QUESTION
Here, I am creating new ApolloClient with graphql
...ANSWER
Answered 2022-Mar-27 at 11:59the problem is with you are using customHook and that is the promise for graphql what it does is return the instance of that current runtime and it is undefined at that time all you can do is simply use in the component that you want to use why are you complexing things.
QUESTION
I'm writing a toy app to learn more about Serverless Framework and AWS AppSync etc.
I'm trying to do TDD as much as possible. I'm using mock-apollo-client to mock the ApolloClient, and I've run into a problem. When trying to write a test to make sure the arguments to the query are passed, the test always returns a 401 Unauthorized error. It seems as though the real end point is still being called, because when a valid x-api-key is added to the instantiation of the ApolloClient, the test returns the real value from the AppSync server, and not the mock value I'm expecting. I'm using a mock, not spy, so I'm not expecting the real end point to actually be hit. Furthermore When I do add a valid x-api-key the test fails because the function is never called.
ANSWER
Answered 2022-Mar-25 at 08:52mock-apollo-client always use the with ApolloProvider, so that you pass the mock apollo client via React context Provider to descendant components.
However, your code cannot pass the mock apollo client to the component in this way. Your code initiates requests directly from the Apollo Client. We need to intercept these GraphQL requests. There are several ways to do this such as msw. However, I'll continue to use the mock-apollo-client library to demonstrate.
You need to mock ApolloClient class of the @apollo/client module. We need to use Mocking Partials, we don't want to mock other things exported from @apollo/client. Since the mock-apollo-client library already provides createMockClient function to create mocked apollo client, we don't need to mock by ourself.
An working example:

QUESTION
Contrast in "apollo-client in next.js" approaches chosen in next-with-apollo npm library and the approach shown in next.js docs.
The link of approach chosen by next.js for apollo client: https://github.com/vercel/next.js/blob/canary/examples/with-apollo/lib/apolloClient.js
- no third-party library next-with-apollo is used
- no get-data-from-tree is used
- Moreover i found this approach more meaningful and elegant inner-working of client side redering and SSR of apollo-client in next.js. I strongly like this
Some cons in next-with-apollo approach
- in next-with-apollo docs, it is stated that in withApollo API, the parameter getDataFromTree of intialState defaults to undefined by implementaion and its stated "It's recommended to never set this prop, otherwise the page will be a lambda without Automatic Static Optimization "
- get-initial-props is used which is not recommended by next.js for optimization reasons general thing. Why to consider third party library if there is non-third party way and suggested officially unless it has drawbacks?
It made me really curious to see many are using next-with-apollo and rarely seen the usage of the approach shown in next.js docs? I'm curious whether approach in next.js docs has any drawbacks (which i strong think of not having any)?
- does the approach shown in next.js has some drawbacks?
- does next-with-apollo has more efficiencies? if so what r those more efficiencies for which it is wise not to choose next.js doc approach. I wanna be sure that if i'm rejecting next.js doc approach (currently im choosing it) i'm not doing any wrong
So which is better for both client-side data fetching and server-data fetching to support both CSR and SRR?
...ANSWER
Answered 2021-Aug-20 at 17:34I found the answer by posting in next.js community:
Here it goes:
next.js doc's apollo examples avoid using getDataFromTree because it traverses the react tree twice in order to trigger all the queries and collect their result afterwards.
The drawback of using the approach on the next.js doc's apollo examples is since you don't use
getDataFromTree, you have no way to know which queries your inner components are using. So you need to remember to prefetch everything you need ongetStaticProps/getServerSidePropsand match the exact same queries/variablesnext.js doc's apollo examples way is recommended instead of
getInitialPropsso I would always use them unless one has some very specific reason not to

When I see sample apps which uses Apollo-client I see following constructor.When I read HttpLink document, it seems that graphql endpoint must be set as uribut in following code, I couldn't find them.

Answered 2022-Feb-16 at 17:53The HttpLink constructor option uri has a default value of /graphql. So as long as that is the correct path it will work without passing a uri option into the constructor.

QUESTION
I have a React project using Babel and Webpack. Recently I realized that my webpack wasn't "hot loading" anymore when I make a change in my project files. (this cause me some trouble, anyhow)
I audited my npm dependencies and had 60 vulnerabilities with 9 high and 2 critical. I thought this should be taken care of.
Now, I tried to install the package that seems to broke things (using npm audit) but to no avail. I still got 31 vulnerabilities even after trying to install a different version of React Script.
Now, if I try to start my app, webpack doesn't compile saying "Cannot find module '@babel/plugin-bugfix-v8-spread-parameters-in-optional-chaining'"
I tried to install the Babel dependencies but every time a new one comes up. I know Babel just recently updated to 7.16 (October 31, 2021). Is this why my problems started?
How should I go about resolving all those dependencies issues? I feel it's a never ending instance of install a new packages that just break another one...
...ANSWER
Answered 2021-Dec-13 at 23:38QUICK UPDATE
I made progress over my dependencies vulnerabilities. The main issue was a package that was interfering with the others. But I didn't clean my packages in a long time so it was impossible to know which one.
Here's my process: (to check what needs to be updated)
QUESTION
I'm trying to implement a global error handling for a React application, which uses Apollo Client 3.4.8.
I'm setting up the App and Apollo like this:
...ANSWER
Answered 2021-Oct-19 at 01:22So, the issue here is that we can't replace a Link in the chain and when doing this:
client.setLink(from([errorLink, client.link]));
we could be adding multiple error handlers.
The solution is to apply again all the links we need + the new error handler we want to set

QUESTION
I'm facing next problem: I have a useQuery hook for getting usersData
GET_USER_INFO useQuery ...ANSWER
Answered 2021-Sep-01 at 17:26You can use the retry link to run the query again.
You should chain your links in a way that the retry link is the most outer link so that you can wait for your error link to fetch the token. Check out the custom strategies, here you could react to a specific status code in the error object or listen to a custom property, that the error link could attach to the operation object. This way you can even prevent a refetch if the token refresh failed (e.g. because the refetch token also timed out).
The links are also all open source so if chaining them doesn't really work for you, you could also develop your own refetch+retry link by combining the code of both links.
