kandi X-RAY | mercure Summary

mercure is a Go library typically used in Networking, Websocket applications. mercure has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has medium support. You can download it from GitHub.

Mercure is a protocol allowing to push data updates to web browsers and other HTTP clients in a convenient, fast, reliable and battery-efficient way. It is especially useful to publish async and real-time updates of resources served through web APIs, to reactive web and mobile apps. The protocol has been published as an Internet Draft that is maintained in this repository. A reference, production-grade, implementation of a Mercure hub (the server) is also available in this repository. It's a free software (AGPL) written in Go. It is provided along with a library that can be used in any Go application to implement the Mercure protocol directly (without a hub) and an official Docker image. In addition, a managed and high-scalability version of the Mercure.rocks hub is available on Mercure.rocks.

QUESTION

Symfony 5.4 - How am i supposed to properly start mercure using symfony

Asked 2022-Apr-01 at 11:50

I installed mercure using the following command as stated in the documentation:

composer require mercure

After that, i'm supposed to start the mercure server and here is the issue: how?

Symfony's documentation doesn't state that.
Mercure's documentation also doesn't state anything about it, especially using a config file generated in /config/packages/mercure.yaml.

What i've found is that i need to download a separate binary (for my specific platform) and then i'm supposed to start the server from Powershell using the following:

.\/bin/mercure run

However, if i try to pass -envfile ".env", then it doesn't even try to use any of the variables inside.
On top of that, it doesn't seem to be using any environment variables at all, even ones i've defined in cmd.

There are other things like how do i allow CORS, as there isn't something i can change in my config file, it isn't an argument i can pass to the binary and i can't add it as an environment variable.

if i ever try to subscribe to the event (which is done on port 2019 cause of the previous issues), 404 and CORS is returned.

also this is what i get with just .\/bin/mercure run:

My .env:

Right now i'm wondering how am i supposed to use mercure, i've looked at a couple videos for symfony 5.4 and they basically either are on linux and it somehow work for them OR It's marked as outdated cause of configs changes, syntax changes and others...

The documentation also doesn't help at all in that regard which kind of make me regret trying to use mercure.

EDIT:

I was told to try fiddling with Caddy configs, but it doesn't seem like mercure is trying to use those either, even tried specifying the config with -config.

Result:

Port not set to 3000
No allow_cors header

I will give you an example of mercure running over windows without use of Docker, sorry for my english ok?!!

I will start from an installation of symfony 5.4 with a SSL virtual host: https://myshop.local and MercureBundle.

The goal is to notify for example, to all authenticated users when a new product enter on a shop stock.

First: the mercure hub and your site must run over the same domain or subdomain, in other case isn't possible to share the auth cookie; so our mercure hub will run on https://myshop.local:3000 (the same domain, but another port, check your firewall)

Second: It's neccesary to set the appropiates environment variables, so in your .env.local:

Symfony Mercure "Failed to send an update"

Asked 2022-Feb-14 at 15:18

I am having an issue sending updates to the Caddy-based Mercure Hub with both the Symfony Mercure\HubInterface and the "pure" PHP example.

When attempting to publish an update (following the official Symfony/Mercure tutorial), I get the error "Failed to send an update", with the TransportException:

"SSL certificate problem: unable to get local issuer certificate for "https://localhost/.well-known/mercure".

When trying to publish with the "pure" PHP example: https://github.com/dunglas/mercure/blob/main/examples/publish/php.php

I get the error:

"Warning: file_get_contents(https://localhost/.well-known/mercure): Failed to open stream: operation failed in /"path"/test.php on line 13"

When printing the enum value directly, as you have found it prints information along with it. If you just want the name of the enum, e.g. "MARS", try using the name method, which returns a string of name.

Example: System.out.println(Dept.get().name());

Why I can find/save from command line but not in my Symfony app?

Asked 2021-Oct-17 at 09:39

For my personal development, I try using this repo https://github.com/dunglas/symfony-docker as Docker base to create a PHP 8/Symfony 5 environnement.

I could launch my App on https://localhost, updating my project is reflected on browser. But I got a weird thing with Doctrine. Actually, I could update my database schema using Symfony command bin/console doctrine:schema:update --force, using Doctrine Migrations or insert data using command too. But, when I try to find/save data within my Symfony app, there is no result when I find and no data insert on create/update.

Here is my docker-compose.yml (almost same as repo, only database > volumes change):
