Windows App Services users: Be cautious of a known npm bug that can cause issues with running multiple npm commands (either in-line or in a script). For instance:

npm install
npm test

In this case, only npm install will be executed. There are various workarounds available, such as using this solution:

npm install & npm test

Answer №2

If you are looking to implement a specific feature, there is no pre-built task available for that purpose. However, there are alternative methods you can use to run npm from Azure App Service:

Manual method: Access the Kudu console of your App Service and execute the npm command directly. You can follow this guide for assistance:https://i.stack.imgur.com/kroHq.png

Automatic method: Create a custom build task to run the npm command using the Kudu Rest API

Answer №3

If you want to execute commands like npm install using the Kudu REST API, it is possible.

For a PowerShell scripted example, check out this link: PowerShell Script Example .

To implement this in your build pipeline, ensure that you add a PowerShell script task post the Azure App Service Deploy task to trigger npm install. Make sure to disable the default npm install task in your build pipeline.

Answer №4

App Service makes use of the powerful Kudu deployment engine, which offers the capability to run custom deployment scripts. By embedding your npm command within a custom deployment script, it will automatically execute during the Azure deployment process. This eliminates the need for REST API calls and ensures that everything remains within your source control system.

Answer №5

Executing npm commands can be done using either the PowerShell task or the npm task.

Don't forget to include the .npmrc file with the authentication token when uploading to Azure.
