express-sequelize-sort

Parse req.query.sort to res.locals.sort

Installation

npm install --save express-sequelize-sort

Usage

Mount the middleware in your router.

app.get('/api/items', require('express-sequelize-sort'), ctrl);

If there is a req.query.sort value, the middleware will convert it to something sequelize understands.

'?sort=-name,number'            => [['name', 'DESC'], ['number', 'ASC']]
'?sort[0]=-name&sort[1]=number' => [['name', 'DESC'], ['number', 'ASC']]
'?sort[name]=-1&sort[number]=1' => [['name', 'DESC'], ['number', 'ASC']]

NOTE: This module does not validate the actual sort properties. You might want to pick only the ones you know are valid for that specific route instead of passing directly to sequelize.

const ALLOWABLE_SORT_PROPS = ['name', 'number'];

function ctrl(req, res, next) {
  const sort = res.locals.sort.filter(order => (ALLOWABLE_SORT_PROPS.indexOf(order[0]) !== -1));
  // ...
}
