Integrating angular2-apollo into the Angular2 quickstart project

[pso-aeb]

node/npm/angular2 beginner here.

I did the Angular2 Tutorial at https://angular.io/docs/ts/latest/tutorial/ I am now trying to integrate angular2-apollo into this project.

Yet, the Angular2 setup (with SystemJS) does not seem to work with angular2-apollo.

I tried both "npm install angular2-apollo" and including it in my package.json. The install was successful and I have all necessary files in my node_modules folder (.js etc). But as soon as I my code has an import from angular2-apollo (or from apollo-client) I get a 404 on Client-side. I tried including the angular2-apollo modules via SystemJS, but that just leads to further missing modules which lead to further missing modules, and so on.

Can somebody provide any help?

@pso-aeb I'm not that familiar with SystemJS but in the very next release of angular2-apollo there will be only 1 dependency: lodash and 2 peer dependencies: apollo-client and @angular/core.

So it would be easier for you to install angular2-apollo.

If a problem with missing modules of apollo-client will remain then you should talk directly to guys from that library.

Thanks for your answer!

I managed to get it running by now. The solution is to actually add all dependencies in the SystemJS config.

Hi @pso-aeb !

Isn't it painful to add every indirect dependency manually? Does SystemJS suppose to work that way?

[pso-aeb]

It is somewhat painful, but doable. I am not an expert in SystemJS, but it seems that way. You can also use SystemJS to create a single minified JS-file, so it somehow needs to know all required packages and how to include them.

@pso-aeb I think it would be a good idea to reopen this thread. SystemJS is supposed to be able to load node_modules with subdependencies however I didn't got it working with angular2-apollo yet. However I guess its ways more convenient to load the library and let the sub dependencies automatically be loaded.

[manuelfink]

@pso-aeb got an message you uploaded an config file as sample ... however its not here any more. Can you share it again?

[pso-aeb]

@manuelfink Upload is blocked by the local network setting. I will upload when I am at home

config.zip Config files that worked for me.

I've created a PR for angular.io with live example using the Angular quickstart. Check this out here is let me know if it helps - https://github.com/Urigo/angular.io/tree/graphql-cookbook/public/docs/_examples/heroes-graphql It's very some configurations that are specific to the structure of the website but I believe it would still be useful. Hope to get it merged soon for everyone to enjoy

[pabx06]

@Urigo you are my hero! found the minimal subset of systemjs.config.json that worked for me from your files!

I am getting 404 error when apollo client requestion OPTIONS HTTP METHOD on my endpoint that work well using graphiql

Graphiql send POST:

also forget to say: my app is localhost:3000 graphql is localhost:8080. found noting about CORS in apollo documentations :

[stubailo]

You need to set up your web server to support CORS. That's not Apollo specific at all. If you're using express, you can use the cors NPM package for that.
