How emerisscala/playlove-core works
Purpose and Runtime
This is an Express/Node.js server with EJS-rendered views and Sequelize-managed relational persistence. It appears to model a content/community and assessment domain: users, publications, lists/items, forum questions/answers/comments, reactions/reports, topics, tests, and user test results.
Primary startup paths are app.js, which configures the Express application, and bin/www, which runs the HTTP server.
HTTP Application Boundary
app.js is the composition root for middleware, static assets, view rendering, routing, and error handling. EJS templates are served from views/, while browser-accessible assets are exposed from public/.
Route entry points are currently limited to:
• routes/index.js
• routes/users.js
These routes are mounted by app.js; they form the request-to-render/controller boundary.
Server-rendered Presentation
The application uses EJS rather than a separate frontend runtime. Initial page and error rendering are represented by:
• views/index.ejs
• views/error.ejs
• public/stylesheets/style.css
This indicates a conventional server-rendered Express flow: HTTP request → route handler → EJS view or error response.
Persistence Layer
Sequelize is the ORM and schema lifecycle mechanism. Connection/environment settings are expected in:
• config/config.json
• .sequelizerc
• database/models/index.js
database/models/index.js is the likely model registry and association assembly point; application code should consume models through it rather than independently constructing ORM connections.
Core Domain: Identity and Content
User identity is the base entity, with publication and list/item content structures:
• database/models/User.js
• database/models/Publication.js
• database/models/List.js
• database/models/Item.js
Corresponding migrations establish the persisted schema, including database/migrations/20190621164830-create-user.js and the publication/list/item migration sequence. This domain likely supports user-authored or user-associated content.
Core Domain: Community Interaction
Forum and moderation/reaction entities define a discussion workflow:
• database/models/Topics.js
• database/models/Forum_Question.js
• database/models/Answer.js
• database/models/Comment.js
• database/models/Kiss.js
• database/models/Report.js
The implied control flow is topic/question creation → answers/comments → positive reaction (“Kiss”) or report/moderation action. Relationship cardinality and ownership should be verified in the model association definitions before extending this flow.
Core Domain: Assessment
Assessment is modeled separately from general discussion:
• database/models/Test.js
• database/models/Test_Question.js
• database/models/Key.js
• database/models/User_Test.js
The expected data flow is test definition → test questions and answer keys → a user test/attempt record. User_Test is the important join/state boundary between User and Test.
Schema Evolution and External Dependencies
Database schema is versioned through database/migrations/; seed data begins with database/seeders/20190708051105-user.js. Sequelize CLI configuration is rooted at .sequelizerc.
Material infrastructure is therefore Node.js/Express, EJS, Sequelize, and a SQL database selected by config/config.json. No external API, queue, cache, authentication provider, or deployment service is evidenced by the supplied repository tree.
