AWS Code Pipeline / Code Build / Lambda Configuration

Need to develop a code pipeline workflow that can combine builds from two different repositories into a single build artifact to be deployed to Elastic Beanstalk. See attached image for workflow that is desired. Frontend application is angular (source is in client) -> builds into a folder called "client/dist" Backend application is nodejs (source is in server) -> builds into a folder called "server/dist" "client/dist" folder contents is copied into the "server/dist/client" folder to complete the full build and then the contents of server/dist folder is deployed to elastic beanstalk. The shell execution for this looks like this. I already have the yaml for each separate build, the issue is with combining the two builds into a single deployment. cd client echo "<<<<<<<<<<<<<<<<<<<<<<<<PULL CLIENT>>>>>>>>>>>>>>>>>>>>>>" echo "<<<<<<<<<<<<<<<<<<<<<<<<NPM INSTALL>>>>>>>>>>>>>>>>>>>>>>" npm install echo "<<<<<<<<<<<<<<<<<<<<<<<<BUILD>>>>>>>>>>>>>>>>>>>>>>" node --max_old_space_size=8000 ./node_modules/.bin/ng build --prod --aot --verbose cd ../server echo "<<<<<<<<<<<<<<<<<<<<<<<<NPM INSTALL>>>>>>>>>>>>>>>>>>>>>>" npm install echo "<<<<<<<<<<<<<<<<<<<<<<<<BUILD>>>>>>>>>>>>>>>>>>>>>>" gulp build mkdir dist/client echo "<<<<<<<<<<<<<<<<<<<<<<<<COPY>>>>>>>>>>>>>>>>>>>>>>" cp -rf ../client/dist/* dist/client/
