this is an experamintal project for golang, serving a wrapper project over primes sieve algorithm.
Create a web application that takes in a number and returns to the user the highest prime number lower than the input number. For example, an input of 55 would return 53. Treat this like a real production application that you would be proud of.
technologies to be used:
- golang/gogin base server [√]
- typescript/react-jsx client side [√]
- sass styles [√]
- docker one config, one container [√]
- workbox offline caching, PWA [√]

Sieve of Eratosthenes allows us to generate a list of primes. with preformance of O(n x n)

go modules we will be using for this project
go gin framework
go-assets-builder
we will need to manually invoke this file everytime we add a file to the assets folder, we can automate this by using file watcher
commane line and usage:
generate assets
cd ./src
go-assets-builder views -o assets.go
run the app from src
cd ./src
go run .
build the app from src
cd ./src
go get github.com/GeertJohan/go.rice
go get github.com/GeertJohan/go.rice/rice
rice embed-go -i .
go build . -o ../build
run tests
cd ./src
go test .
install clientside dependenceis
yarn install or npm install note: please dont use both while installing, to avoid dependencies conflict
watch files changes and build assets development only
yarn start
build assets
yarn build
generate workbox caching sw
workbox generateSW
docker build
docker build . -t go-primes-sieve
run from docker image
docker run -i -t -p 8080:8080 go-primes-sieve
