I tried json filter, but I get "json" filter not found error. What I'm I doing wrong?
Error: Filter "json" not found at Object.exports.wrapFilter (......./node_modules/swig/lib/helpers.js:310:11)
<script type="text/javascript">
{{ places|json }}
</script>
object is passed from mongodb
this.displayMainPage = function(req, res, next) {
"use strict";
places.getPlaces(10, function(err, results) {
"use strict";
if (err) return next(err);
return res.render('places_template', {
places: results
});
});
}
Edit: I'm trying to output json to pass to google maps and display the same data in html

To load the data from customer. json file, we will use fs. readFile , passing it the path to our file, an optional encoding type, and a callback to receive the file data. If the file is successfully read, the contents will be passed to the callback.
nodejs-write-json-object-to-file.jsparse(jsonData); console. log(jsonObj); // stringify JSON Object var jsonContent = JSON. stringify(jsonObj); console. log(jsonContent); fs.
Swig is an awesome, Django/Jinja-like template engine for node. js.
For versions of Swig prior to 1.0, the json filter was instead named json_encode:
{{ places|json_encode }}
And, for compatibility, 1.0 and later keep json_encode as an alias of json.
Though, you should also consider upgrading Swig:
$ npm install [email protected]
npm WARN deprecated [email protected]: v1.0.0 is a complete rewrite of Swig
from the ground up. Previous versions are no longer supported
