QUESTION
I'm using json2csv
v5.0.6 for a small project and I wanted to format some values using custom formatters so I get a clean CSV file.
However, I can't seem to make the formatters work. I have one number
formatter and one string
formatter that are supposed to be called upon parsing. Here's a sample test file that reproduces this behaviour, with two simple formatters:
ANSWER
Answered 2021-Dec-30 at 11:02You have to use the alpha version : json2csv@6.0.0-alpha.0
The last released version has some issue with formatters : https://github.com/zemirco/json2csv/issues/521 (they are not exported)
And you also have to call your formatters functions

I would like to put all jq filters inside a text file and use the jq -L

ANSWER
Answered 2021-Oct-08 at 17:40Use jq -f json2csv
instead.
From man jq
:
-Ldirectory / -L directory:
Prepend directory to the search list for modules. If this option is used then no builtin search list is used. See the section on modules below.
Compare this to:
-f filename / --from-file filename:
Read filter from the file rather than from a command line, like awk´s -f option. You can also use # to make comments.

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

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.

I wanted to scrape a website's data, so I tried it using cheerio
npm package
The selector works perfectly fine in chrome dev tools
ANSWER
Answered 2021-Feb-24 at 10:46In the http headers, you've specified "accept-encoding": "gzip, deflate, br"
which means you want the request result to be compressed as gzip. Cheerio is expecting text and thus can't parse the response data.
Just removing that header makes it work :
