Release Status Flow - Web Replay Lab

A small release dashboard builds its HTML shell, reads URL state, applies CSS-facing DOM state, and renders API data into the page.

Program

The flow starts with a stable app mount. JavaScript creates the page structure, reads the target environment from URL state, then writes API status into DOM attributes, classes, text, and list items.

release_status_flow.js

const app = document.querySelector('#release-app');
const params = new URLSearchParams('?env=prod');
const apiResult = { status: 'ready', version: '2.4.0', checks: ['HTML shell', 'CSS state', 'DOM sync'] };

app.innerHTML = `
  <header class="release-head">
    <h2>Release desk</h2>
    <span id="env-label">Environment pending</span>
  </header>
  <section id="release-card" class="release-card" data-status="loading">
    <strong id="version">Waiting for API</strong>
    <ul id="checks"></ul>
  </section>`;

const env = params.get('env') || 'staging';
const card = app.querySelector('#release-card');
const envLabel = app.querySelector('#env-label');
const version = app.querySelector('#version');
const checks = app.querySelector('#checks');

app.dataset.env = env;
envLabel.textContent = `Target: ${env}`;

card.dataset.status = apiResult.status;
card.classList.add('ready');
version.textContent = `Version ${apiResult.version} ${apiResult.status}`;

checks.innerHTML = apiResult.checks
  .map(check => `<li>${check}</li>`)
  .join('');

integration flow An integration flow connects browser state, data, DOM updates, and CSS selectors in one path.

data-driven styling Data attributes and classes let CSS respond to JavaScript state without rebuilding the whole page.

API payload An API payload is external data. Client code turns it into visible UI state.
