In this third installment of building Touchbase, I will go in depth about creating an email verification system using Couchbase, nodemailer, and the Sendgrid Web API. The first thing you will need to do is download a couple of node modules.<\/p>\n
The first two installments, Part 0<\/a> and Part 1<\/a>, cover the data model and user document creation, respectively.<\/p>\n <\/p>\n First, to bring in the node modules, do:<\/p>\n Then:<\/p>\n If you’re not familiar with Node, npm simply installs modules for you. The ‘–save’<\/strong> ending will add these modules to your package.json<\/strong> file. From the Touchbase github repo, you will see that these are already in the package.json<\/strong> file.<\/p>\n First, create a Sendgrid account to use their free web API<\/a>. I will assume you have this, and continue on. After that, you will need to do some simple setup of the Sendgrid API to actually send emails using Sendgrid and nodemailer. The explanation of using these two services together is in Sendgrid’s blog<\/a> and I will go further using that code snippet. My usage of this in the models\/sessionmodel.js<\/strong> file in a function called ‘Session.makeVerification’<\/strong>. The endpoint where this function is called can be found in routes\/routes.js<\/strong> as ‘\/api\/registerUser’<\/strong>, which I talked about at length in my last blog<\/a>. This function is called at the end of that route to generate a verification email, which the user must click before logging into their account, to avoid abuse of the service.<\/p>\n In the models\/usermodel.js<\/strong> file, the ‘User.create’<\/strong> function has a boolean field in the sub-object ‘login’ called ’emailVerified’. The importance of this, is that our verification route will change this attribute of the user to true, allowing them to login if their email has been verified.<\/p>\nPlatform Requirements<\/h4>\n
