The thing I absolutely like about nodejs and its packet is that you can screw up the whole project just by updating something.
Did anyone successfully updated aurelia components for an old project and get it successfully built?
Please share your experience!
By the way, my setup: Babel + Webpack
Be careful of what you rant, you may attract an unexpectedly large crowd. Now for your actual issue, it’d be easier to help if you could share some error to start. I’m pretty sure folks here have a lot of experience fixing this. Someone recently also shared they got back to a project after 2 or 3 years and the only thing that broke was webpack 
Indeed. It’s not imposible, though depending on usage of not-so-public methods of the packages. We have updated most of our project in the beginning of this year. So please share your problems, willing to help! 
Sorry for late reply.
Guys, thank you for your answers 
yeah, indeed npm became better for the past 5 years, but for the package stability prospective, there is still a lot to be desired 
@bigopon, it is probably a webpack issue, do you have the link on that tread?
Without further ado, here is the yarn outdated output:

After this au build will run without any issues, but in browser there is an error while apllication startup:
Any ideas?
This means a module is referenced too early, before platform initialization module has a chance to run. When platform has not been initialized, it typically results in some error like DOM.something is not a function.
What you can do is to check your webpack configuration to ensure the entry point is aurelia-bootstrapper.
If you are not using bootstrapping via aurelia-bootstrapper, then maybe share your main.ts
Maybe share yuor main.ts?

That’s weird. Can you try add this to the top
import { initialize } from 'aurelia-pal-browser';
initialize();
of main.ts?
Yeah, it probably should be refactored to get rid of all those css imports
Unfortunately, got the same error.
As I can see from trace, the last call frommain.js was aurelia.start().
So I’ve imported DOM into main.js
import { PLATFORM, DOM } from 'aurelia-pal';
And add a console.log(DOM); just before aurelia.start().
After I removed manual initialization - got the same output.
I’ve modified the original node_modules/aurelia-loader-webpack/dist/native-modules/aurelia-loader-webpack.js:
Surprisingly, the output of that calls was just an empty object.
oh I see. Probably you got some duplicated modules/dependencies. Maybe run npm dedupe or delete node_modules and package-lock.json and do npm i
Little remark/question: have you added a breakpoint on the aurelia.start() line as well? The [i] at the end of the console.log(DOM) means that the content of the variable is evaluated at the moment you watch the details. This still means that the variable can be empty when the console.log is performed.
Well, https://yarnpkg.com/en/docs/cli/dedupe/ 
I’ve removed node_modules and yarn.lock, and install everything again.

BTW: I’ve rolled back original lock file. toposort version there is 1.0.7
Without knowing much details, I would suggest try a different possible easier approach.
npm i -g aurelia-cli to get latest aurelia-cli.au new to create a new project, select options to match your existing app.Make the app run first, then update webpack.config.js bit by bit if you have some custom config.
BTW, latest skeleton does not use Bluebird anymore (it causes few hiccups and performance issue), it now uses promise-polyfill. You need to uncomment a line in webpack.config to support IE11.
@huochunpeng thank you for your input.
Though, your solution may work, but it kind of defeats the purpose - updating the project.
See
There is a lot to configure there.
I am just wondering, is there anyone with the experience in updating the project.
If we go back to your original error, the easiest way is to do the equivalent of
npm ls aurelia-pal
to see which dependency is using duplicate aurelia-pal. and then in your webpack config, alias aurelia-pal to a single version:
resolve: {
alias: {
'aurelia-pal': path.resolve(__dirname, 'node_modules/aurelia-pal')
}
}
maybe that’ll help
