How do I download a File/Blob or data URL from React Native on IOS?

I'm trying to programmatically download a PDF file from the browser, but every time I get an error saying that it was not able to download the file.
I tried to download both Blob and using data URI.
Data URI for example fails saying:
Error: Unable to open URL data:application/pdf... Add data to LSApplicationQueriesSchemes in your info.plist
The code I'm trying to run is an injected JS that tries to download the file.
The code works well in Chrome.

Load local JSON File into a HTML template

I'm trying to load a json file into to an html template, so I can view the content in a formated way inside my browser. The json file is generated by a Java project. I already tried to do this with javascript but it seems to be that java only can fetch a json file from a server and not from a local directory. Is their any way to do this with javascript or typescript or maybe something else?

You can use fetch API to retrieve the informations of your JSON and if you use VSCode you can just launch the plugin Live Server to test it in your local directory.
fetch('http://example.com/movies.json')
.then(response => response.json())
.then(data => console.log(data));

You can use fetch to retrieve it from a remote server or have a <input type="file" ... /> and let the user pick the JSON file using the "Open File" file browser dialog.
You can also include the JSON file from disk at compile-time when compile the application using TypeScript.
There are also the File API, FileReader API, and FileSystem API to manage files locally on disk at runtime. But these might only be able to read files written by the web browser that reside in certain locations and might not be able to access any file on file system due to security and sandboxing.

How to download pdf file using vuejs and bootstrap-vue

I'm trying to upload a pdf file to my browser, but I want to be able to download this file afterwards. I am having problems on the second task - downloading it.
I'm uploading as follow:
<b-form-file v-model="form.file" :state="Boolean(form.file)" placeholder="Choose a file..."></b-form-file>
How can I download form.file content after upload is done?
Edit:
I found this API, which handles file downloads nicely.

You need to save the file somewhere on your server or on a storage service (ie Amazon S3) and then redirect the user to a link where the file itself is served.
The specific implementation is based on your backend implementation and your architectural choices.

Read File stored on some URL using HTML5 File API

I'm using HTML5 file API to upload files to my web application.
I have an input element on my web page using which I read files and call upload function
<input type="file">
$('input[type="file"]').on("change",function(e){
console.log(this.files);
// upload each file in this.files
});
This works perfectly for native files on os. I want to now upload remote files e.g., example.com/blah/file1.jpg My question is how do I read this file using File API? Is there a way to do it?

You can download remote files over XMLHttpRequest, and process them as Blob. Then upload it to another server. The upload has to be over XMLHttpRequest. It relies on the browser's implementation of XHR Level 2. This link contains the code snippets you will need:
http://www.html5rocks.com/en/tutorials/file/xhr2/
It has both snippets for downloading remote file as a Blob and uploading a Blob to a server.

Can i upload and save an image file in file system ,and retrieve it back with javascript or HTML?

I am creating a webpage, which will be running locally.It will upload a file from local file system and save it in a specific location in that file system.But I do not want to use any language which require any other installation such as DBMS or web host e.g. JavaScript or Ajax which do not require any installation and can be processed by the browser only.

No. You cannot normally access to filesystem with client-side Javascript.
But! ..
.. you can with Javascript on server
(NodeJs with FS API http://nodejs.org/api/fs.html)
.. and you can, but only in Chrome and only with chrome.fileSystem api.
