OneKey Coding Patterns and Best Practices

Quick Reference

Topic	Guide	Key Points
Promise handling	promise-handling.md	Always await or use void, never floating promises
React components	react-components.md	Named imports, functional components, no FC type
Restricted patterns	restricted-patterns.md	Forbidden: toLocaleLowerCase, direct hd-core import

Critical Rules Summary

Promise Handling

// ❌ FORBIDDEN - floating promise
apiCall();

// ✅ CORRECT
await apiCall();
// or
void apiCall(); // intentionally not awaited

React Components

// ❌ FORBIDDEN
import React, { FC } from 'react';
const MyComponent: FC<Props> = () => {};

// ✅ CORRECT
import { useState, useCallback } from 'react';
function MyComponent({ prop }: { prop: string }) {}

Restricted Patterns

// ❌ FORBIDDEN
string.toLocaleLowerCase()
import { x } from '@onekeyfe/hd-core';
import { localDbInstance } from '...';

// ✅ CORRECT
string.toLowerCase()
const { x } = await CoreSDKLoader();
import { localDb } from '...';
