How to add headers to endpoints in RTK-Query Plugin? - graphql-codegen

Trying to follow the rather sparse tutorial on the official page doesn't get me far.
I'm essentially trying to add a certain header based on the params of an api call, but am clueless how to configure the endpoints to do so.

#phry response not working on my case. Checking docs, this make the trick, in my case to resolve a CORS problem:
baseQuery: fetchBaseQuery({
baseUrl: '.....',
prepareHeaders: (headers, { getState }) => {
headers.set('Access-Control-Allow-Origin', '*')
return headers
}
}),

Everything you return from you endpoint's query function will be passed as the first argument to your baseQuery. So if you are using fetchBaseQuery, you need to take a look at that.
Generally, a baseQuery created by fetchBaseQuery takes all the options that a normal fetch call would take - including a headers field.
So you would have something like
myEndpoint: build.query({
query(args) {
return {
url: "foo",
headers: { myHeader: args.blup }
}
}
})
should do the trick.
Generally, besides the "sparse tutorial", there are about 25 more documentation pages when you scroll down - but even then it's difficult to cover everythin, as RTK-Query is rather flexible.
You can read more on fetchBaseQuery in the docs here: https://redux-toolkit.js.org/rtk-query/api/fetchBaseQuery#using-fetchbasequery

You can use prepareHeaders. This worked for me.
createYourEndPoint: builder.mutation({
query: (body) => ({
url: `youEndPoint`,
method: "POST",
body,
prepareHeaders: (headers) => {
headers.set("Content-Type", "multipart/form-data")
return headers
},
}),
invalidatesTags: ["YourEndPointTag"],
}),

You can use prepareHeaders which is the second arg of fetchBaseQuery to customize the header as you need:
`
const baseQuery = fetchBaseQuery({
baseUrl: "",
prepareHeaders: (headers) => {
headers.set("Content-type", "appliation/json"),
headers.set("businessUnit", "EUS,MPS"),
headers.set("auth-token", tokenService.getLocalAccessToken());
return headers;
},
});
`

Cypress intercept call return body as object

I have the follwing code
cy.intercept({
method: "GET",
url: `**/features`
}).as("getFeatures");
cy.wait('#getFeatures').then(({response}) => {
if(response?.statusCode ===200){
expect(response.body.features).to.exist;
expect(response.body.features).to.contain('feature01');
// hier I would like to return the response.body oder response.body.features as an object to interact with the ui based on its value (wether the feature is activated or not)
}
})
Saving the body into a file is not an option because the tests will run in paralel and different tests may access invalid values of feature endpoint
EDIT: because I need this method more than once. I want to return the value of Body as an object the solution I am looking for is like
function visitUrl() : Object {
//intercept
return body
}
You can use alias and save the response body and use it later on.
cy.intercept({
method: 'GET',
url: `**/features`,
}).as('getFeatures')
cy.wait('#getFeatures').then(({response}) => {
if (response?.statusCode === 200) {
expect(response.body.features).to.exist
expect(response.body.features).to.contain('feature01')
cy.wrap(response.body.features).as('responseBodyFeatures')
}
})
cy.get('#responseBodyFeatures').then((features) => {
cy.log(features) //logs the features section from response body
})

How to work with both mocked graphql API and an externally served GraphQL endpoint

I'm hoping to hear some inputs from the experts here.
I'm currently working on NextJS project and my graphql is running on mocked data which is setup in another repo.
and now that the backend is built by other devs were slowly moving away from mocked data to the real ones.
They've given me an endpoint to the backend where I'm supposed to be querying data.
So the goal is to make both mocked graphql data and the real data in backend work side by side at least until we fully removed mocked data.
So far saw 2 ways of doing it, but I was looking for a way where I could still use hooks like useQuery and useMutation
Way #1
require('isomorphic-fetch');
fetch('https://graphql.api....', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ query: `
query {
popularBrands ( storefront:"bax-shop.nl", limit:10, page:1){
totalCount
items{id
logo
name
image
}
}
}`
}),
})
.then(res => res.json())
.then(res => console.log(res.data));
Way #2
const client = new ApolloClient({
uri: 'https://api.spacex.land/graphql/',
cache: new InMemoryCache()
});
async function test () {
const { data: Data } = await client.query({
query: gql`
query GetLaunches {
launchesPast(limit: 10) {
id
mission_name
launch_date_local
launch_site {
site_name_long
}
links {
article_link
video_link
mission_patch
}
rocket {
rocket_name
}
}
}
`
});
console.log(Data)
}
Pseudo code:
Query the real data first
check if its empty, if it is, query the mock data.
If both are empty, then it's really an empty result set.
You can write a wrapper around the hooks you use that does this for you so you don't have to repeat yourself in every component. When you're ready to remove the mocked data you just remove the check for the second. data set.
This is a common technique when switching to a new database.

