kandi X-RAY | fetch Summary

fetch is a JavaScript library typically used in Programming Style, Reactive Programming, Symfony applications. fetch has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can install using 'npm i whatwg-fetch-strict' or download it from GitHub, npm.

The fetch() function is a Promise-based mechanism for programmatically making web requests in the browser. This project is a polyfill that implements a subset of the standard Fetch specification, enough to make fetch a viable replacement for most uses of XMLHttpRequest in traditional web applications.

It is because of the node-fetch package. As recent versions of this package only support ESM, you have to downgrade it to an older version node-fetch@2.6.1 or lower.

npm i node-fetch@2.6.1

This should solve the issue.

Fixing git HTTPS Error: "bad key length" on macOS 12

Asked 2022-Mar-29 at 17:34

I am using a company-hosted (Bitbucket) git repository that is accessible via HTTPS. Accessing it (e.g. git fetch) worked using macOS 11 (Big Sur), but broke after an update to macOS 12 Monterey. *

After the update of macOS to 12 Monterey my previous git setup broke. Now I am getting the following error message:

ANSWER

Answered 2021-Nov-02 at 07:12

Unfortunately I can't provide you with a fix, but I've found a workaround for that exact same problem (company-hosted bitbucket resulting in exact same error). I also don't know exactly why the problem occurs, but my best guess would be that the libressl library shipped with Monterey has some sort of problem with specific (?TLSv1.3) certs. This guess is because the brew-installed openssl v1.1 and v3 don't throw that error when executed with /opt/homebrew/opt/openssl/bin/openssl s_client -connect ...:443

To get around that error, I've built git from source built against different openssl and curl implementations:

install autoconf, openssl and curl with brew (I think you can select the openssl lib you like, i.e. v1.1 or v3, I chose v3)
clone git version you like, i.e. git clone --branch v2.33.1 https://github.com/git/git.git
cd git
make configure (that is why autoconf is needed)
execute LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib -L/opt/homebrew/opt/curl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include -I/opt/homebrew/opt/curl/include" ./configure --prefix=$HOME/git (here LDFLAGS and CPPFLAGS include the libs git will be built against, the right flags are emitted by brew on install success of curl and openssl; --prefix is the install directory of git, defaults to /usr/local but can be changed)
make install
ensure to add the install directory's subfolder /bin to the front of your $PATH to "override" the default git shipped by Monterey
restart terminal
check that git version shows the new version

This should help for now, but as I already said, this is only a workaround, hopefully Apple fixes their libressl fork ASAP.

Use ESM syntax, also use one of these methods before running the file.

specify "type":"module" in package.json
Or use this flag --input-type=module when running the file
Or use .mjs file extension

Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391

You need to wait until Apache Kafka 3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

From the node-fetch package readme:

node-fetch is an ESM-only module - you are not able to import it with require. We recommend you stay on v2 which is built with CommonJS unless you use ESM yourself. We will continue to publish critical bug fixes for it.

If you want to require it, then downgrade to v2.

The other option you have is to use async import('node-fetch').then(...)

Chrome 98 Private Network Access problem w/ disabled web security: Request had no target IP address space, yet the resource is in address space local

Asked 2022-Feb-25 at 16:03

We have a test environment on a public site. There we use --disable-web-security flag on chrome for the testers to bypass CORS errors for public service calls during manual test phase. And also we have localhost requests on the agent machine. However today with Chrome 98 update we started struggling with the network requests targeting localhost.

The error we get is for the localhost requests from a public site:
Access to XMLHttpRequest at 'https://localhost:3030/static/first.qjson' from origin 'https://....com' has been blocked by CORS policy: Request had no target IP address space, yet the resource is in address space `local`.

The site on localhost is configured to return Access-Control-Allow-* CORS headers including "Access-Control-Allow-Private-Network: true".

And also I do not see any preflight request. Just one GET request with CORS error on it.

We suspect this might be a side effect caused when you disable web security by --disable-web-security. It might be preventing obtaining of the target IP address space. Our assumption is based on the CORS preflight section on https://wicg.github.io/private-network-access/

3.1.2. CORS preflight
The HTTP fetch algorithm should be adjusted to ensure that a preflight is triggered for all private network requests initiated from secure contexts.

The main issue here is again that the response’s IP address space is not known until a connection is obtained in HTTP-network fetch, which is layered under CORS-preflight fetch.

So does anyone know any workaround for Private Network Access with --disable-web-security flag ? Or maybe we are missing something. Thanks for the help.

Below Steps can help to solve issue in chrome 98, for other browser like edge you need to do similar like chrome.

For MAC

Requestly with chrome version 98. You need to follow following steps :- Run this command on terminal

defaults write com.google.Chrome InsecurePrivateNetworkRequestsAllowed -bool true
Restart your Browser, Not work then restart your machine

For WINDOWS

Run 'regedit' to open windows registry (If permission issue came then run that command with Admin command prompt)
Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
Create new DWORD value with "InsecurePrivateNetworkRequestsAllowed" Name
Change Value to "1"
Restart your Browser

Here is my simple query:

ANSWER

Answered 2022-Jan-30 at 12:24

You can use Keyset Pagination for this. It's far more efficient than using Rowset Pagination (paging by row number).

In Rowset Pagination, all previous rows must be read, before being able to read the next page. Whereas in Keyset Pagination, the server can jump immediately to the correct place in the index, so no extra rows are read that do not need to be.

In this type of pagination, you cannot jump to a specific page number. You jump to a specific key and read from there. For this to perform well, you need to have a unique index on that key, which includes any other columns you need to query.

One big benefit, apart from the obvious efficiency gain, is avoiding the "missing row" problem when paginating, caused by rows being removed from previously read pages. This does not happen when paginating by key, because the key does not change.

Here is an example:

Let us assume you have a table called TableName with an index on Id, and you want to start at the latest Id value and work backwards.

Install fetch

As an alternative to using npm, you can obtain fetch.umd.js from the Releases section. The UMD distribution is compatible with AMD and CommonJS module loaders, as well as loading directly into a page via <script> tag. You will also need a Promise polyfill for older browsers. We recommend taylorhakes/promise-polyfill for its small size and Promises/A+ compatibility.

Support

Note: modern browsers such as Chrome, Firefox, Microsoft Edge, and Safari contain native implementations of window.fetch, therefore the code from this polyfill doesn't have any effect on those browsers. If you believe you've encountered an error with how window.fetch is implemented in any of these browsers, you should file an issue with that browser vendor instead of this project.
