how do I import json generated by javascript into Mongodb -

-

i need rid of newline character separates objects in json file can import mongodb without having objects in array. use in javascript this? need data in format can import:

{ name: "widget 1", desc: "this widget 1" }
{ name: "widget 2", desc: "this widget 2" }

the answer is, dont have convert file array, mongoimport expects "json-line" format have.

this format performance, because don't have load @ once, instead mongo take line line. imagine billion lines, if convert array, cost memory...

this way linear time operation, lines gets streamed db.

look here:

however, if think need conversion, this:

fs.readfile('my.json', function(e, text) {    var arraylikestring = "[" + text.split('\n').join(',') + "]";    var array = json.parse(arraylikestring); })

to import array of objects use command:

mongoimport --db <db-name> --collection <coll-name> --type json --jsonarray --file seed.json

note option: --jsonarray

finally:

take @ npm package, looks promisingly:

https://www.npmjs.com/package/jsonlines

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