Mock Graphql server with multiple stubs in Cypress

Problem:
I’m using cypress with angular and apollo graphQl. I’m trying to mock the graph server so I write my tests using custom responses. The issue here is that all graph calls go on a single endpoint and that cypress doesn’t have default full network support yet to distinguish between these calls.
An example scenario would be:
access /accounts/account123
when the api is hit two graph calls are sent out - a query getAccountDetails and another one with getVehicles
Tried:
Using one stub of the graph endpoint per test. Not working as it stubs with the same stub all calls.
Changing the app such that the query is appended 'on the go' to the url where I can intercept it in cypress and therefore have a unique url for each query. Not possible to change the app.
My only bet seems to be intercepting the XHR call and using this, but I don't seem to be able to get it working Tried all options using XHR outlined here but to no luck (it picks only the stub declared last and uses that for all calls) https://github.com/cypress-io/cypress-documentation/issues/122.
The answer from this question uses Fetch and therefore doesn't apply:
Mock specific graphql request in cypress when running e2e tests
Anyone got any ideas?
With cypress 6.0 route and route2 are deprecated, suggesting the use of intercept. As written in the docs (https://docs.cypress.io/api/commands/intercept.html#Aliasing-individual-GraphQL-requests) you can mock the GraphQL requests in this way:
cy.intercept('POST', '/api', (req) => {
if (req.body.operationName === 'operationName') {
req.reply({ fixture: 'mockData.json'});
}
For anyone else hitting this issue, there is a working solution with the new cypress release using cy.route2()
The requests are sent to the server but the responses are stubbed/ altered on return.
Later Edit:
Noticed that the code version below doesn't alter the status code. If you need this, I'd recommend the version I left as a comment below.
Example code:
describe('account details', () => {
it('should display the account details correctly', () => {
cy.route2(graphEndpoint, (req) => {
let body = req.body;
if (body == getAccountDetailsQuery) {
req.reply((res) => {
res.body = getAccountDetailsResponse,
res.status = 200
});
} else if (body == getVehiclesQuery) {
req.reply((res) => {
res.body = getVehiclesResponse,
res.status = 200
});
}
}).as('accountStub');
cy.visit('/accounts/account123').wait('#accountStub');
});
});
Both your query and response should be in string format.
This is the cy command I'm using:
import * as hash from 'object-hash';
Cypress.Commands.add('stubRequest', ({ request, response, alias }) => {
const previousInteceptions = Cypress.config('interceptions');
const expectedKey = hash(
JSON.parse(
JSON.stringify({
query: request.query,
variables: request.variables,
}),
),
);
if (!(previousInteceptions || {})[expectedKey]) {
Cypress.config('interceptions', {
...(previousInteceptions || {}),
[expectedKey]: { alias, response },
});
}
cy.intercept('POST', '/api', (req) => {
const interceptions = Cypress.config('interceptions');
const receivedKey = hash(
JSON.parse(
JSON.stringify({
query: req.body.query,
variables: { ...req.body.variables },
}),
),
);
const match = interceptions[receivedKey];
if (match) {
req.alias = match.alias;
req.reply({ body: match.response });
}
});
});
With that is posible to stub exact request queries and variables:
import { MUTATION_LOGIN } from 'src/services/Auth';
...
cy.stubRequest({
request: {
query: MUTATION_LOGIN,
variables: {
loginInput: { email: 'test#user.com', password: 'test#user.com' },
},
},
response: {
data: {
login: {
accessToken: 'Bearer FakeToken',
user: {
username: 'Fake Username',
email: 'test#user.com',
},
},
},
});
...
Cypress.config is what make it possible, it is kind of a global key/val getter/setter in tests which I'm using to store interceptions with expected requests hash and fake responses
This helped me https://www.autoscripts.net/stubbing-in-cypress/
But I'm not sure where the original source is
A "fix" that I use is to create multiple aliases, with different names, on the same route, with wait on the alias between the different names, as many as requests you have.
I guess you can use aliases as already suggested in Answer by #Luis above like this. This is given in documentation too. Only thing you need to use here is multiple aliases as you have multiple calls and have to manage the sequence between them . Please correct me if i understood you question in other way ??
cy.route({
method: 'POST',
url: 'abc/*',
status: 200.
response: {whatever response is needed in mock }
}).as('mockAPI')
// HERE YOU SHOULD WAIT till the mockAPI is resolved.
cy.wait('#mockAPI')

How can I alias specific GraphQL requests in Cypress?

