AI Code Review

This is an automated review generated by the code-reviewer agent.

Summary

The documentation is well-structured and accurately covers all requirements from issue #3. The code examples are syntactically correct and the MIME type table matches the server implementation. However, there are a few minor issues with incomplete documentation and a missing MIME type in the table.

Findings

Code Quality

Documentation structure: Clear, logical flow from basic setup to production considerations
Code examples: All examples are syntactically correct and follow Go conventions
Completeness: All four requirements from issue #3 are addressed (basic setup, static files, WASM MIME types, dev/prod)

Potential Bugs

host/README.md:39: The claim that / maps to public/index.html is slightly misleading. According to server.go:33-41, the root path / is cleaned and joined with publicDir, then checked with os.Stat. If it's a directory (which it would be for "/"), it falls back to index.html. This is correct behavior but the documentation could be clearer that root specifically triggers the directory fallback.

Documentation Accuracy

MIME type table incomplete: The README shows 6 MIME types (.wasm, .html, .js, .css, .json, .svg), but server.go:117-149 implements 15 types including .ico, .png, .jpg/.jpeg, .gif, .woff, .woff2, .ttf, .eot. While the table focuses on "common file types" relevant to WASM apps, it might be worth noting that additional types are supported.
Compression list missing text/plain: README lists compressible types but omits text/plain which is in server.go:104. This is a minor omission since plain text files are less common in WASM apps.
Development example inconsistency: Line 78 shows http.ListenAndServe(":8080", server) without error handling, while the basic setup (line 20) correctly uses log.Fatal. For consistency and best practices, the development example should also handle the error.

Style Notes

Documentation follows a clear progression from simple to complex
Code formatting is consistent with Go conventions
The nginx example is helpful and accurate

Test Coverage

No tests are included in this PR, but this is documentation-only so no test changes are expected
The test plan in the PR description covers the right verification steps

Recommendations

Minor improvements (not blocking):

Consider noting in the MIME types section that "additional common web asset types are also supported (fonts, images, etc.)"
Add text/plain to the compression list for completeness
Add error handling to the development example: log.Fatal(http.ListenAndServe(":8080", server))
Optionally clarify that / triggers the directory fallback behavior

Verdict

LGTM

This PR successfully addresses all requirements from issue #3. The documentation is accurate, well-organized, and provides practical examples for both development and production use. The minor documentation gaps mentioned above don't affect the core accuracy or usefulness of the guide.
