const { Client } = require('@elastic/elasticsearch')
const client = new Client({
cloud: { id: '<cloud-id>' },
auth: { apiKey: 'base64EncodedKey' },
maxRetries: 5,
requestTimeout: 60000,
sniffOnStart: true
})

要使用的 Elasticsearch 端点。 node: 'https://127.0.0.1:9200' 或者它可以是一个对象（或对象数组），表示节点 node: {
url: new URL('https://127.0.0.1:9200'),
tls: 'tls options',
agent: 'http agent options',
id: 'custom node id',
headers: { 'custom': 'headers' }
roles: {
master: true,
data: true,
ingest: true,
ml: false
}
}

您的身份验证数据。您可以使用基本身份验证和 ApiKey。 基本身份验证 auth: {
username: 'elastic',
password: 'changeme'
}
ApiKey 身份验证 auth: {
apiKey: 'base64EncodedKey'
}
Bearer 身份验证，适用于 服务帐户令牌。请注意，它不处理自动令牌刷新 auth: {
bearer: 'token'
}
