Any advice or links would be very appreciated! Thanks for contributing an answer to Stack Overflow! Have a question about this project? If you check on the console the type of window it returns object. Addendum: I've actually just gone ahead and refactored the Session class to use fetch now. Since the PRs above aren't merged yet, I am not sure there's a solution other than using the REST API directly over the SDK. , Hello @kiwicopple it's not working for me, i do it createClient('..','..',{fetch:fetch}) but it still doesn't work, Cloudflare workers shows Invalid invocation. In the past I succeeded to upload the project to heroku, and it works.Oftentimes it can suddenly stop working and and an XMLHttpRequest error appears. I have a server using node and express. (using fetch: (args) => fetch(args), didn't try the other syntaxes yet.). Sign in Interesting! privacy statement. Stack Overflow for Teams is moving to its own domain! Thanks to your bug report I think I have a fix for this rolled out now! An old thread, but I just came across https://github.com/Janpot/next-rpc which looks really awesome! @PH4NTOMiki that's probably unclear documentation on my part, I believe if you directly pass the native fetch function as the custom fetch, JavaScript will treat this as an "illegal invocation" as it tries to execute a native method in the context of the Supabase options argument rather than in the global context it was attached to. Thanks. In the generated code you can clearly see the browserPonyfill being inlined instead of node-fetch. Luckily for us, there are three easy solutions to using window in our NextJS apps. You can either use the useEffect hook or check if document exists (i.e. How to check a not-defined variable in JavaScript, Open a URL in a new tab (and not a new window), JavaScript check if variable exists (is defined/initialized), Sending multipart/formdata with jQuery.ajax. i tried grpc-web i got an error stating ReferenceError: XMLHttpRequest is not defined it did not work, Uncaught ReferenceError: is not defined javascript method; Uncaught ReferenceError: jQuery is not defined in django; Uncaught ReferenceError: $ is not defined chessboardjs; jQuery.Deferred exception: e is not defined ReferenceError: e is not defined; html Uncaught ReferenceError: is not defined; index:203 Uncaught ReferenceError: $ is not defined The problem is that it only reads dependencies once: https://github.com/vitejs/vite/blob/344d77e9735bc907b9383ad729afb0a8daa2af5f/packages/vite/src/node/plugins/resolve.ts#L466. To run with Vercel, do we need to setup docker & custom server? Click on a button to fetch the endpoint and observe the cloud functions logs on Vercel. Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, The browser should certainly have XMLHttpRequest, but it looks like you spelled it wrong (or used upper case letters where you shouldn't). Nice article on Object.observe() on HTML5 rocks. Back to the file, I get another error: These modules were not found: The text was updated successfully, but these errors were encountered: I ran into the same problem when i switched over my project to use yarnI removed the now-logs dependency, which includes the xmlhttprequest-ssl package. All new C# 6 and beyond features and their status. I'm building the client app. We only access the window object when we . I have trouble getting the server side code to work. PR: fauna/faunadb-js#214. This causes dev mode to break, so only add node deps to noExternal when process.env.NODE_ENV = "production. That's why you need noExternal to include all node dependencies otherwise you get errors during deployment. Maybe something Heroku specific is going on. Check to see if the window object is defined. It uses NodeJS to render your application and window is not defined in NodeJS. I've opened several PRs that allow specifying a custom fetch implementation as an option - ideally I think cross-fetch should support environments like Cloudflare Workers given its use in the ecosystem, but a custom fetch option enables a workaround today, gives flexibility for future environments (e.g. make sure the code that depends on document runs in the browser, not Node. If no fetch is provided, cross-fetch is used. Next js executes this code on the server side and that's why the error is thrown. and I'm considering if it's worth the hassle of supporting. Fix: new XMLHttpRequest() Uncaught ReferenceError: request is not defined. is there a way to get grpc working in next js. Something strange happened to me: suddenly I get an error from the session component, "XMLHttpRequest is not defined". Essentially, they added an extra config argument that allows users to opt-out of cross-fetch by passing in a custom fetch function. Edit: updated config to correctly reproduce error. There are three ways to fix that: 1. You can pass a custom function or bind the fetch function to work around that issue. https://github.com/improbable-eng/grpc-web, https://github.com/SabariVig/fullstack-grpc. Supabase is working marvelously and took exactly one evening to actually get working. I can't thank you enough! rev2022.11.3.43005. It shouldn't be calling XMLHttpRequest on the server ever. Was this translation helpful? How can we create psychedelic experiences for healthy people without drugs? Even using Node 18 didn't help. the strange thing is that when a user is logging and have a token in the local storage, the app crashes every some days and the error in the console is "XMLHttpRequest is not defined".

