Update routing-controllers class-validator dependency to latest (0.9.1)

[rmuchall]

Please could you update the class-validator dependency to the latest version (0.9.1)?
If I use the latest version (0.9.1) and routing-controllers is still using the older version (0.8.5) then oddities occur as described in this issue by @NoNameProvided
typestack/class-validator#166

EDIT: should class-validator be a peer dependency?

As always, thanks for your awesome efforts guys :)

Last publish 5 months ago, it seems abandoned.

I hope not, since it's quite the best framework to get some architecture to the nodejs mess for bigger projects.

I have access to master branch but no access to npm to publish package.

So last year when I created the PR #315, I published it as @19majkel94/routing-controllers 😉
As routing-controllers has great build script, you can easily just fork the master, make your changes, change the package name and then just npx gulp package and npm publish in build/package folder 🎉

@19majkel94 I tried doing the same (created my own routing-controllers package on npm), and after npm dedupe I now only have one version of class-validator installed in the project (0.9.1), but I am still getting the error message about no metadata. Any suggestions on what else I can try?

[FSM1]

@MardariG will give it a try... are you using your version as part of the TypeORM stack?

Sorry I deleted the comment, didn't noticed 19majkel94 has published already another version;

https://www.npmjs.com/package/@mardari/routing-controllers

Yes, I'm using it in https://github.com/w3tecch/express-typescript-boilerplate boilerplate, as with official version validation of @Body is not working.

@MardariG I had also done the exact same with my package, and now I have replaced with your version of Routing-Controllers and I still get the metadata error log and no validation happens.

I am using the exact same boilerplate and not having any luck with the validation. Any ideas what else I could look at?

I have checked the app's node_modules, and there is only one version of class-validator in the root of the app's node_modules. I have also checked Routing-Controllers folder and there is definitely not a copy of class-validator in there. Im running out of ideas here.

FSM1 can you share your error trace?

[FSM1]

@MardariG not getting any errors. I just get a console log from class-validator that no metadata has been found, and a response of an empty ValidationErrors array, even though the request is invalid.

    @Post()
    @HttpCode(201)
    public async create(@Body({validate: true}) user: User): Promise<User> {
        this.log.info('Validating request');
        const valid = validateSync(user);
        console.log(valid);
   ......

the following is logged to console when executing:

No metadata found. There is more than once class-validator version installed probably. You
 need to flatten your dependencies.
info: [api:controllers\UserController] Validating request

FSM1 can you share your package.json also ?

FSM1 Strange, using this https://github.com/w3tecch/express-typescript-boilerplate template, all I have to change is replacing official routing-controllers with mine @mardari/routing-controllers .
That's it, and @Body() is validated. Maybe there is a problem with models maybe other settings idk.

You can clone a clean project and see what is different from yours.

[FSM1]

I have changed quite a bit from the original boilerplate (ripped out TypeORM and using Mongoose + Typegoose instead).

Class-validator should be quite agnostic to that though. I am using other annotations throughout the project without issue.

Think I am just going to give up on the W3tecch boilerplate and move on over to Nest.js, hopefully with a lot less issues and a bit more support.

thanks for the help @MardariG
