Walkthrough

The pull request introduces a new type utility, IsAllOptional<T>, to evaluate whether all properties of a given object type are optional. It also defines a new API endpoint for user creation, specifying optional headers and body parameters. Additionally, the RequestInitT type is modified to enhance the handling of optional properties in both the body and headers of requests. These changes collectively improve type safety and flexibility in the codebase.

Changes

Files Change Summary
src/common/type.t-test.ts Added type IsAllOptional and type IsAllOptionalTestCases to test the new utility for evaluating optional properties in object types.
src/common/type.ts Introduced export type IsAllOptional<T> to determine if all properties of type T are optional using conditional types.
src/fetch/index.t-test.ts Defined a new POST request specification for the /users endpoint, detailing optional headers and body structure, along with a 200 response format.
src/fetch/index.ts Modified RequestInitT type to include conditional logic for body and headers, allowing for optional properties based on the IsAllOptional utility type.

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 generate interesting stats about this repository and render them as a table.
    -- @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.

30-34: LGTM!

The change to the body property of RequestInitT is logically correct and enhances flexibility by allowing it to be optional when all properties of Body are optional. This aligns with the PR objective of allowing to omit body if it is optional.


36-38: LGTM!

The change to the headers property of RequestInitT is logically correct and enhances flexibility by allowing it to be optional when all properties of HeadersObj are optional. This aligns with the PR objective of allowing to omit headers if it is optional.

src/common/type.ts (1)

145-147: LGTM!

The IsAllOptional<T> type is a useful addition to the type utilities. It correctly checks if all properties of a given type T are optional using a conditional type.

The static analysis hint about not using {} as a type can be safely ignored in this case because {} is intentionally used to check if all properties are optional.

6-6: LGTM!

The import statement for IsAllOptional is syntactically correct. It is likely used in the new code segment.


113-121: Comprehensive test cases for IsAllOptional.

The test cases cover various scenarios and ensure that the IsAllOptional type utility is working as expected. Great job on writing thorough tests!

146-161: LGTM!

The changes introduce a new specification for the /users endpoint with a POST method, allowing for optional headers and body. The async function demonstrates the correct usage of the fetch function with this new specification, omitting the headers and body as they are optional.

The changes enhance the API's functionality and provide flexibility in the usage of the endpoint.

Avoid using {} as a type.

The static analysis tool suggests not using {} as a type and explicitly defining the object shape instead. Using {} as a type could lead to unexpected behavior and make the code harder to understand and maintain.

Consider replacing {} with a more explicit type, such as Record<string, never>, to represent an empty object type.
