Prerequisite

Install Node JS and NPM.

Download

You can download using git:

git clone https://github.com/miftahul-huda/gcsfileuploader.git

Install

Go to "component-rating-backend" folder. Run:

npm install

Configuration

This uses port 8080 to connect and PostgreSQL. To configure the PostgreSQL connection in App Engine, create app.yaml file with this code:

service:  gcsfileuploader-v2
runtime:  nodejs12
env:  standard
env_variables:
    PORT:  "8080"
    DBHOST:  "<IP ADDRESS>"
    DBNAME:  "gcsfileuploader"
    DBUSER:  "<dbuser>"
    DBPASSWORD:  "<dbpassword>"
vpc_access_connector:
    name:  projects/<project-id>/locations/<region-id>/connectors/<vpc-access-connector-name>

This app uses Cloud SQL with private IP connection in GCP. So you'll need to create Serverless VPC Access connector first. vpc-access-connector-name is the Serverless VPC Access connector name you created.

Run Locally

To run locally, just type in the console in the root folder of this application:

PORT=8080 DBHOST=<dbhost> DBNAME=<dbname> DBUSER=<dbuser> DBPASSWORD=<dbpassword> node app.js

Deploy in App Engine

To deploy to App Engine first you have to login first to GCP using command:

gcloud auth login

Make sure you logged in using username who can access the GCP environment. After login, deploy the application in app engine:

gcloud app deploy

Once done, open the link that displayed in the output of the deploy command.