In Cypress, it is well-documented that you can alias specific network requests, which you can then "wait" on. This is especially helpful if you want to do something in Cypress after a specific network request has fired and finished.
Example below from Cypress documentation:
cy.server()
cy.route('POST', '**/users').as('postUser') // ALIASING OCCURS HERE
cy.visit('/users')
cy.get('#first-name').type('Julius{enter}')
cy.wait('#postUser')
However, since I'm using GraphQL in my app, aliasing no longer becomes a straightforward affair. This is because all GraphQL queries share one endpoint /graphql.
Despite it not being possible to differentiate between different graphQL queries using the url endpoint alone, it is possible to differentiate graphQL queries using operationName (refer to following image).
Having dug through the documentation, there doesn't appear to be a way to alias graphQL endpoints using operationName from the request body. I'm also returning the operationName (yellow arrow) as a custom property in my response header; however, I haven't managed to find a way to use it to alias specific graphQL queries either.
FAILED METHOD 1: This method attempts to use the purple arrow shown in image.
cy.server();
cy.route({
method: 'POST',
url: '/graphql',
onResponse(reqObj) {
if (reqObj.request.body.operationName === 'editIpo') {
cy.wrap('editIpo').as('graphqlEditIpo');
}
},
});
cy.wait('#graphqlEditIpo');
This method doesn't work since the graphqlEditIpo alias is registered at runtime and as such, the error I receive is as follows.
CypressError: cy.wait() could not find a registered alias for: '#graphqlEditIpo'. Available aliases are: 'ipoInitial, graphql'.
FAILED METHOD 2: This method attempts to use the yellow arrow shown in image.
cy.server();
cy.route({
method: 'POST',
url: '/graphql',
headers: {
'operation-name': 'editIpo',
},
}).as('graphql');
cy.wait('graphql');
This method doesn't work because the headers property in the options object for cy.route is actually meant to accept response headers for stubbed routes per the docs. Here, I'm trying to use it to identify my specific graphQL query, which obviously won't work.
Which leads me to my question: How can I alias specific graphQL queries/mutations in Cypress? Have I missed something?
The intercept API introduced in 6.0.0 supports this via the request handler function. I used it in my code like so:
cy.intercept('POST', '/graphql', req => {
if (req.body.operationName === 'queryName') {
req.alias = 'queryName';
} else if (req.body.operationName === 'mutationName') {
req.alias = 'mutationName';
} else if (...) {
...
}
});
Where queryName and mutationName are the names of your GQL operations. You can add an additional condition for each request that you would like to alias. You can then wait for them like so:
// Wait on single request
cy.wait('#mutationName');
// Wait on multiple requests.
// Useful if several requests are fired at once, for example on page load.
cy.wait(['#queryName, #mutationName',...]);
The docs have a similar example here: https://docs.cypress.io/api/commands/intercept.html#Aliasing-individual-requests.
This works for me!
Cypress.Commands.add('waitForGraph', operationName => {
const GRAPH_URL = '/api/v2/graph/';
cy.route('POST', GRAPH_URL).as("graphqlRequest");
//This will capture every request
cy.wait('#graphqlRequest').then(({ request }) => {
// If the captured request doesn't match the operation name of your query
// it will wait again for the next one until it gets matched.
if (request.body.operationName !== operationName) {
return cy.waitForGraph(operationName)
}
})
})
Just remember to write your queries with unique names as posible, because the operation name relies on it.
If 'waiting' and not 'aliasing' in itself is the main purpose, the easiest way to do this, as I've encountered thus far, is by aliasing the general graphql requests and then making a recursive function call to 'wait' targeting the newly created alias until you find the specific graphql operation you were looking for.
e.g.
Cypress.Commands.add('waitFor', operationName => {
cy.wait('#graphqlRequest').then(({ request }) => {
if (request.body.operationName !== operationName) {
return cy.waitFor(operationName)
}
})
})
This of course have its caveats and may or may not work in your context. But it works for us.
I hope Cypress enables this in a less hacky way in the future.
PS. I want to give credit to where I got the inspiration to this from, but it seemt to be lost in cyberspace.
Since I was having the same issue and I did not find a real solution for this problem I combined different options and created a workaround that solves my problem. Hopefully this can help someone else too.
I do not really 'wait' for the request to be happen but I catch them all, based on **/graphql url and match the operationName in the request. On a match a function will be executed with the data as parameter. In this function the tests can be defined.
graphQLResponse.js
export const onGraphQLResponse = (resolvers, args) => {
resolvers.forEach((n) => {
const operationName = Object.keys(n).shift();
const nextFn = n[operationName];
if (args.request.body.operationName === operationName) {
handleGraphQLResponse(nextFn)(args.response)(operationName);
}
});
};
const handleGraphQLResponse = (next) => {
return (response) => {
const responseBody = Cypress._.get(response, "body");
return async (alias) => {
await Cypress.Blob.blobToBase64String(responseBody)
.then((blobResponse) => atob(blobResponse))
.then((jsonString) => JSON.parse(jsonString))
.then((jsonResponse) => {
Cypress.log({
name: "wait blob",
displayName: `Wait ${alias}`,
consoleProps: () => {
return jsonResponse.data;
}
}).end();
return jsonResponse.data;
})
.then((data) => {
next(data);
});
};
};
};
In a test file
Bind an array with objects where the key is the operationName and the value is the resolve function.
import { onGraphQLResponse } from "./util/graphQLResponse";
describe("Foo and Bar", function() {
it("Should be able to test GraphQL response data", () => {
cy.server();
cy.route({
method: "POST",
url: "**/graphql",
onResponse: onGraphQLResponse.bind(null, [
{"some operationName": testResponse},
{"some other operationName": testOtherResponse}
])
}).as("graphql");
cy.visit("");
function testResponse(result) {
const foo = result.foo;
expect(foo.label).to.equal("Foo label");
}
function testOtherResponse(result) {
const bar = result.bar;
expect(bar.label).to.equal("Bar label");
}
});
}

