[semantic-release] ![FlowType compatible] The ReactRelayNetworkLayer is a [Relay Network Layer] with various middlewares which can manipulate requests/responses on the fly (change auth headers, request url or perform some fallback if request fails), batch several relay request by timeout into one http request. ReactRelayNetworkLayer can be used in browser, react-native or node server for rendering. Under the hood this module uses global fetch method. So if your client is too old, please import explicitly proper polyfill to your code (eg. whatwg-fetch, node-fetch or fetch-everywhere).

QUESTION
This is very frustrating. I've been dealing with this issue since yesterday morning. I have a React application I have not started up in over a year. This application ran perfectly last time I started it up. But I want to work on it locally, and using the exact same package.json when it ran just fine a year ago, is failed in the browser with the following error message:
...ANSWER
Answered 2019-Feb-18 at 18:34So what you're running into is the way that npm modules work - this issue that you're having isn't exclusive to react. We can't be expected to solve this for you - but I can try to point you in the right direction.
I'll use the dependency in your package.json as an example, the line:
"react-error-overlay": "^1.0.10" has a caret (^) next to the version number.
This means when you run npm install in most cases, or npm update then npm will go grab the most recent version of that package, above that version number.
If you compare the two different package.json files in your post you will notice that there are multiple major package versions skipped for quite a few of your dependencies. If you look up semantic versioning you'll find that a major version bump usually is due to a breaking change in the module.
E.g:
Old: "react-error-overlay": "^1.0.10"
New: "react-error-overlay": "^5.1.3"
In here you are jumping from major version 1.x.x to 5.x.x. That is over 4 breaking changes for just this module alone.
Basically, this means that the module does not work in the same way it did before. If you project worked a year or so ago - and you ran npm update - it most likely will fail now as you're pulling in new major package versions.
If you just want your project to work as it did before, here is what I recommend:
Take the original version of your package.json and remove the ^ carets in the version numbers.
Then clear out your node_modules folder in your project.
Then run npm install.
This should pull in the module versions very similar to what you were working with before. Try and see if it runs then. If it does, update your dependencies individually from there - and find which major version bumps cause your project to break.
Also:
As for the typeError you are getting - it stems from react-konva as noted in this issue thread:
https://github.com/konvajs/react-konva/issues/147#issuecomment-346217504
react-konva above version 1.1.6 is for react v16 and above
Target react v15 by using the version:
"react-konva": "1.1.6"

I have a React application I have not started up locally, in over a year. This application ran perfectly last time I started it up. And the application continues to run today in Heroku's cloud. But I want to work on it locally, and using the exact same package.json when it ran just fine a year ago, is now failing in the browser with the following error message:
...ANSWER
Answered 2019-Feb-18 at 14:56Probably one of your dependencies made a breaking change and either your own package.json or one of the dependencies you work with did not restrict the version of the dependencies you rely on. I would suggest checking the individual libraries throwing the error to make sure that the configuration you passed for those libraries are still valid for the version you are using.

I am following along a Lynda.com tutorial called "Building and Deploying a Full-Stack React Application", and in the chapter "Injecting the Relay Network Layer" there is in index.js, an attempt to set up a network layer, and the program compiles successfully but I'm receiving the following error in the browser:

Any ideas? I'd appreciate it, CM

Answered 2017-Aug-15 at 22:56You are probably not using the right version of Relay, but its just a guess. Check if the tutorial specifies any version and check which one you are using.
A lot of things changed in the last version of Relay: Relay-Modern. You might want to look into that, its way more convenient and efficient than Relay-Classic.
Also there are easier ways to combine a router with relay. Create your Relay Environment directly above or below your router, depending on if you need to get routes out of your db. But I guess you just need to get through the tutorial.
QUESTION
In Relay Classic, we would just pass a function to react-relay-network-layer to return the required token in a promise. What's the equivalent in Relay Modern?
Ideally I'd like to display the Loading screen until the Environment promise resolves, and then display the main Component once we have an Environment and the query is fetched.
So if I knew how to swap out QueryRenderer's environment, that would also solve the issue.
...ANSWER
Answered 2017-May-18 at 19:56The recommended method here is to fetch the authentication token inside of fetchQuery.
The remaining challenge is how to make sure the async authentication function is called only once, even if Relay fetches multiple times while authentication is still ongoing. We did this using a singleton promise; each call to fetchQuery calls the static Promise.resolve() method on the same promise, so that once the authentication call finishes, all fetchQuery calls continue with the desired authentication information.
So fetchQuery gets an auth token (JWT) with:
