Implements Google Cloud Proxy by default

This reduces hassle for developer to update IP in Cloud SQL during IP Change.

Implemented through docker image as follows

• Cloud SQL -> Google Proxy Docker Image -> Web App

Points to remember for smooth working

• ServiceAccountKey.json requires Cloud SQL Read and Write Permission
• DB_HOST_NAME value in .env is required
• DB_HOST=cloud-sql-proxy instead of IPV4 or DB_HOST_NAME for development environment
• DB_PORT will be 3306 by default

For auto generate of CRUD(Create, ReaD, Update & Delete) api following informations are needed and will be asked in terminal:

• resource-name: name of CRUD in upper camelCase. examples:Food,Puppy,ProductCategory etc.

• resource-table-name: name of CRUD in lower snake case. examples:food,puppy,product_category etc.

• plural-resource-table-name: plural name for the table going to be created. example: foods, puppies, product_categories.

• plural-resource-name: plural name of CRUD in Upper camelCase. examples:Foods,Puppies,ProductCategories etc.