Used the blob command from glebbahmutov.com
This is what you're looking for (New in Cypress 5.6.0):
cy.route2('POST', '/graphql', (req) => {
if (req.body.includes('operationName')) {
req.alias = 'gqlMutation'
}
})
// assert that a matching request has been made
cy.wait('#gqlMutation')
Documentation:
https://docs.cypress.io/api/commands/route2.html#Waiting-on-a-request
I hope that this helps!
I used some of these code examples but had to change it slightly to add the onRequest param to the cy.route and also add the date.Now (could add any auto incrementer, open to other solutions on this) to allow multiple calls to the same GraphQL operation name in the same test. Thanks for pointing me in the right direction!
Cypress.Commands.add('waitForGraph', (operationName) => {
const now = Date.now()
let operationNameFromRequest
cy.route({
method: 'POST',
url: '**graphql',
onRequest: (xhr) => {
operationNameFromRequest = xhr.request.body.operationName
},
}).as(`graphqlRequest${now}`)
//This will capture every request
cy.wait(`#graphqlRequest${now}`).then(({ xhr }) => {
// If the captured request doesn't match the operation name of your query
// it will wait again for the next one until it gets matched.
if (operationNameFromRequest !== operationName) {
return cy.waitForGraph(operationName)
}
})
})
to use:
cy.waitForGraph('QueryAllOrganizations').then((xhr) => { ...
This is how I managed to differentiate each GraphQL request. We use cypress-cucumber-preprocessor so we have a common.js file in /cypress/integration/common/ where we can call a before and beforeEach hook which are called before any feature file.
I tried the solutions here, but couldn't come up with something stable since, in our application, many GraphQL requests are triggered at the same time for some actions.
I ended up storing every GraphQL requests in a global object called graphql_accumulator with a timestamp for each occurence.
It was then easier to manage individual request with cypress command should.
common.js:
beforeEach(() => {
for (const query in graphql_accumulator) {
delete graphql_accumulator[query];
}
cy.server();
cy.route({
method: 'POST',
url: '**/graphql',
onResponse(xhr) {
const queryName = xhr.requestBody.get('query').trim().split(/[({ ]/)[1];
if (!(queryName in graphql_accumulator)) graphql_accumulator[queryName] = [];
graphql_accumulator[queryName].push({timeStamp: nowStamp('HHmmssSS'), data: xhr.responseBody.data})
}
});
});
I have to extract the queryName from the FormData since we don't have (yet) the key operationName in the request header, but this would be where you would use this key.
commands.js
Cypress.Commands.add('waitGraphQL', {prevSubject:false}, (queryName) => {
Cypress.log({
displayName: 'wait gql',
consoleProps() {
return {
'graphQL Accumulator': graphql_accumulator
}
}
});
const timeMark = nowStamp('HHmmssSS');
cy.wrap(graphql_accumulator, {log:false}).should('have.property', queryName)
.and("satisfy", responses => responses.some(response => response['timeStamp'] >= timeMark));
});
It's also important to allow cypress to manage GraphQL requests by adding these settings in /cypress/support/index.js:
Cypress.on('window:before:load', win => {
// unfilters incoming GraphQL requests in cypress so we can see them in the UI
// and track them with cy.server; cy.route
win.fetch = null;
win.Blob = null; // Avoid Blob format for GraphQL responses
});
I use it like this:
cy.waitGraphQL('QueryChannelConfigs');
cy.get(button_edit_market).click();
cy.waitGraphQL will wait for the latest target request, the one that will be stored after the call.
Hope this helps.
Somewhere else this method was suggested.
Btw it all becomes a bit easier once you migrate to Cypress v5.x and make use of the new route (route2) method.
Our use case involved multiple GraphQL calls on one page. We had to use a modified version of the responses from above:
Cypress.Commands.add('createGql', operation => {
cy.route({
method: 'POST',
url: '**/graphql',
}).as(operation);
});
Cypress.Commands.add('waitForGql', (operation, nextOperation) => {
cy.wait(`#${operation}`).then(({ request }) => {
if (request.body.operationName !== operation) {
return cy.waitForGql(operation);
}
cy.route({
method: 'POST',
url: '**/graphql',
}).as(nextOperation || 'gqlRequest');
});
});
The issue is that ALL GraphQL requests share the same URL, so once you create a cy.route() for one GraphQL query, Cypress will match all the following GraphQL queries to that. After it matches, we set cy.route() to just a default label of gqlRequest or the next query.
Our test:
cy.get(someSelector)
.should('be.visible')
.type(someText)
.createGql('gqlOperation1')
.waitForGql('gqlOperation1', 'gqlOperation2') // Create next cy.route() for the next query, or it won't match
.get(someSelector2)
.should('be.visible')
.click();
cy.waitForGql('gqlOperation2')
.get(someSelector3)
.should('be.visible')
.click();

