QUESTION
I am facing some issues with appending data into csv file.
First the data is retrieved from a webpage using cheerio. But when I want to execute a function to check whether the file exists/accessible, I cannot run the function in the class. Even when I pass the data to the third function writeDataIntoFile(), it still shows the same error.
Here is the code:

Use arrow-function.

QUESTION
I am creating a project in Node JS and Typescript in which I want to download a CSV with the information that an API contains in JSON format. Given the url http://localhost:3000/?api=api1, I have to read the JSON related to api1.
I have added the modules that I have seen that are necessary but I cannot download the CSV from an external JSON by url.
This is my controller:
ANSWER
Answered 2021-Jun-06 at 15:28You can call that url using axios or request, after getting the JSON in response you can use https://www.npmjs.com/package/json2csv to convert JSON to csv.
QUESTION
I am starting to develop with Node JS and I am creating an application to achieve the following:
Download a CSV with the JSON information found in an API. I have an internal file that contains the url where the JSON is located, I need to extract the information from that url and download it in CSV. I am using the json-2-csv, node-fetch and fs modules.
My problem: I cannot access the information contained in the JSON to download it
This is my controller:
ANSWER
Answered 2021-Jun-07 at 07:54The problem is that you never call your getJson function, i.e. a call like const jsonResponse = await getJson() is missing. It's not really necessary to do this in a separate function though. After getting the json, you need to pass it to the csv-converter and finally send the response through the res-object.
Here's a simplifed example (still needs error-handling) that fetches a json from a fake rest-api and converts it to csv and allows the user to download it:
QUESTION
I have a project in Node JS in which I want to export the data contained in the database in Mongo DB in a CSV file through a button in the view (index.ejs).
I am using mongoose for the connection to the database and to export the data to the CSV I am trying to use json-2-csv.
In the button I have added a url to be able to call that url through the button and that the json-2-csv function responds to that url but I don't know how to do it or if it is the best way.
This is my app.js:
ANSWER
Answered 2021-May-31 at 05:22You can achieve all these things in your single file app.js file. We need to have json2csv module because this module has the parser class so that we can use parse() method to get the CSV format data as String. Here lean options tell mongoose to skip instantiating a full Mongoose document and just give you the Plain Old JavaScript Object POJO. And also I have used username and password as documents so change it accordingly.
QUESTION
I have a project with Node JS in which I am collecting the information of a JSON by http using the node-fetch module.
This is the way I have found to use the node-fetch module with async, if it is possible to improve this function, suggestions are added, I am new to this module.
This is my code where I read the information:

Answered 2021-May-24 at 17:32const { Parser } = require("json2csv");
const fetch = require("node-fetch");
const fs = require("fs");
const csvLimit = 3;
const getJson = async () => {
const response = await fetch("https://jsonplaceholder.typicode.com/users");
const responseJson = await response.json();
return responseJson;
};
const jsonToCsv = async () => {
const json = await getJson();
const json2csvParser = new Parser();
let i = 0,
j = 0;
while (j < json.length) {
let csv = [];
let temp = [];
for (j = i * csvLimit; j < (i + 1) * csvLimit; j++) {
temp.push(json[j]);
}
csv.push(json2csvParser.parse(temp));
fs.writeFileSync(`file${(i * csvLimit) / 3}.csv`, csv);
i++;
}

jsonToCsv();
