Adding impurity in document.tsx code

[NirajC-Microsoft]

Purpose

This pull request makes several updates to the Document component in src/frontend/src/pages/document/Document.tsx to improve type safety, ensure proper handling of parameters, and adjust the user interface for better consistency. Below are the key changes:

Type Safety Improvements:

• Updated the getDocument function to parse the response as JSON and type it as DocumentData for better type safety. ([src/frontend/src/pages/document/Document.tsxL22-R23](https://github.com/NirajC-Microsoft/auto-pr-review-document-generation-solution-accelerator/pull/4/files#diff-9bf45c4b5ab23c2d2fa8fa9d2cfcc723789d8b91662ea9085f839df364b64ba3L22-R23))

Parameter Handling:

• Modified the getDocument call to explicitly cast params.id as a string, ensuring the correct type is passed. ([src/frontend/src/pages/document/Document.tsxL33-R33](https://github.com/NirajC-Microsoft/auto-pr-review-document-generation-solution-accelerator/pull/4/files#diff-9bf45c4b5ab23c2d2fa8fa9d2cfcc723789d8b91662ea9085f839df364b64ba3L33-R33))

UI Adjustments:

• Changed the fallback message for a missing document from an <h1> element to a <p> element for consistency with the rest of the UI. ([src/frontend/src/pages/document/Document.tsxL44-R44](https://github.com/NirajC-Microsoft/auto-pr-review-document-generation-solution-accelerator/pull/4/files#diff-9bf45c4b5ab23c2d2fa8fa9d2cfcc723789d8b91662ea9085f839df364b64ba3L44-R44))

Type Safety Improvements:

• Updated the getDocument function to parse the API response as DocumentData and ensure type safety when setting the document state. ([src/frontend/src/pages/document/Document.tsxL22-R23](https://github.com/NirajC-Microsoft/auto-pr-review-document-generation-solution-accelerator/pull/4/files#diff-9bf45c4b5ab23c2d2fa8fa9d2cfcc723789d8b91662ea9085f839df364b64ba3L22-R23))

Parameter Handling:

• Explicitly cast params.id to a string when calling getDocument to ensure proper type handling. ([src/frontend/src/pages/document/Document.tsxL33-R33](https://github.com/NirajC-Microsoft/auto-pr-review-document-generation-solution-accelerator/pull/4/files#diff-9bf45c4b5ab23c2d2fa8fa9d2cfcc723789d8b91662ea9085f839df364b64ba3L33-R33))

UI Consistency:

• Changed the "Document not found" message from an <h1> to a <p> tag for consistent styling with the rest of the component. ([src/frontend/src/pages/document/Document.tsxL44-R44](https://github.com/NirajC-Microsoft/auto-pr-review-document-generation-solution-accelerator/pull/4/files#diff-9bf45c4b5ab23c2d2fa8fa9d2cfcc723789d8b91662ea9085f839df364b64ba3L44-R44))

Data fetching and type handling:

• Changed the documentRead response processing from response.json() to response.text() and cast the result to any before setting the document state. This likely addresses a change in the expected response format.
• Updated the getDocument function call to explicitly cast params.id to string, ensuring type safety.

UI adjustments:

• Updated the fallback message for when a document is not found, replacing the <h1> tag with a <p> tag for better semantic alignment and consistency with the rest of the component.

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.

What to Check

Verify that the following are valid

• I have built and tested the code locally and in a deployed app
• For frontend changes, I have pulled the latest code from main, built the frontend, and committed all static files.
• This is a change for all users of this app. No code or asset is specific to my use case or my organization.

Pull Request Overview

This PR enhances the Document component by tightening type safety on the API response, ensuring consistent handling of the route parameter, and aligning the "not found" UI message with the component’s styling.

• Added explicit DocumentData typing when parsing the API response.
• Cast params.id to string to satisfy the getDocument signature.
• Changed fallback heading from an <h1> to a <p> for consistent UI.

Comments suppressed due to low confidence (2)

src/frontend/src/pages/document/Document.tsx:22

• [nitpick] The variable name data is generic; consider renaming it to fetchedDocument or documentData to clarify its role.

const data: DocumentData = await response.json(); // Parse response as JSON

src/frontend/src/pages/document/Document.tsx:23

• Add unit or integration tests covering the successful fetch path and the fallback when setDocument(null) is triggered to ensure both scenarios are validated.

setDocument(data); // Use the parsed and typed data

[Copilot]

Before calling response.json(), check response.ok and handle non-2xx statuses explicitly to avoid parsing errors on a failed request.

Suggested change

	const response = await documentRead(id);
	const response = await documentRead(id);
	if (!response.ok) {
	throw new Error(`Failed to fetch document: ${response.status} ${response.statusText}`);
	}

[Copilot]

Instead of casting params.id with as string, you can type your route params when calling useParams<{ id: string }>() to avoid manual casting.

Suggested change

	getDocument(params.id as string); //
	getDocument(params.id); //