Serverless deployments require bundling of node_modules. On index.html, there's a button, with functionality associated with the onclick event that's defined in main.js. The type of request is dictated by the optional async argument (the third argument) that is set on the XMLHttpRequest.open() method. I do want to refactor this code, and I did get a pull request for that, but there were some issue with the PR and I had to revert the change unfortunately. It's probably easiest to configure email authentication first, just to check it's all working. It is now read-only. So far, so good. You signed in with another tab or window. ReferenceError: self is not defined It looks like FaunaDB solved this. I tried building Vite locally and it doesn't appear to make a difference. Hey @jcs224 - it looks like the linked issue was resolved. The "XMLHttpRequest is not defined" error occurs for 2 main reasons: Trying to use the XMLHttpRequest in a Node.js application (on the server side). Honestly, I don't even know quite what to search for to try and find an explanation for this set of issues. Strongly suspect this is lquixada/cross-fetch#78 "Cross-fetch is not usable in service workers" in disguise. it's possible to replace the XMLHttpRequest with fetch or axios? 2022 Moderator Election Q&A Question Collection. No Comments on Using react-papaparse in the Next.js getStaticProps - XMLHttpRequest is not defined; I am trying to use papaparse inside my Next.js page. https://github.com/Pixselve/supabase-sveltekit-endpoints, https://github.com/supabase/supabase/tree/master/examples/with-cloudflare-workers, Vite resolves import with browser field during SSR, Isomorphic libraries use wrong entry point when building SSR bundle, Get the proper global object depending on environment to check for existing fetch, feat: allow providing custom fetch implementation, But even if it did resolve correctly, Vite only does one pass over each dependency and then caches it. After running npm update to update packages and re-deploying, it now works as expected in production on Cloudflare Pages! at /Users/sam/just-start/src/routes/submitform.js:7:65 Check out https://github.com/SabariVig/fullstack-grpc if you need any reference. I've been trying to get this working over the weekend, my package.json is: Deploying this configuration to vercel serverless produces the "XMLHTTPRequest is not defined" error in production. In that case, you could try this: https://github.com/supabase/supabase/tree/master/examples/with-cloudflare-workers. It could happen when the client had an existing session, but it had expired on the server and then the page was reloaded on the client (e.g. Solution 1. Setting up Jest (with the Rust Compiler) Since the release of Next.js 12, Next.js now has built-in configuration for Jest. module.exports = config; This example configuration will run Jest in the root directory as well as in every folder in the examples directory. "XMLHttpRequest is not defined" on sveltekit endpoints when deployed on Vercel. If this argument is true or not specified, the XMLHttpRequest is processed asynchronously, otherwise the process is handled synchronously. at /Users/sam/just-start/src/routes/submitform.js:7:65 self is not defined When delete the connect.sid cookie is starts working again. any ideas? I'm getting a similar issue adding const supabase = createClient('', '', {fetch: fetch.bind(self)}) still results in the XMLHTTPrequest error when deployed on Cloudflare pages. To solve the error, install and import the form-data npm package. Why does the sentence uses a question form, but it is put a period in the end? My understanding is that the browser (Chrome/V8) and node are separate JavaScript environments. What is the !! Employer made me redundant, then retracted the notice after realising that I'm about to start on a new project, Replacing outdoor electrical box at end of conduit, Water leaving the house when water cut off. Things like XMlHttpRequest, which are defined in node, are not defined in V8. When I added global.XMLHttpRequest = require ("xmlhttprequest"); But when tried I get ReferenceError: XMLHttpRequest as mentioned above. I do want to refactor this code, and I did get a pull request for that, but there were some issue with the PR and I had to revert the change unfortunately. I'm finding the docs confusing. To solve the "XMLHttpRequest is not defined" error, install an alternative package like node-fetch or axios, which are more recent and more user-friendly ways to. The alert method is a method on the window object, which is only available in the browser. You can't have the same package resolve to a different entry point for SSR unless you remove. But when the button is clicked, I get a console message in the browser reading "XMLHttpRequest is not defined." My understanding is that the browser (Chrome/V8) and node are separate JavaScript environments. The reason it uses XMLHttpRequest rather than fetch is interesting, it's actually to do with having HTTP Only cookies (that can't be read in JavaScript) while still supporting universal rendering. Note you will need to configure authentication via env vars. A request made via XMLHttpRequest can fetch the data in one of two ways, asynchronously or synchronously. You signed in with another tab or window. Could be - we already had to do a bunch of work to make Vite work: Is this still causing problems on the latest supabase-js? When delete the connect.sid cookie is starts working again. sbutler-gh/just-start@c32ecef/package-lock.json#L325-L326. You need that onethe ssl version: https://www.npmjs.com/package/xmlhttprequest-ssl Then it will fail with "ReferenceError: document is not defined": Because in the Node.js world, document is not defined, document is only available in browsers. Because typeof won't try to evaluate "window", it will only try to get its type, in our case in Node.js . It does this to provide a "best practice" example but actually it complicates authentication significantly, Issue: fauna/faunadb-js#207 DatePickerComponent * * @return void */ plugin ReferenceError : window is not defined The easiest way to resolve this is to use an if to avoid running those lines of . Does it also solve this issue? To set up Jest, install jest, jest-environment-jsdom, @testing-library/react, @testing-library/jest-dom: Create a jest.config.js file in your project's root directory and add the following: Thanks for the added detail. I will see what the browser support for fetch with credentials: 'same-origin' is like to see if it works with HTTP Only cookies in browsers now, and if so trying and merge that pull request back in - the code isn't that complex, but fetch is a terser and easier to read and debug. Back to the file, I get another error: These modules were not found: The text was updated successfully, but these errors were encountered: I ran into the same problem when i switched over my project to use yarnI removed the now-logs dependency, which includes the xmlhttprequest-ssl package. The text was updated successfully, but these errors were encountered: Thanks for reporting this one @Pixselve - i'll transfer it to the JS library repo. @kiwicopple, would this be straightforward to implement? This ensures that our code only runs on the client-side. Most of the complexity is caused by the code supporting HTTP Only cookies. You don't need to configure a user database just for testing, but if you don't the database will just be erased every time you restart the service. global.XMLHttpRequest = require ('xhr2'); Share Follow answered Dec 6, 2019 at 13:39 Rok Povsic 4,436 5 36 49 Add a comment Your Answer with refresh, or by visiting the site again after a period of being idle). That is a simple check to see if the window object is defined. Now you may ask, why it should run on Node.js? I see now that when i remove the connect.sid cookie the app back to normal. Thank you all for your hard work. The index.html file is served by express to the client when they access the website. Follow. I note that the PR mentioned above has already been merged. Vite creates two bundles, a server bundle "functions/node/render/server/app.mjs" and a client bundle "static/_app/*". This is because, Next.js is server-side rendered, and it runs the component code in the server, sends the HTML to the browser, and the HTML gets hydrated in the browser. Thank you SO MUCH @jacobwgillespie ! Next.js is compiled/built on Node.js runtime and Node.js does not have the the window object. Thanks to a very impressive series of PRs from @jacobwgillespie , this now has a workaround, https://github.com/supabase/supabase-js/releases/tag/v1.27.0, after upgrading to v1.27.0 you can use a custom fetch implementation, Jacob - if you send your details (and tshirt size) to swag@supabase.io we will send you a nice package , Hello @kiwicopple it's not working for me, i do it createClient('..','..',{fetch:fetch}) not the older xmlhttprequest package. Is there any examples where i can refer or any blog post doing the same Vincent Voyer. I haven't been able to find a source that digs into how I can serve up an HTML + javascript page that allows the user to send AJAX requests back to the server that addresses this issue. It does this to provide a "best practice" example but actually it complicates authentication significantly, It would probably also work with fetch: (args) => fetch(args). You can have an unlimited amount of projects running in the same Jest instance. Check to see if the window object is defined; Use the window object inside React useEffect hook or the componentDidMount lifecycle method in class components; Use globalThis property to access the window; 1. With the xhr2 library you can globally overwrite XMLHttpRequest from your JS code. tcolorbox newtcblisting "! FYI this also happens when supabase-js is used within NextJS 12 middleware. You need that onethe ssl version: https://www.npmjs.com/package/xmlhttprequest-ssl I.e. xmlhttprequest javascript javascript by Usher Godwin on Nov 29 2021 Comment 4 xxxxxxxxxx 1 let xhr = new XMLHttpRequest(); 2 xhr.onreadystatechange = function() { 3 if(this.readyState === 4 && this.status === 200) 4 { 5 document.getElementById('response-div').innerHTML = this.responseText 6 } 7 } 8 //get request with params 9 Something strange happened to me: suddenly I get an error from the session component, "XMLHttpRequest is not defined". Addendum: I've actually just gone ahead and refactored the Session class to use fetch now. @sbutler-gh I think your repo isn't actually using the up-to-date version of @supabase/supabase-js, see here: https://github.com/sbutler-gh/just-start/blob/c32ecef9d35bfbcb67f187f6725b66986a288b0a/package-lock.json#L325-L326. Is there any examples where i can refer or any blog post doing the same, You're taking about https://github.com/improbable-eng/grpc-web. The issue seemed to be that Heroku didn't know to run "next build" before running "next start" (required on production for Next.js apps). By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. So my hacky workaround at the moment is to force disable the browser entry point during SSR module generation, and to disable module caching. I think I've gotten to the bottom of this. How many characters/pages could WordStar hold on a typical CP/M machine? Does squeezing out liquid from shredded potatoes significantly reduce cook time? got it done after an hour or two of npm misadventures. First off, cross-fetch always resolves to the browser entry point. supabase-js (depends on the other three PRs). Using the client for auth or for querying the database in a sveltekit endpoint throw an error : I made a repository exposing the issue : https://github.com/Pixselve/supabase-sveltekit-endpoints My thoughts after trying to port a Shopify store from NextJS to Shopify Hydrogen. It should be. I will see what the browser support for fetch with credentials: 'same-origin' is like to see if it works with HTTP Only cookies in browsers now, and if so trying and merge that pull request back in - the code isn't that complex, but fetch is a terser and easier to read and debug. It could happen when the client had an existing session, but it had expired on the server and then the page was reloaded on the client (e.g. No tutorial I find on how to use AJAX mentions this as an issue. This is confusing to me. Making statements based on opinion; back them up with references or personal experience. But when tried I get ReferenceError: XMLHttpRequest as mentioned above.

What exactly makes a black hole STAY a black hole? ones that don't yet exist or are more esoteric), and allows you to provide a mocked fetch for testing or otherwise customize fetch based on your specific needs. I did a review of all calls to XMLHttpRequest in the project (they are all in components/session.js) and there was one place where XMLHttpRequest could accidentally be called while running on the server (which it should never be). Most of the complexity is caused by the code supporting HTTP Only cookies. Vite creates two bundles, a server bundle "functions/node/render/server/app.mjs" and a client bundle "static/_app/*". Well occasionally send you account related emails. I'm going to re-open this and see if I can replicate the problem. The following example shows an image component that is the same width as the viewport. https://www.npmjs.com/package/xmlhttprequest-ssl, child_process in ./node_modules/xmlhttprequest/lib/XMLHttpRequest.js, fs in ./node_modules/xmlhttprequest/lib/XMLHttpRequest.js.
