Question 1

How to use file-changes-action to deploy only changed services?

Accepted Answer

Set up the action in your workflow to output changed files, then use conditional steps (e.g., 'if' conditions in jobs) to deploy based on file paths. For example, check if files in a service directory are in the 'files_modified' output to trigger its deployment.

Question 2

file-changes-action vs GitHub's built-in paths filter in workflows?

Accepted Answer

file-changes-action provides detailed file lists for custom logic (e.g., outputting JSON arrays), while GitHub's paths filter is simpler for triggering entire jobs. Use this action when you need to know exactly which files changed for complex conditional steps within a job.

Question 3

How to output file changes as a CSV file in GitHub Actions?

Accepted Answer

Set the 'fileOutput' input to ',' to generate CSV files. The action will create files like $HOME/files.csv with comma-separated file names, as demonstrated in the README examples.

Question 4

Can file-changes-action compare changes across different branches?

Accepted Answer

Yes, by using the 'pushBefore' and 'pushAfter' inputs with specific commit SHAs from different branches, you can compare any two commits. However, this requires manual SHA specification and isn't automated for branch comparisons.

Question 5

Does file-changes-action work with private repositories?

Accepted Answer

Yes, but you need to provide a GitHub token with 'repo' scope via the 'githubToken' input. The default GITHUB_TOKEN may not have sufficient permissions for private or cross-repo access.

Question 6

How to avoid rate limiting with file-changes-action?

Accepted Answer

Use a fine-grained personal access token with minimal permissions and cache results if possible. The action makes API calls for each run, so in high-frequency workflows, consider batching or using GitHub's caching features to reduce calls.
