I'm new to Ionic. I have started project with super template. But when I try to run the app in browser. It throws an error saying:
ReferenceError: webpackJsonp is not defined
at http://localhost:8100/build/main.js:1:1
I have tried putting vendor.js in index.html but that has not worked.
Here's the index.html file. I have removed vendor.js as it didn't work.

Reset to default 113Literally just went through the same thing as you are. I added the vendor.js script BEFORE the main.js in /src/index.html - now it runs locally.
<!-- The polyfills js is generated during the build process -->
<script src="build/polyfills.js"></script>
<script src="build/vendor.js"></script>
<!-- The bundle js is generated during the build process -->
<script src="build/main.js"></script>
This is a breaking change in Ionic-App-Scripts
https://github.com/ionic-team/ionic-app-scripts/releases/tag/v2.0.0
src/index.html must be modified to include a new vendor script tag .
...
<body>
<!-- Ionic's root component and where the app will load -->
<ion-app></ion-app>
<script src="cordova.js"></script>
<!-- The polyfills js is generated during the build process -->
<script src="build/polyfills.js"></script>
<!-- all code from node_modules directory is here -->
<script src="build/vendor.js"></script>
<!-- The bundle js is generated during the build process -->
<script src="build/main.js"></script>
</body>
...
Add vendor.js path within the script tag in < your application directory > /src/index.html
<script src="build/vendor.js"></script>
Also make changes in < your application directory >/src/service-worker.js File - Include vendor.js in the precache section:
// pre-cache our key assets
self.toolbox.precache(
[
'./build/main.js',
'./build/vendor.js', // <=== Add vendor.js
'./build/main.css',
'./build/polyfills.js',
'index.html',
'manifest.json'
]
);
I face the same issue when i started developing old ionic 2 project with ionic 3.
follow this steps works for me.
opne src\index.html
put this line
<script src="build/vendor.js"></script>
before
<script src="build/main.js"></script>
and after
<script src="build/polyfills.js"></script>
like this
<!DOCTYPE html>
...
<body>
<!-- Ionic's root component and where the app will load -->
<ion-app>
</ion-app>
<!-- The polyfills js is generated during the build process -->
<script src="build/polyfills.js"></script>
<script src="build/vendor.js"></script> <---- here
<!-- The bundle js is generated during the build process -->
<script src="build/main.js"></script>
</body>
</html>
npm install -g [email protected]
or
yarn add -g [email protected]
Ionic version problem bro.
check the version.
npm install -g [email protected]
npm install -g [email protected]
npm install -g ionic@v1
I was working on a ReactJs project when I faced this error. This could be a case of missing dependencies from package.json file which eventually bubbles up in the form of error reported by OP. In our case a reference to omitJs npm package was missing. The moment I added below line in dependencies section of package.json file it all started to work:
"dependencies": {
.....other dependencies
"omit.js": "1.0.0"
}
I just have faced this issue, and the order of the files polyfills/vendor/main doesn't anything has to do in my case, but it was the size of the vendor.js file.
I did realize it because it works on my local machine, so, I did find that vendor.js was 5MB, so, I builded again the app using --prod parameter:
ionic cordova build ios --prod
