TypeScript Lab: Icon Link Naming
Concept
Accessible naming can be added conditionally when visible link text is absent.
Concept
Accessible naming can be added conditionally when visible link text is absent.
Objective & Explanation
What the project should make visible and why the concept matters.Learning Target
Objective
Give icon-only links accessible names when reliable text exists.
Explanation
Accessible naming can be added conditionally when visible link text is absent.
Project Plan
Structure, technologies, data boundary, and source connection.Build Instructions
Build only the focused behavior, then use the visual layer to inspect it.Setup
Create the standalone project folder and listed files.Install TypeScript locally and initialize the compiler configuration.
Implement
Implement the smallest version that demonstrates the concept.- Implement only the concept shown in the code example.
- Compile the TypeScript and load the browser page.
Run & Inspect
Change one input and observe the visible output change.Change one input or action and confirm the visible result changes for the expected reason.
Code & Configuration
Starter configuration plus the focused implementation example.Focused TypeScript
Implement this behavior first, then alter the input.document.querySelectorAll("a[href]").forEach(link => {
const visible = link.textContent?.trim();
const title = link.getAttribute("title")?.trim();
if (!visible && title && !link.hasAttribute("aria-label")) {
link.setAttribute("aria-label", title);
}
});Starter Configuration
Keep the project independently buildable.package.json
{
"type": "module",
"scripts": { "build": "tsc" },
"devDependencies": { "typescript": "^7.0.2" }
}tsconfig.json
{
"compilerOptions": {
"rootDir": "./src",
"outDir": "./dist",
"target": "ES2022",
"module": "ES2022",
"lib": ["ES2022", "DOM"],
"strict": true,
"sourceMap": true
},
"include": ["src/**/*.ts"]
}Expected Visual Result
The output is the proof that the concept is working.Visible Proof
The browser should visibly demonstrate: give icon-only links accessible names when reliable text exists.
