Walkthrough

The pull request introduces a new .env.sample file outlining various environment variables for application configuration, including settings for authentication, database, and mail. It also adds a .env entry to .gitignore to prevent tracking of environment files. The package.json file is updated to include the dotenv dependency. Additionally, several files are modified to enhance documentation, improve error handling, and implement a graceful shutdown process, including the introduction of a Closable interface and a setupShutdownHandler function.

Changes

File	Change Summary
.env.sample	New file added with environment variable declarations for configuration settings.
.gitignore	Added .env to ignore files with the .env extension.
api/package.json	Added new dependency "dotenv": "^16.0.3" to manage environment variables.
api/src/app.module.ts	Updated JwtModule.register method parameter; enhanced JSDoc comments for configure and addPipesAndFilters.

api/src/types.ts	Added Closable interface for objects that can be closed gracefully.

Possibly related PRs

• [Fix] Jest Test e2e #402: The changes in the package.json file related to dependencies may indirectly connect to the main PR's introduction of the dotenv package, as both involve environment configuration, but there are no direct code-level changes that relate to the environment variables outlined in the main PR.

🐰 In the garden where secrets grow,
A new .env.sample starts to glow.
With tokens and ports, all set to play,
CORS and mail, in a neat array.
As we hop along, with graceful cheer,
Our app's now ready, the launch is near! 🌼

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
