About X-Total-Count about json-server HOT 6 CLOSED

Hi @typicode
we can enable this (a count property in the body response) via a flag?
Several (request) solution doesn't provide a way to access to header data.

from json-server.

I found a solution by creating server.js :

Const jsonServer = require('json-server')
.....
....
....

router.render = function(req, res) {
Var newData = {
TotalCount: res.get('X-Total-Count'),
Result: res.locals.data
}
res.json(newData)
}

@lowdev, Thank you, This should be the accepted answer.

I was searching for how to get X-Total-Count from render, your answer inspired me. Here is some slightly formatted code.

router.render = (req, res) => {
  // if it's a GET request and result is an Array
  if (req.method === 'GET' && Array.isArray(res.locals.data)) {
    res.json({
      total: res.get('X-Total-Count'),
      list: res.locals.data,
    })
  }
}

There's many way to return a slice of an array, and you're right that's a valid way to do.
There was also a discussion about pagination here: #57

For the moment, I prefer to return an array and meta in headers. But maybe a mock server implementing JSON API would work better with ExtJS (never used this lib)... can't remember right now other mock server names, but there is fortunejs.

Sorry about that.

Is there any solution to do that?

With your solution, you'll not have the "total count", but the number of returned items.

I found a solution using lowdb. It's not perfect because we need to call the db twice (one for the initial request, one for the total count).

For example, I want to count the number of users.

const db = await low(myStorage);

const countItems = resource =>
  db
    .get(resource)
    .map('id')
    .value().length;

router.render = (req, res) => {
  res.jsonp({
    items: res.locals.data.items,
    totalItems: countItems('users') // parse url to get the desired resource
  });
};
