Graphql server to get stock values

This is a demo project about how to get stock quotes using a web crawler with Go.

Clone

git clone [e-mail]:boniattirodrigo/stock.git

Run

Make sure that you're using the right Go version defined on .tool-versions.

You need to set a Postgres database url, copying and changing the .env file:

cp .env-sample .env

Create the database that you defined on the database url.

Spin it up with:

go run main.go

  stocks(tickers:["PETR4", "LREN3", "AZUL4"]) {

  stocks(tickers:["PETR4", "LREN3", "AZUL4"]) {
