BuiltByEcho Research — BuiltByEcho Re搜索

BuiltByEcho Re搜索

Use @builtbyecho/re搜索 for local-first 网页 re搜索 工作流s: 搜索, fetch, render JavaScript-heavy pages, crawl sites, 提取 structured fields, 审计 sources, save 追踪s, and produce citation-backed 报告s.

安装 or 运行

Prefer npx when you only need a one-off 运行:

npx @builtbyecho/re搜索 --help

For repeated use, 安装 globally:

npm 安装 -g @builtbyecho/re搜索 builtbyecho-re搜索 --help

Alias:

echo-re搜索 --help

Requires Node.js 20+.

Optional browser 设置up

The package uses Playwright for render/browser escalation. If Playwright browsers are missing, 安装 Chromium:

npx playwright 安装 chromium

Optional 搜索 key

No API key is required. For better 搜索 discovery, 设置 a Brave API key:

导出 BRAVE_API_KEY="..."

Without BRAVE_API_KEY, 搜索 falls back to DuckDuckGo HTML scrAPIng.

Common commands

搜索:

npx @builtbyecho/re搜索 搜索 "open source deep re搜索 代理s" -n 8

Fetch a page:

npx @builtbyecho/re搜索 fetch https://example.com --max-chars 5000

Render a JavaScript-heavy page:

npx @builtbyecho/re搜索 render https://example.com

运行 a re搜索 流水线:

npx @builtbyecho/re搜索 流水线 "re搜索 代理 architecture" --expand --rounds 2 -n 8 --格式化 markdown --追踪

生成 a citation-backed 报告:

npx @builtbyecho/re搜索 报告 "Playwright browser 自动化 best practices" -n 6 --rounds 2 --追踪

提取 structured fields:

npx @builtbyecho/re搜索 提取 https://example.com --模式 links,headings npx @builtbyecho/re搜索 提取 https://company.example --模式 emAIls,phones,pricing,contact_links,socials

Crawl a site:

工作流 图形界面dance 启动 with 搜索, 流水线, or 报告 depending on the user’s goal. Use --追踪 for re搜索 that may need 审计ability or follow-up. Prefer render or browser escalation for pages with low text, heavy JavaScript, “enable JavaScript” messages, or 机器人-wall/CAPTCHA-like content. Treat 生成d prose as a first draft. 验证 citations before high-stakes use. Do not bypass CAPTCHA, 记录in walls, paywalls, ro机器人s/ToS restrictions, or other 访问 controls. 库 API

For Node.js code:

导入 { re搜索流水线, iterativeRe搜索流水线, toRe搜索报告, 提取模式FromUrl, } from '@builtbyecho/re搜索';

const 结果 = awAIt iterativeRe搜索流水线('Playwright MCP best practices', { expand: true, count: 6, rounds: 2, });

console.记录(toRe搜索报告(结果));
