在 AWS lambda 函数中使用 require

Question

I am currently researching AWS lambda functions and I can't find anywhere if I can use the require statement in them so that I can use other, non-lambda functions. I know about zipping the node modules folder but this doesn't help me here as I don't intend to use a node module, thanks for any answers!

Answer 1

Just to add to Justin's answer, yes you can require other files in lambda with this structure as an example:

| main.js << The handler is here
| func1.js
| func2.js

and in the main file:

// main.js
require('./func1.js');
require('./func2.js');

Answer 2

Yes, you can. You just have to ensure that the node_modules folder is uploaded as part of your package (you won't be able to use the console editor). You can read more details on the AWS Blog:

Using Packages and Native nodejs Modules in AWS Lambda

Answer 3

In addition to Naguib Ihab's answer. If you want to call function declared in the other JS files, you can declare that function in this way:

exports.handler = async () => {
  return "Hello world"
};

and in your invoking function:

const funA = require(path-to-file)

invoke the function by

funA.hanlder()

instead of

funA()
