I am trying to upload my images to Cloudinary using the Cloudinary's node.js module.
The problem is that Cloudinary depends on "crypto" module that is present in node.js environment as a global property and in NativeScript, of course, it isn't.
I tried:
installing crypto manually with npm install crypto --save and moving it into node_modules/cludinary/node_modules to no avail
I manually changed every reference to crypto in node_modules/cloudinary from crypto = require('crypto'); to crypto = require('./crypto'); to no availtoo :(
The question is how can add global dependencies of a pure node.js module in NativeScript?
EDIT
For those looking for a "perfect" solution. In the end I am POSTing base64 version of the image to an endpoint on our server where I use Cloudinary library (GEM) to communicate with Cloudinary service. Since I have to go through my server anyway to save references to the new image there is no overhead that this approach brings...

I set up an laravel application at AWS Lambda, using Bref. Everything works fine, including filesystem and s3 filestorage. I use spatie's medialibrary to handle file upload and media conversions, and I can upload a file without any troubles.
The problem appear when I try to make image conversions, using either GD or Imagick.
Whenever I try to make the conversions, I get the following errors:
When using Imagick:
Intervention\Image\Exception\NotReadableException
Unable to read image from path (/tmp/Glide0PSwRU).
When using GD:
Intervention\Image\Exception\NotReadableException
Unsupported image type. GD driver is only able to decode JPG, PNG, GIF or WebP files.
This only happens when running the application at AWS Lambda. If I run at my local environment or at another service like Google App Engine, with the "same" code configs (related to the upload/media conversion).
Create a php/conf.d/php.ini in your project
then add extension=imagick or extension=gd to enable these extensions

has anyone used the streaming json in nativescript? I found this http://oboejs.com/why but it seems not to work. I'm using nativescript 1.6, any suggestion would be appreciated really much. Thank you.
There is no library to my knowledge currently built for NativeScript that allows streaming JSON. Just for clarification sake you can easily pull JSON from a server and parse it using the built in fetch/http api's, right now -- but their is no way to have it start parsing the json as it downloads in chunks built in.
You can attempt to modify the npm node module to build for NativeScript.
Or thinking outside the box a bit; you can also use the web based version of that module inside the nativescript-webworkers and have it pull and process your JSON and communicate the json messages back to the NS environment. The WebWorkers module actually wraps the native platform's web browser module so it can run all browser based JS code.

I want to get the image list and download those images from a Dropbox's public-shared-link, which I get it from my client.
I'm using Dropbox SDK for ruby and only find the methods to manage files via my Dropbox account, such as put_file, get_file, get_file_and_metadata, get_chunked_uploader, upload and so on.
Is there any way to do that?
Dropbox API v1 has an endpoint that allows you to retrieve metadata about shared links:
https://www.dropbox.com/developers-v1/core/docs#metadata-link
Dropbox API v2 has a similar pair of endpoints that allows you to retrieve metadata and file content, respectively, from shared links:
https://www.dropbox.com/developers/documentation/http/documentation#sharing-get_shared_link_metadata
https://www.dropbox.com/developers/documentation/http/documentation#sharing-get_shared_link_file
Unfortunately, none of these are currently implemented in the Ruby SDK. You can call them directly though, or modify the Ruby SDK to do so.
I am trying to add underscore to my mean.io application. I'm not sure where to link the js library to the page as it doesn't have a main html page like the Angular generator does.
I manually added it via the config/assets.json file and it works however the dev server keeps crashing saying _ is undefined (even though the web app uses the _ function ok and returns the data just before the dev server stops).
I asume I must be doing this wrong.
What is the correct way to add custom js libraries to a mean.io project?
In your package app.js file add
<your package>.aggregateAsset('js', '../<path_to_js_lib in "public/assets" folder>',{
absolute: false
});
Is it possible to use Npm-Modules on client-side?
More specifically:
I want to use node.js built-in crypto-module for encrypting a password the user enters and then send the encrypted password with a signature(/hmac) to my server.
I need to do it that way, because I must be able to retrieve the original password server-side, because afterwards I'm going to send it to a ldap-server, because the user should authenticate with the same username/password he is registered with on that server.
This is what I did:
created in packages/crypto/:
-package.js:
Package.on_use(function(api) { api.add_files('crypto.js',['server','client']);});
-crypto.js:
crypto = Npm.require("crypto");
It works fine on the server, but on the client it says "Reference Error: Npm is not defined".
So, is it possible to use the crypto-module on client-side?
Are there any alternatives for achieving this goal?
Thank you!
Edit:
Is there any good alternative for getting the password to the server in a secure way, so that the server can retrieve the original password?
I think doing the ldap()-request on the client-side (like:
if(checkLdap(usrname,password)){<login>} else{fail}) can be easily bypassed?
You can try to add the js-files you need on client-side from .npm folder under crypto's package directory.
So, your package.js file might look like this:
Package.describe({
summary: 'Description of your crypto package'
});
Npm.depends({
'crypto': '1.0.0'
});
Package.on_use(function (api) {
api.add_files('crypto.js', 'server');
api.add_files('.npm/node_modules/crypto/crypto.js', 'client');
});
You can use https://github.com/elidoran/cosmos-browserify now to archive this. I used wrapped packages before and it was real pain to update them and to create new ones. Now with browserify support I can include library with just several lines of code. See their example how to do it. I don't publish it here as it may be subject of change.
Its not possible to use Npm modules on the client side since Npm modules are extensions via node.js which only runs on the server end.
If you want to use a file like crypto you would have to make a client side only version and put it in /client/lib of your Meteor app
While this may be possible officially, Meteor doesn't support this.
You would have to include requirejs manually using this project: https://github.com/apendua/require
You can use browserify to build a .js bundle with all all the Npm modules you want on the client side. See:
