本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- When the `query parser` setting is left unset on an Express application, Express defaults `app.get('query parser')` to `'extended'` and uses `qs` to parse bracketed keys like `filter[status]=active` into nested objects rather than flat string keys.
- assert.strictEqual(app.get('query parser'), 'extended')
- assert.strictEqual(app.get('etag'), 'weak')
- assert.strictEqual(app.get('subdomain offset'), 2)
- assert.strictEqual(app.get('x-powered-by'), true)
- assert.strictEqual(app.get('trust proxy'), false)
- assert.deepStrictEqual(req.query, { filter: { status: 'active', limit: '10' }, tags: ['backend', 'express'] })
- assert(res.headers['etag'].startsWith('W/"'))
- assert.strictEqual(res.headers['x-powered-by'], 'Express')
- assert.deepStrictEqual(req.subdomains, ['v1', 'api'])
- assert.deepStrictEqual(req.ips, [])
