I am working with Angular 5, I have an application in which I need to read an AMP HTML file as text. This file is contained in a component and should only be accessed from this component.
I would like to be able to open the file in read-only by giving its name.
I'm actually searching for something like this:
let file = open('amp.html');
Is it possible? If not how can I do to achieve this?
You can't just simply read a file. The JS is running on your browser, and you need to think about where you're getting that file from.
If the file is on a server, you need to fetch that file from the server first by making a request for it.
If you're reading a file on the user's computer, you're gonna be using the File API on the browser to allow the user to select that file.
Assuming you're using NodeJS, you can conduct file operations like you would with other programming languages. Check out the fs module
If i understand you correct, you can read it as text like this:
function readFile(file){
var raw = new XMLHttpRequest(); // create a request
raw.open("GET", file, false); // open file
raw.onreadystatechange = function (){ // file is ready to read
if(raw.readyState === 4){
if(raw.status === 200 || raw.status == 0){
var allText = raw.responseText;
alert(allText); // can be also console.logged, of course.
}
}
}
raw.send(null); // return control
}
usage:
readFile('link.html')
I solved this issue thankfully to this question.
fsmodule to read and write from a file.
