ts-node inside AWS Lambda cannot resolve dependencies in /opt/nodejs/node_modules #1430
Description
Hi,
Using ts-node I'm trying to use Typescript directly inside lambda function on AWS, to do this I'm using this sample code:
require('ts-node/register');
console.log('Register!');
const { main } = require('./src/test.ts');
exports.handler = async function handler() {
console.log('Starting...');
await main();
console.log('Done!');
};The problem is that in my lambda the node_modules directory is placed in a layer /opt/nodejs/node_modules
So what happens is that ts-node doesn't find libraries on the imported sources giving errors such:
src/test.ts(2,21): error TS2307: Cannot find module '@aws-sdk/client-s3' or its corresponding type declarations.
I'm trying to override the configuration of ts-node using this code, but still no luck.
var tsNode = require('ts-node');
var service = tsNode.register({
lazy: true,
files: false,
compilerOptions: {
