1712-1714: Improved clarity on Content-Type header setting

The documentation now correctly states that the Content-Type is set based on the file extension or format, rather than just the filename's extension. This provides a more accurate description of how the Content-Type is determined.


1728-1728: Updated default values in SendFile configuration

The documentation for the SendFile configuration struct has been improved by consistently using the term "Default" for default values of various fields. This enhances readability and maintains consistency throughout the documentation.

Also applies to: 1733-1733, 1738-1738, 1744-1744, 1750-1750


1764-1767: Added example for disabling compression

A new example has been added to demonstrate how to disable compression when using SendFile. This provides users with a clear illustration of how to customize the SendFile behavior.


1786-1789: Added examples for different SendFile configurations

Multiple examples have been added to showcase various SendFile configurations, including using different filesystems and compression settings. This helps users understand how to use SendFile with different options in a single route.

Also applies to: 1800-1803, 1804-1808, 1809-1812

ctx_test.go (1)

3126-3167: Well-structured test cases improve SendFile content type validation

The newly added Test_Ctx_SendFile_ContentType function comprehensively tests how the SendFile method determines the Content-Type header based on various file scenarios. The inclusion of tests for files with valid extensions, invalid extensions, and no extension enhances the robustness of the test suite.

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.

🧹 Outside diff range and nitpick comments (3)
router.go (2)

55-55: Approved: Improved consistency in documentation

The change from "Case sensitive param keys" to "Case-sensitive param keys" improves the consistency and correctness of the documentation. This aligns well with the PR objectives of fixing typos and improving clarity.


319-319: Approved: Improved clarity and consistency in comment

The change from "in-case sensitive" to "in case-sensitive" improves the grammatical correctness and consistency of the comment. This aligns well with the PR objectives of improving clarity and fixing typos.

For even better clarity, consider rephrasing the comment as follows:

		// Create a stripped path for case-sensitive routing and trailing slash handling

This suggestion more explicitly states the purpose of the stripped path creation.

ctx.go (1)

1500-1503: Approved: Documentation improvements for SendFile method

The updates to the SendFile method's documentation are clear and helpful. They address the PR objectives by clarifying that:

  1. The file is not compressed by default.
  2. The Content-Type is set based on the file format.

These changes improve the clarity of the documentation and should help users better understand the behavior of the SendFile method.

Consider adding a brief example of how to enable compression, as this might be useful for users who want to use this feature. For instance:

// To enable compression:
err := c.SendFile(file, SendFile{Compress: true})

Line range hint 1-479: Overall assessment: Documentation improvements

The changes in this file are focused on improving the clarity and consistency of the documentation, specifically addressing the usage of hyphens and grammatical correctness. These modifications align well with the PR objectives of enhancing documentation quality.

No functional changes were made to the code, ensuring that the existing behavior remains unchanged. The improvements contribute to better readability and understanding of the Route struct and the register method.

ctx_interface_gen.go (1)

274-275: Excellent documentation improvements for SendFile method!

The changes to the SendFile method documentation are clear and beneficial:

  1. The addition of information about file compression default behavior and how to enable it provides valuable guidance to users.
  2. The clarification about the Content-Type header being set based on the file format rather than just the file extension is more accurate and informative.

These updates align well with the PR objectives and enhance the overall quality of the documentation.

docs/api/ctx.md (2)

Line range hint 1712-1750: LGTM! Documentation improvements for SendFile config.

The updates to the SendFile configuration struct documentation are clear and informative. The clarifications on default values for various fields (Compress, ByteRange, Download, CacheDuration, MaxAge) and the explanation of the Content-Type behavior enhance the overall understanding of the SendFile method.


Line range hint 1764-1814: LGTM! Helpful example added for SendFile usage.

The new example demonstrating how to disable compression when using SendFile is a valuable addition. It clearly shows how to use the SendFile configuration struct to customize the method's behavior.
