Question 1

How do I resolve custom !include tags in YAML?

Accepted Answer

To resolve custom !include tags, simply paste your primary YAML configuration into our editor. You can then define the associated mock content in the side panel for each path mentioned in your !include statements, and the application will automatically merge them into a single, valid output.

This process ensures that your multi-file YAML structures are flattened into a readable, coherent document. It is specifically designed for developers working on configuration management or infrastructure-as-code who need to visualize the final merged output before finalizing their deployments.

Question 2

Is this YAML resolver secure to use with sensitive data?

Accepted Answer

Yes, this tool operates entirely on the client side. Your data never leaves your browser, and absolutely no server-side processing or storage occurs. We do not transmit your YAML files over the network, making it a secure choice for handling private or proprietary configuration files without the risk of data leakage.

Because the processing occurs locally within your browser's memory, you can safely use this tool even in offline environments. We strictly avoid using local storage, cookies, or external databases, ensuring complete data privacy and security for every user session.

Question 3

Can I mock complex, nested file structures?

Accepted Answer

Absolutely. You can define multiple mock files within our interface, and the resolver will map your !include commands to the corresponding mock content provided in the UI. You are free to create deep, nested structures to test how your logic handles hierarchical imports.

This capability is particularly useful for debugging large configuration sets like Kubernetes manifests or environment templates where manual resolution is error-prone. By visualizing the final merged state, you can catch syntax errors or structural issues instantly, saving significant debugging time.

Question 4

Does this tool provide validation for the resolved YAML?

Accepted Answer

Yes, once the !include tags are resolved and the files are merged, our engine performs a real-time syntax validation check on the resulting output. If the merged YAML contains any indentation or structural errors, the tool will highlight the problematic lines, allowing you to quickly rectify syntax issues.

This dual functionality—merging and validating—streamlines your development workflow. You no longer need to switch between different tools to parse your custom tags and verify the final syntax, as this application provides an all-in-one environment for your configuration testing needs.
