javascript - Mongoose .find with a req.params array? and res.json an array of each value and count? -

-

ideally user able enter multiple tags in search field, delinienated client-side (before .get call), sent on ajax each keypress.

working on server-side (testing api postman), if .get serves variable tags array of [ 'tag1', 'tag2'], can req.params.tags array?

if so, server - right now, getting response postman localhost:4200/api/v1/tag/tagname .. not /tag/tagname1+tagname2 or /tag/tagname1&tagname2

here's current api:

router.route('/tag/:tags')      // list of tags usergenerated tags (accessed @ http://localhost:4200/api/v1/tag/:tags)     .get(function(req, res) {          story.count( { tags: { $in: [  req.params.tags ] } }, function (err, count) {              if (err)                 res.send(err);              console.log('there is/are %d story/ies this/these tag(s)', count);              if (count >= 1) {                  story.find( { tags: { $in: [  req.params.tags ] } }, 'tags', function(err, stories) {                      if (err)                         res.send(err);                      res.json(stories); // return count of each tag tag                  }); // find , return tags              } // if count >= 1              if (count < 1) {                  res.json({ message: count + ' results' });              } // if count < 1           }); // .count      }); // list of tags

secondly, need use .aggregate (have yet explore really) res.json array of tags can loop on each tagname , count each specific tag.

this isn't mongo-specific question, it's express question (i'm assuming using express here).

there isn't way express automatically parse dynamic segment (the part prefixed : in url) array, can yourself:

// example url: /tags/tag1,tag2 app.get('/tags/:tags', function(req, res){   var tags = req.params.tags.split(','); // ['tag1','tag2']   res.send('you entered tags :' + tags.join(',')); });
