Node.js Lambda - Using TypeORM with MySql -


i'm trying build lambda's in node.js , using typeorm mysql. have installed required node modules when deploy lambda (via serverless) , test it, errors follows. using gulp build , package .zip.

log output test lambda:

my research has led me believe won't package correctly because native module. i'm not sure. if there anyway native node modules work lambda's?? appreciated, thanks.

edit

folder structure:

deploy -- dev ---- serverless.yml ---- project.zip -- test ---- serverless.yml ---- project.zip -- prod ---- serverless.yml ---- project.zip  node_modules -- * ---- *  src -- api ---- user ------ index.ts -- data ---- user.ts -- models ---- user.ts  gulpfile.js index.ts package.json tsconfig.json tslint.json

gulp file calls function aws-lambda-typescript module has numerous gulp tasks.

const gulp = require('gulp'); const awslambdatypescript = require('aws-lambda-typescript');  awslambdatypescript.registerbuildgulptasks(gulp, __dirname);

gulp packages .zip in dist folder , copy deploy>dev , serverless deploy.

thanks help!

most wrong packaging process. i'd check following items:

  1. check package.json if mysql there.
  2. check zip file inside .serverless directory see if includes node_modules.
  3. download lambda package uploaded , again check if node_modules there.
