is there a require for json in node js

Question

I would like to include a couple of JSON files in my JavaScript code that are in the same directory as my JavaScript source file   If I wanted to include another JavaScript file I could simply use require  Now I m using readFileSync and   dirname to get the JSON  which I think is an ugly way to do it   Is there something similar for require that enables me to load a JSON file

You even can use require of your JSON without specifying the extension  json  It will let you change the file extension to  js without any changes in your imports   assuming we have   myJsonFile json in the same directory   const data   require    myJsonFile     If in the future you ll change   myJsonFile json to   myJsonFile js nothing should be changed in the import

No  Either use readFile or readFileSync  The latter only at startup time    Or use an existing library like   cjson   Alternatively write your config in a js file rather then a json file like  module exports          json

You can import json files by using the node js v14 experimental json modules flag  More details here file js import data from    folder file json   export default     foo          console log data         And you call it with node --experimental-json-modules file js

JSON files don   t require an explicit exports statement  You don t need to export to use it as Javascript files    So  you can use just require for valid JSON document   data json       name    Freddie Mercury      main js  var obj   require  data json     console log obj name      Freddie Mercury

Two of the most common  First way    let jsonData   require    JsonFile json     let jsonData   require    JsonFile      if we omitting  json also works  OR   import jsonData from     JsonFile json     Second way    1  synchronously  const fs   require  fs   let jsonData   JSON parse fs readFileSync  JsonFile json    utf-8      2  asynchronously   const fs   require  fs   let jsonData      fs readFile  JsonFile json    utf-8    err  data    gt      if  err  throw err    jsonData   JSON parse data       Note   1  if we JsonFile json is changed  we not get the new data  even if we re run require    JsonFile json    2  The fs readFile or fs readFileSync will always re read the file  and get changes
