Simple proof of concept how to do SSR with raven-for-redux in SSR

raven-for-redux-SSR-example.js

// configureStore.js
export default function configureStore(initialState: State, Raven: any): Store {
  const middlewares = [
    // Other middlewares
    createRavenMiddleware(Raven, ravenMiddlewareOptions)
  ];
  // configure store
  return createStore(/**/);
}

// universalRaven.js
export interface UniversalRaven {
  captureException(ex: Error, options?: RavenOptions): *;
  setDataCallback(data: any, orig?: any): *;
  captureException(ex: Error, options?: RavenOptions): *;
}

// Mimic raven-js API
export class UniversalRavenNode implements UniversalRaven {
  raven: any;
  dataCallback: any => any = state => state;

  constructor(raven: any) {
    this.raven = raven;
  }

  // This is neccecary to get proper timing
  captureBreadcrumb = (data: any) => this.raven.captureBreadcrumb(data);

  setDataCallback = (callback: any) => (this.dataCallback = callback);

  captureException = (error: Error, extraData: any = {}) => {
    const data = this.dataCallback({
      extra: {},
      ...extraData
    });
    return this.raven.captureException(error, data);
  };
}

// server/render.js
function render(req: $Request, res: $Response, next: Middleware) {
  match({ routes, location: req.url }, (err, redirect, renderProps) => {
    // This will set the user context for the given request
    Raven.context(function() {
      // init react & redux stuff

      const raven = new UniversalRavenNode(Raven);
      const store = configureStore({}, raven);

      const respond = (error: Error) => {
        if (error) {
          raven.captureException(error);
        }
        // Render and return the
      };

      // Run all SSR requests
      prepareWithTimeout(app).then(respond, respond);
    });
  });
}

// client/index.js
import Raven from 'raven-js';
const store = configureStore(preloadedState, Raven);
