QUESTION
I have a docker container specifically for Ruby on Rails that is basically built from a Ruby docker container. After it runs bundle install and everything else successfully, it then tries to run npm install which tries to install puppeteer. This is the error I'm receiving below:
ANSWER
Answered 2020-May-21 at 18:46When we enter npm install puppeteer it installs the latest version which is 3.1.0. It seems something wrong with the latest version.
QUESTION
I've been trying to add a use case to my code in which I try to unzip a zip that is too large to fit in the disk space and I expect my code to throw ENOSPC. I've tried multiple libraries but none of them throw error rather fail silently without completing the zipping. I'd expect them to throw ENOSPC error but all the packages seem to log the first info statement which states that the unzipping has been started but nothing after that. Most of them create incomplete folders, whatever they could write before disk went out of space. Here is how my code looks like for each of the libraries.
My code using adm-zip:

Answered 2020-Apr-28 at 16:53After some trail and error on both Yauzl and unzipper, unzipper seemed to work (throw ENOSPC when ran out of disk space during unzipping) with the following code.
QUESTION
I'm trying to use nock in my tests to intercept the request calls i'm making from the native https module in Node.js. I'm using Promise.all to make two requests to the external server. I want my tests to intercept the calls, and check some of the form fields to make sure they're filled in as i want.
I have my class setup below (kept the most relevant parts of code in):
...ANSWER
Answered 2019-Jun-05 at 15:06When the post method of a Nock Scope is passed a second argument, it is used to match against the body of the request.
Docs for specifying the request body
In your test, you're passing a function as the second argument, but not returning true so Nock is not considering it a match.
From the docs:
Function: nock will evaluate the function providing the request body object as first argument. Return true if it should be considered a match
Since your goal is to assert form fields on the request, your best approach would be to leave the function there, do your assertions where the // console.log(body); line is, but add return true; to the end of the function.
You could also return true or false depending on if your form fields match your assertions, but in my experience it makes the error output from the test convoluted. My preference is to use standard chai expect() calls and let the assertions bubble errors before Nock continues with request matching.

QUESTION
I've located the end of a local file header in download stream of a large zip file that
- specifies
deflatecompression with - bit 3 set indicating the length of the compressed data follows the compressed data
and would like to now inflate that data using Node zlib but I cannot figure out how to feed data into zlib and receive feedback telling me when the deflate stream has self terminated.
Does Node's zlib library support consuming chunks of deflate data and returning a result letting the caller know when the deflate stream has ended?
Or is this an insane thing to do because it would imply I'm inflating on the UI thread and what I should really do is save the downloaded file and once downloaded use an NPM package? Hm.. well.. either the network is faster than inflation in which case streaming inflation would slow the network (bummer) or the network is slower than streaming inflation so why deflate while streaming (which I can't figure out how to do anyway) when I could simply saving to disk and reload-deflate while I'm sitting around waiting for the network..
Still, for my edification, I'd still like to know if Node supports streaming inflation.
...ANSWER
Answered 2019-Feb-26 at 07:04It looks like it does, since the documentation lists zlib.constants.Z_STREAM_END as a possible return value.

QUESTION
I try to find example where I can send a zip (like via postman)
and get this zip in my handler and unzip it so specified folder
I didn't find much examples for zipping using express
I want to unzip it in path web/app
I try something like the following which doesn't works for me , the zip file is not unzipped in the specified folder, any idea what im doing wrong ?
...ANSWER
Answered 2018-Jul-11 at 16:25Without a full example it's tough to say what the real problem is. But according to Express docs it says:
In Express 4, req.files is no longer available on the req object by default. To access uploaded files on the req.files object, use multipart-handling middleware like busboy, multer, formidable, multiparty, connect-multiparty, or pez.
So if you are not using a middleware library to handle uploading files, it's tough to tell what the value of req.file is.
I am also a bit worried that you are trying to use zlib to decompress a zip file, since the library only supports gzip.
The zlib module provides compression functionality implemented using Gzip and Deflate/Inflate
You would want to check for req.file.mimetype === 'application/gzip'
Here are some posts related to unzipping zip files:

I download a ziparchive from an api, which contains gzipped files, and i need to take the gz files and save to s3. Don't want to uncompress or anything. Just move to S3.
When i open the archive, it has a folder w/ random numbers, /12345/file1.gz, and many files, /12345/file2.gz, etc.
I've tried yauzl and adm-zip, but don't understand how to take each entry in the archive and just send to s3. I have s3-stream-upload package, which i can use to send. Just can't get it right. Thanks for any help

On Windows, I am trying to update ChromeDriver to take advantage of the new headless option for Chrome. However, ChromeDriver reverts back to a previous version as soon as the update is complete.
In the console log from command prompt below, you can see that I downloaded version 2.33, but at the end, the version I get is 2.27. I need at least 2.29 to use headless Chrome.
...ANSWER
Answered 2017-Dec-02 at 11:09Most probably you have another chromedriver in your PATH. You can use PATH command in cmd prompt to check if you have another chromedriver in your path. If you have another chromedriver you can either update it manually by downloading the version you want or you can add the one installed by npm to your PATH, which is at following location:
