Example GraphQL API implemented in Go and backed by Postgresql

How to run it

To run this project you need to: - install golang, see this guide - install Masterminds/glide which is a package manager for golang projects. - install all the dependencies for this project:

glide install
, glide will store all dependencies in
/vendor
folder. - install postgresql (for ubuntu follow this guide). For this application, I created a postgresql user called
vagrant
with
vagrant
as password and the database called
graphql
, but of course you can change these settings in
./migrate.sh
and in
./main.go
files. - install mattes/migrate which is a tool to create and run migrations against sql databases. - run the migrations which will create the database tables and indexes
./migrate.sh up
. If you ever want to clean up the the database run
./migrate.sh down
then
./migrate.sh up
again.
