Running nodejs code in lambda is same as running same code on any other server or your local machine.在 lambda 中运行 nodejs 代码与在任何其他服务器或本地机器上运行相同的代码相同。 You get the same nodejs runtime.
您将获得相同的 nodejs 运行时。 There might be limitations when it comes to lambda such as package size, but there is no difference in how the code is executed.
对于 lambda,可能存在一些限制,例如包大小,但代码的执行方式没有区别。

I'm posting a complete lambda function that works with the SQL database.我正在发布一个与 SQL 数据库一起使用的完整 lambda 函数。
const sql = require('mssql');
const config = {
user: "username",
password: "password",
server: "server",
database: "database name",
options: {
//In case of azure database
encrypt: true
}
}
exports.handler = async event =>
{
if(event.httpMethod ==='GET')
{
return await getRecord(event);
}
};
const getRecord = async event =>
{
try
{
// Open DB Connection
let pool = await sql.connect(config)
// Query Database
let result = await pool.request().query('select * from tablename')
// Close DB Connection
pool.close();
// The results of our query
console.log("Results:", result);
return
{
statusCode:200,
body:result
}
}
catch (err)
{
// Error running our SQL Query
console.error("ERROR: Exception thrown running SQL", err);
}
}
