The first VSCode Extension which can Validate and Expand Azure Pipeline YAML files locally without any REST service.
Live syntax checking for pipelines
Live preview of the expanded / rendered pipeline
Experimental autocompletion
slow ( disabled by default )
You can try this out by enabling setting azure-pipelines-vscode-ext.enable-auto-complete (no restart needed), feedback wanted.
Experimental semantic highlighting of template and runtime expressions
potentially slow ( disabled by default )
You can try this out by enabling setting azure-pipelines-vscode-ext.enable-semantic-highlighting (no restart needed), feedback wanted.
Features
Remote Template References
The azure-pipelines-vscode-ext.repositories settings maps the external Repositories to local or remote folders.
Syntax [<owner>/]<repo>@<ref>=<uri> per line. <uri> can be formed like file:///<folder> (raw file paths are not supported (yet?)), vscode-vfs://github/<owner>/<repository> and vscode-vfs://azurerepos/<owner>/<project>/<repository>
Check Syntax Azure Pipeline
> Check Syntax Azure Pipeline
This command explicitly checks for syntax errors in the yaml structure and expression syntaxes.
Referenced templates are read to apply the correct schema for their parameters, if this fails this check is disabled.
These are necessary but not sufficient checks for a successful Validation of an Azure Pipeline.
Validate Azure Pipeline
> Validate Azure Pipeline
Use this command on your entrypoint Pipeline, otherwise parameters may be missing
This command tries to evaluate your current open Azure Pipeline including templates and notifies you about the result.
Expand Azure Pipeline
> Expand Azure Pipeline
Use this command on your entrypoint Pipeline, otherwise parameters may be missing
This command tries to evaluate your current open Azure Pipeline including templates and show the result in a new document, which you can save or validate via the official api.
Azure Pipelines Linter Task
You can configure parameters, variables, repositories per task. You can define multiple tasks with different parameters and variables or filenames to catch errors on changing template files as early as possible.

Pro
- Make changes in multiple dependent template files and show a live preview
- Everything is done locally and works offline
- You can run template files with the same template engine locally via the Runner.Client and Server tool using the official Azure Pipelines Agent
Runner.Client azexpand -W azure-pipeline.yml works like Validate Azure Pipeline by only checking the return value to be zeroRunner.Client azexpand -q -W azure-pipeline.yml > final.yml works like Expand Azure Pipeline, but directly writes the expanded file to diskRunner.Client azpipelines -W azure-pipeline.yml to test Azure Pipelines locally via the official agent
--interactive and --watch allow to iterate even faster by keeping the local server and agent running
- Less trial and error commits
- Works side by side with the official Azure Pipelines VSCode extension
Contra
- May contain different bugs than the Azure Pipelines Service
- You can self-host Azure Devops Server and commit your changes to your local system with more accurate results of the template engine
- Missing predefined Variables, feel free to add them manually as needed
- Unsupported legacy syntax causes errors
Available in both VSCode Marketplace and Open VSX Registry
