certifier-go

A web application developed in Go to create and send bulk certificates.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites & Installing

• Go 1.10.3 or later (https://golang.org/dl/);
• wkhtmltopdf 0.12.5 or later (https://wkhtmltopdf.org/downloads.html);
• Git 2.18.0 or later (https://git-scm.com/downloads);
• Go libraries

Note: Verify that your GOPATH is set and that the wkhtmltopdf installation was successful through the following commands:

go env
wkhtmltopdf -V

Note: On Windows, you will need to set the wkhtmltopdf PATH. To learn how to set, go to this link.

After installing the previous ones, obtain the following libraries:

• go-wkhtmltopdf: Golang commandline wrapper for wkhtmltopdf

go get -u github.com/SebastiaanKlippert/go-wkhtmltopdf

• sendgrid-go: The Official SendGrid Led, Community Driven Golang API Library

go get -u github.com/sendgrid/sendgrid-go

Finally, obtain this project through the following command:

go get -u github.com/silvnt/certifier-go

Running

Linux

Before executing, open the command line in project folder ($GOPATH/src/github.com/silvnt/certifier-go), enter the values of SENDGRID_API_KEY and SERVER_ADDRESS (if the latter is empty, the default is 'localhost:3000') in local.env, and run the following command:

source local.env

Note: You don't have to run this command again until you open a new terminal instance.

Now, start the service:

go run certifier.go

Windows

On Windows, you will need to set environment variables manually (SENDGRID_API_KEY and SERVER_ADDRESS). To learn how to set environment variables in Windows, go to this link.

After this, start the service:

go run certifier.go