Use Apollo Client or Isomorphic Fetch with GraphiQL

I am trying to integrate the GraphiQL IDE into my website and am wondering if I can get some advice on whether I would be best using the Apollo Client that the rest of the site uses or using Isomorphic Fetch as recommended in the documentation.
If I use the Apollo Client then I only have one connection to worry about and don't have to think about ensuring authentication is correct but the code is more complex.
I have this code working for the fetcher function, but so far it only works with queries and to my understanding would need a fair amount of work to work with mutations as well.
graphQlFetcher = (params) => {
return this.props.client.query({
query: gql`
${params.query}
`
}).then(function(result) {
return result;
});
}
Alternatively there is the isomorphic fetch approach, but for this to work I need to get the authentication token first and I am not good enough with promises to make this work. Not working code:
import { Auth } from 'aws-amplify';
getToken = async () => {
const session = await Auth.currentSession();
return session.accessToken.jwtToken;
}
graphQLFetcher = (graphQLParams) => {
return getToken().then(function(token) {
fetch(window.location.origin + '/graphql', {
method: 'post',
headers: {
'Content-Type': 'application/json',
"Authorization": token
},
body: JSON.stringify(graphQLParams),
}).then(response => response.json());
})
}
Appreciate that there are two possible ways to solve this problem and that it is as much a design question as a technical one but hoping that someone can help me out.
The first one is fine, but you have some excess syntax on there. This is what I use:
params => client.query({ ...params, query: gql(params.query) });
