Hello @davidcavazos, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

Hello! Gemini here, providing a summary of this pull request. This PR, authored by davidcavazos, aims to address potential CJS (CommonJS) errors encountered by the ai-platform/snippets tests by migrating their CI environment to use Node.js version 16. This change involves updating the CI configuration files to reflect the new testing setup, creating a dedicated CI configuration file for the snippets, updating package dependencies, and migrating the test files from require syntax (CJS) to import syntax (ESM).

Highlights

• CI Node Version Downgrade: The primary goal is to run the ai-platform/snippets tests using Node.js 16 instead of a newer version, specifically to mitigate issues related to CJS module compatibility.
• CI Configuration Updates: The .github/config/nodejs.jsonc and .github/config/nodejs-dev.jsonc files are updated to remove ai-platform/snippets from the list of failing/skipped tests in the main Node.js CI run and add it to the list of tests skipped in the dev CI run (as it will now pass in the dedicated prod CI run).
• Dedicated CI Setup File: A new file, ai-platform/snippets/ci-setup.json, is added to define the specific CI environment for these snippets, explicitly setting the node-version to "16" and configuring secrets and timeout.
• Dependency Updates: The ai-platform/snippets/package.json file sees updates to several dependencies, including @google-cloud/aiplatform, @google-cloud/bigquery, chai, mocha, uuid, and sinon. The test script is also modified to use the --reporter list flag.
• ESM Import Migration: Test files (batch-prediction-gemini.test.js and create-batch-prediction-job-text-classification.test.js) are updated to use ES module import syntax instead of CommonJS require.

Code Review

This pull request aims to migrate the ai-platform/snippets to Node.js 16, primarily to resolve CJS (CommonJS) errors previously encountered. The changes involve CI configuration updates, significant dependency upgrades, and modernization of test files to use ES Module (ESM) syntax.

Overall, the changes appear to be well-executed and align with the stated goal. The move to Node 16 for this specific package, along with dependency updates and ESM adoption in tests, seems like a pragmatic approach to address the CI issues.

Summary of Findings

• Node.js Version Downgrade/Pinning: The CI configuration for ai-platform/snippets is now explicitly set to use Node.js 16 via the new ai-platform/snippets/ci-setup.json file. This is the core change to address the CJS errors.
• Dependency Upgrades: Several key dependencies (@google-cloud/aiplatform, @google-cloud/bigquery) and devDependencies (chai, mocha, uuid, sinon) have been upgraded to newer major versions in ai-platform/snippets/package.json. These updates likely contribute to better compatibility with Node 16 and ESM.
• Test Syntax Modernization: Test files (batch-prediction-gemini.test.js, create-batch-prediction-job-text-classification.test.js) have been refactored from CommonJS (require) to ES Module (import) syntax. This aligns with modern JavaScript practices and is often necessary with newer library versions and Node.js ESM support.
• CI Test Configuration Update: The ai-platform/snippets tests are now skipped in the dev CI environment (as per .github/config/nodejs-dev.jsonc) because they are reportedly passing in production, and removed from the "TODO: fix these" list in .github/config/nodejs.jsonc, indicating the underlying issues are resolved.
• Mocha Reporter Update: The test script in package.json now uses --reporter list for Mocha, which should improve the readability of test outputs in CI.

Merge Readiness

The changes in this pull request seem to correctly implement the goal of migrating ai-platform/snippets to Node.js 16 and addressing related CJS errors. The dependency upgrades and ESM syntax adoption in tests are logical steps in this process. Based on the code review, no critical or high-severity issues were identified in the implementation itself. The PR appears to be in good shape for merging, assuming CI checks pass and the 'experiment' is deemed successful. As a reviewer, I cannot approve the PR, but it seems technically sound.

[davidcavazos]

Looks like the "node-version" feature is not yet implemented in custard-run.yaml, and it doesn't seem to be working properly on the legacy custard-ci.yaml either.
