Opportunity IQ is built on KeystoneJS which runs on Node & Express, and uses MongoDB for storage. The templating language is Jade.
/routes/views/register.js is where the registration / pricing logic is run.
/routes/views/register_success.js determines whether or not to redirect the user to the registration success page or to an analysis that they have already begun.
/routes/views/analysis.js is the home page of the app, where the user either creates a new assessment or continues on an existing one.
/routes/views/index.js is the actual assessment.
/routes/views/printable.js is where the logic for rendering the printout is contained.
/routes/views/password/forgotPass.js is the password reset form, where the user requests a reset email.
/routes/views/password/resetPass.js is where the user enters a new password and the users token is checked for authenticity.
/models/users.js has the resetPassword method which is where the reset token is generated and stored to the users account.
/templates/emails/forgotten-password.js is the template for the email sent out to the user that requested a password reset token.
Assessments are stored in a few seperated models. analysis.js is the main assessment model. This stores two primary fields, "user", and "title", as well as the database "_id". Using these fields we load the related records for each answer (answer.js). Each record in pages.js is a question in the assessment flow.
