If you insist on running the  html file locally and not serving it with a webserver  you can prevent those cross origin requests from happening in the first place by making the problematic resources available inline   I had this problem when trying to to serve  js files through file     My solution was to update my build script to replace  lt script src       gt  tags with  lt script gt     lt  script gt   Here s a gulp approach for doing that   1  run npm install --save-dev to packages gulp  gulp-inline and del   2  After creating a gulpfile js to the root directory  add the following code  just change the file paths for whatever suits you    let gulp   require  gulp    let inline   require  gulp-inline    let del   require  del     gulp task  inline   function  done        gulp src  dist index html        pipe inline           base   dist            disabledTypes   css  svg  img               pipe gulp dest  dist    on  finish   function            done                 gulp task  clean   function  done        del   dist   js        done        gulp task  bundle-for-local   gulp series  inline    clean       Either run gulp bundle-for-local or update your build script to run it automatically    You can see the detailed problem and solution for my case here

Easy solution for whom using VS Code  I ve been getting this error for a while  Most of the answers works  But I found a different solution  If you don t want to deal with node js or any other solution in here and you are working with an HTML file  calling functions from another js file or fetch json api s  try to use Live Server extension    It allows you to open a live server easily  And because of it creates localhost server  the problem is resolving  You can simply start the localhost by open a HTML file and right-click on the editor and click on Open with Live Server   It basically load the files using http   localhost index html instead of using file         EDIT  It is not necessary to have a  html file  You can start the Live Server with shortcuts      Hit  alt L  alt O  to Open the Server and  alt L  alt C  to Stop the server   On MAC  cmd L  cmd O and cmd L  cmd C    Hope it will help someone

Just to be explicit - Yes  the error is saying you cannot point your browser directly at file   some path some html  Here are some options to quickly spin up a local web server to let your browser render local files  Python 2  If you have Python installed      Change directory into the folder where your file some html or file s  exist using the command cd  path to your folder Start up a Python web server using the command python -m SimpleHTTPServer   This will start a web server to host your entire directory listing at http   localhost 8000   You can use a custom port  python -m SimpleHTTPServer 9000 giving you link  http   localhost 9000   This approach is built in to any Python installation   Python 3  Do the same steps  but use the following command instead python3 -m http server  Node js  Alternatively  if you demand a more responsive setup and already use nodejs      Install http-server by typing npm install -g http-server Change into your working directory  where yoursome html lives  Start your http server by issuing http-server -c-1   This spins up a Node js httpd which serves the files in your directory as static files accessible from http   localhost 8080  Ruby  If your preferred language is Ruby     the Ruby Gods say this works as well   ruby -run -e httpd   -p 8080   PHP  Of course PHP also has its solution   php -S localhost 8000

For those on Windows without Python or Node js  there is still a lightweight solution  Mongoose   All you do is drag the executable to wherever the root of the server should be  and run it  An icon will appear in the taskbar and it ll navigate to the server in the default browser   Also  Z-WAMP is a 100  portable WAMP that runs in a single folder  it s awesome  That s an option if you need a quick PHP and MySQL server

One way it worked loading local files is using them with in the project folder instead of outside your project folder  Create one folder under your project example files similar to the way we create for images and replace the section where using complete local path other than project path and use relative url of file under project folder   It worked for me

I m going to list 3 different approaches to solve this issue   Using a very lightweight npm package  Install live-server using npm install -g live-server  Then  go to that directory open the terminal and type live-server and hit enter  page will be served at localhost 8080  BONUS  It also supports hot reloading by default  Using a lightweight Google Chrome app developed by Google  Install the app then  go to the apps tab in Chrome and open the app  In the app point it to the right folder  Your page will be served  Modifying Chrome shortcut in windows  Create a Chrome browser s shortcut  Right-click on the icon and open properties  In properties  edit target to  quot C  Program Files  x86  Google Chrome Application chrome exe quot  --disable-web-security --user-data-dir  quot C  ChromeDevSession quot  and save  Then using Chrome open the page using ctrl o  NOTE  Do NOT use this shortcut for regular browsing   Note  Use http    like http   localhost 8080 in case you face error

My crystal ball says that you are loading the model using either file    or C    which stays true to the error message as they are not http     So you can either install a webserver in your local PC or upload the model somewhere else and use jsonp and change the url to http   example com path to model  Origin is defined in RFC-6454 as         they have the same    scheme  host  and port    See Section 4 for full details     So even though your file originates from the same host  localhost   but as long as the scheme is different  http   file   they are treated as different origin

cordova achieve this  I still can not figure out how cordova did  It does not even go through  shouldInterceptRequest   Later I found out that the key to load any file from local is  myWebView getSettings   setAllowUniversalAccessFromFileURLs true    And when you want to access any http resource  the webview will do checking with OPTIONS method  which you can grant the access through WebViewClient shouldInterceptRequest by return a response  and for the following GET POST method  you can just return null
