Trying to create utility functions, usually use python and getting used to node, this function won't export for some reason - says "SaveJson is not a function".
exports.mySaveJson = function(obj) {
var blob,file,fileSets,obj;
/**
* Creates a file in the local drive
*/
var date = new Date();
var fs = require('fs');
var n = date.toString();
var name = n.concat("_scraped_data.json");
// console.log(name)
fileSets = {
name: name,
mimeType: 'application/json'
};
blob = JSON.stringify(obj);
file = fs.writeFile(fileSets, blob, callback);
return file;
};
into
const SaveJson = require("./utilities.js")
....
SaveJson(ans)
Love some help just understanding what is wrong:)
I guess you should say SaveJson.mySaveJson(ans);
You are getting the module not the function. These are different things:
const {mySaveJson} = require('./utitities.js');
and
const SaveJson = require('./utitities.js');
The First One
extracts the exact function out of the module and sets it to the variable
The Second One
sets the whole module into the variable.
Instead of calling:
const SaveJson = require("./utilities.js")
SaveJson(ans)
You need to call the actuall named function that you exported like:
const Util = require("./utilities.js")
Util.mySaveJson(ans);
Also, if you export multiple functions in utilities.js
like:
exports.mySaveJson = function(obj) {
...
}
exports.getJson = function() {
...
}
Then you can easily call this utility functions in any js file like:
const Util = require("./utilities.js")
...
Util.mySaveJson(ans);
const data = Util.getJson();
