Is there any ways to compress a file from my_file.txt to my_file.zip using ionic 3? I've found the ionic plugin that only can unzip the files but not to zip the files.
Reference:
https://ionicframework.com/docs/native/zip/
Anyone? Thanks for any helps or comments.
I would suggest client zip, You can fetch your text file in the downloadzip()
function , and this function will return you a zip blob file which you can convert into a zip file.

Let say I have a zip archive test.zip which contained two files:
test1.txt and text2.txt
I want to extract only test1.txt using the node inbuilt zlib module.
How to do that?
I don't want to install any package.
You could run a shell command to unzip, assuming that unzip is installed on your system. (It very likely is.)
As far as I can tell, there is no zip functionality within node.js without installing a package.
You can use zlib to help you with the decompression part, but you will have to write your own code to interpret the zip format. You can use zlib.inflateRaw to decompress the raw deflate compressed data of a zip entry. You have to first find where that compressed data starts by reading and interpreting the zip file headers.
The zip format is documented here.
I am downloading a zip file from an API and trying to unzip it using Python shutil.
shutil.unpack_archive(file_name)
It gives weird behaviour, for some files it works, for others it shows the following error:
name.zip is not a zip file
There is no issue with the downloaded file, I am able to unarchive it manually.
Any help here would be appreciated.
You should use zipfile (for zip archives) or tarfile (for tar archives)
Is there any node library which able to unzip split zip files? Or any other way? I have tried a lot of node libraries but no luck.
I am receiving files like below.
test.z01
test.z02
test.zip
I need to extract these files.
I am writing a nodejs script which should do the following:
Replace 10 or more bmp files within the zip
Because the zip file is large, I would like to replace the files without unzipping and rezipping the file.
Is that possible?
I use the adm-zip(Module NodeJs ) to zip Floder, with Method addLocalFolder().The operation end successfully, but when i try to unzip folder i get the Error 2 ' file or directory not exist!'as additional info i have the right size of zip when zip operation is end.
Thank you every one.
The archive files produced by adm-zip do not seem to work on certain systems. Try this: https://stackoverflow.com/a/15532326/1134405
