Tencent WeDa developer learning path

1. dynamic approval routing (amount ≥ 50,000 plus CFO)

// 事件：表单提交前
const amount = Number($w.amountInput.value || 0);
const dept = await app.cloud.callFunction({
  name: 'getManager',
  data: { userId: app.dataSources.user.openid, level: 1 }
});
let approvers = [dept.data, 'finance_head_id'];
if (amount >= 50000) approvers.push('cfo_id');
return { approverIds: approvers.filter(Boolean) };

2. calls a custom connector to query ERP

// 事件：页面加载
const res = await app.dataSources.ErpCustomer.wedaGetRecords({
  filter: {
    where: { region: { $eq: '华东' } }
  },
  pageSize: 50
});
$w.customerTable.setData(res.records);
// 错误兜底
if (!res.records?.length) app.utils.toast('无数据');

🧪 Development/Testing/Production

Use WeDa multi-environment isolation, and configure variables to point to different databases and connectors to avoid production data pollution.

🧭 Version and Grayscale

Version snapshots and rollbacks are supported. Key changes are grayscaled to 10% users first, and error rates are monitored before full rollout.

📦 Export with Git

The application can export zip structured files and cooperate with Git for version management, code review and branch merging.

📊 Monitoring & Alerting

Cloud function log → CLS; operating indicators → cloud monitoring; when the error rate/delay exceeds the threshold, the enterprise micro notification is on duty.

🔐 Key management

Third-party keys are stored in "environment variables" or Tencent Cloud SSM parameter warehouse, and hard coding into code blocks is strictly prohibited.

🧱 Component library management

The enterprise private component library is released in versions and can be referenced by semver in the application. Downgrades can be rolled back with one click.
