PROJECT 081

TypeScript Project: Semantic Repair Station

Concept

One DOM transformation pipeline can safely improve several accessibility patterns together.

Concept

One DOM transformation pipeline can safely improve several accessibility patterns together.

Objective & Explanation

What the project should make visible and why the concept matters.

Learning Target

Objective

Apply all supported semantic repairs to pasted HTML.

Explanation

One DOM transformation pipeline can safely improve several accessibility patterns together.

Project Plan

Structure, technologies, data boundary, and source connection.

Structure

Technologies

TypeScript
DOM

Data Layer

No persistent data layer. Keep all demonstration values inside the standalone project.

Sandbox Source

src/local-editor/client.ts → semanticAssistHtml()

Build Instructions

Build only the focused behavior, then use the visual layer to inspect it.

Setup

Create the standalone project folder and listed files.

Implement

Implement the smallest version that demonstrates the concept.

Run & Inspect

Change one input and observe the visible output change.

Code & Configuration

Starter configuration plus the focused implementation example.

Focused TypeScript

Implement this behavior first, then alter the input.

const template = document.createElement("template");
template.innerHTML = inputHtml;

repairImages(template.content);
repairButtons(template.content);
repairLinks(template.content);
repairTables(template.content);

output.value = template.innerHTML;

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: apply all supported semantic repairs to pasted HTML.
