After create project using the generator, i built it in production environment and when i load the app the follow error appears.
ActivityLuisFlip commented on Oct 25, 2018 i run:
gulp build
in file dist/server/index.js change development to production:
--> var env = process.env.NODE_ENV = process.env.NODE_ENV || 'production';
cd dist
node server/index.js
next open localhost:8080
and get the error Awk34 commented on Oct 25, 2018 I was able to reproduce and fix this locally. Apparently it's an issue with webpack bundling.
Manually add the following to the top of your polyfills.ts file:
import 'reflect-metadata'; Reacted by João Marcos Duarte, Sina Aghajani, Syed Muhammad Taha, Bart, Ray Oleaga and Aviw Reacted by João Marcos Duarte and Syed Muhammad Taha Reacted by Aviw added a commit that references this issue on Oct 25, 2018This issue will close once commit 550b6f0 is merged into the 'master' branch.550b6f0 Awk34 commented on Oct 25, 2018 LuisFlip commented on Oct 26, 2018 i try the following:
import 'reflect-metadata';
// import 'core-js/es6';
// import 'core-js/es7/reflect';
import 'zone.js/dist/zone';
or
import 'reflect-metadata';
// import 'core-js/es6';
// import 'core-js/es7/reflect';
//import 'zone.js/dist/zone';
and other variants allways with reflect-metadata uncommented and the problem persists.
i don't have the nativescript-angular in my project.
Ther project is new and i dont have add any line of code.
other question, is this building in jit or aot?
if is in jit, how i build project with AOT?
Thanks Awk34 commented on Oct 29, 2018 LuisFlip commented on Oct 30, 2018 Replacing that lines fixed the issue.
Before the change, the dist/client files created by build have the following sizes:
After that replace, the build lines
why we a have three warnings because of the size (1.3~mb) and after the changes we got higher values but not showing any warning?
is this in AOT or JIT?
best regards and thanks Awk34 commented on Nov 2, 2018 That change isn't meant to fix the issue, just turn off minification so that we can debug the error better, but if the error goes away when you set Webpack to development mode, then it has to have something to do with minification for builds. koraysels commented on Nov 6, 2018 yeah the error ahs something to do with the reflect polyfill.. I have the same issue.
It Seems he cannot bootstrap the application correctly! If you set the buidlmode to development it will work and no error will be displayed. so we cannot debug it that way :( i can;t not have minified code in prodcution! koraysels commented on Nov 9, 2018 This is a problem with UglifyJs. If you set the webpack mode to 'production' it enabels UglifyJsPlugin and then it fails.. I tried differetn options for the UglifyJsPlugin but I cannot get it to work. I think the dependency injection breaks when minification is applied. Do we need some kind of annotation plugin ? Sina7312 commented on Nov 21, 2018 I did this at top of my app.ts file, and it solve the problem:
(commented out polyfills import, and add imports for reflect and zone.js)
import 'reflect-metadata';
import 'zone.js/dist/zone';
// import './polyfills';
LuisFlip commented on Dec 20, 2018 @Awk34 I solve the problem adding reflect-metadata on top of app.ts
app.ts:
import 'reflect-metadata';
import 'zone.js/dist/zone';
//import './polyfills';
LuisFlip commented on Dec 20, 2018 tschaffter commented on Apr 3, 2019 Moving the imports from polyfills.ts to app.ts solves the issue as suggested here by @LuisFlip.
The Uglifier is not the issue (the issue is still there when commenting it in webpack.make.js).
Solution
In webpack.make.js, declare polyfills before app in config.entry.
Before:
if (!TEST) {
config.entry = {
app: './client/app/app.ts',
polyfills: './client/app/polyfills.ts',
vendor: [
'lodash'
]
};
}
Now:
if (!TEST) {
config.entry = {
polyfills: './client/app/polyfills.ts',
vendor: [
'lodash'
],
app: './client/app/app.ts'
};
}
Here is what I have included at the top of ./poyfills.ts:
// Enable certain polyfills depending on which browsers you need to support
import 'core-js/es6';
import 'core-js/es7/reflect';
import 'zone.js/dist/zone';
