find-one-record

Express middleware factory for finding one record with Sequelize and attaching it as an attribute of req, or returning 404 if not found.

Installation

npm install @ryanburnette/find-one-record

Usage

Use it in an Express + Sequelize app.

var findOneRecordMiddlewareFactory = require('@ryanburnette/find-one-record');
var findOneWidget = findOneRecordMiddlewareFactory({
  pkName: 'id',
  model: db.Widget
});
app.get('/api/widgets/:id', findOneWidget, function (req, res) {
  res.json(req.record);
});

Behavior

The primary key is expected to be req.body[pkName]. If a record isn't found a 404 is returned and the middleware chain is broken. The found record is req.record.

Options

pkName primary key attribute name, defaults to id
model required, pass in the Sequelize model
