Create CI in 5 minutes for .Net Core & Angular using Azure DevOps

In this article, I will show how easy it is to create a CI for building and running tests for .Net Core & Angular application

What is Azure DevOps?

Azure DevOps is a SAAS CI software from Microsoft. It has a set of tool-chains for developing and deploying software.

You can create a free account and use up to 25 hours of build time for free for your project.

Create YAML file

Azure DevOps uses YAML files to control the pipeline. YAML is a human-readable data-serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted. 

You can create a new ” azure-pipelines.yml” file in the root directory of your project.

Choose OS to run

You can choose several OS to build your project. Usually, it is Windows or Linux.

For Linux it will be:

  vmImage: 'ubuntu-latest'

For Windows:

  vmImage: 'windows-latest'

Set a list of variables

It is usually a good practice to set a list of variables that you would like to use across the pipeline. Try not to hard-code values or duplicate them across your script. Example for variables section:

  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

Restore .Net Core project dependencies

To build a project we need to restore all of its dependencies first. NuGet is used for that. We basically need two steps here:

  1. Install NuGet
  2. Run it against a solution to restore dependencies
- task: NuGetToolInstaller@1

- task: NuGetCommand@2
    restoreSolution: ""

Build Solution

We can use a dotnet commands to build a solution

- script: dotnet build --configuration 
  displayName: 'Build .Net Solution'

Run Unit Tests

Unit tests run is an essential part of any CI process. We can use a dotnet command “test” for that and point it to the project with unit tests.

- task: DotNetCoreCLI@2
  displayName: 'Run Unit tests'
    command: test
    projects: '**/NUnitTests.csproj'
    arguments: '--configuration '

Restore Angular dependencies

Now let’s move to Angular. Firstly we need to restore dependencies. We can use a node package manager NPM to restore dependencies for our Angular project. Just point it to a folder where Angular code is located

- task: Npm@1
  displayName: 'Restore Angular Dependencies'
    workingDir: [solution_folder]/[angular_folder]
    verbose: false

Build Angular project

We can build Angular code with the same npm package manager. This is a script for that:

- task: Npm@1
  displayName: 'Build Angular'
    command: custom
    workingDir: [solution_folder]/[angular_folder]
    verbose: false
    customCommand: 'run build'

Run the Pipeline

That’s it! Use a created YAML file as an instructions for AzureDevops pipeline. After build is done you will receive a picture like that (depends on your steps). More information is available on Microsoft website with instructions for other languages (e.g. Java)
