Web Extract Worker, a service with text-to-image worker AI models!

peter279k — Fri, 12 Apr 2024 17:44:36 +0000

What I Built

In our web service, we can fill the prompt and generate image with one of the text-to-image worker AI model randomly.

The user scenario image is as folows:

Demo

Our front-end worker is deployed at the Cloudflare Pages.

Try out our web service!

Firstly, open the web page and browse the above link:

Input the corgi to be the prompt and click "Generate" button:

After waiting for about whiles, it will present generated image:

You're done for our web service tutorial now!

My Code

Our source code is available here:

Web Extract Worker

Introduction

The web-based extract text to image worker :).

Installation

Firstly, clone or fork this repository.
Second, please refer the Cloudflare Pages Docs to complete the front-end page deployment.

View on GitHub

And our techniques are as follows:

Front-end: The index.html is the main page to let users input their prompts and see generated image.
Back-end: The extract.php is the main PHP program to handle user prompt and respond generated image.

Journey

We used these following models and the PHP program will choose them randomly when retrieving user prompts:

Image-to-text: @cf/lykon/dreamshaper-8-lcm
Image-to-text: @cf/stabilityai/stable-diffusion-xl-base-1.0
Image-to-text: @cf/bytedance/stable-diffusion-xl-lightning

It's the dead simple for PHP developers to learn how to use the native PHP codes to develop a extract text to image service via the Cloudflare worker AI models :).

Background

My aunt likes to watch the Japanese music video and she wants to use the video to make her own music video.

However, many on-line YouTube video downloader websites are not convenient for people because they contain some advertisements. And she usually clicks the wrong place before downloading the YouTube video via the website.

Due the above reason, I determine developing the YouTube video downloading website and it can resolve the above issue currently.

How I built it

For integrating the GitHub action setting, it's available here.
- I use the GitHub action to setup the Python 3.8 environment and make some tests automated with pytest.

I use the following techniques to complete above website development:

Python 3.8+
FastAPI
Bootstrap 4

I use the following techniques to complete the unit tests:

pytest
pytest-mock
Fast API testing

I learn how to use above packages to complete unit tests. And it includes mocked test approaches.

My RSS Cache App for storing the RSS cache

My RSS Cache

Sometitmes the RSS feed caching is not implemented, customizing the RSS cache for my favorite RSS feed.

How it works

How the data is stored:

The RSS data contents is stored in the single key and data type.
- For each RSS data contents:
  - The lic_nttu_rss is the key and its value is the RSS XML feed contents.
  - The lic_nttu_rss_expired is the key and its value is current timestamp for fetching the RSS contents.

How the data is accessed:

Here is the sample code to access the RSS feed and expired with Python Redis OM:

from redis_om import get_redis_connection

# Get the RSS feed
rss_contents = redis_conn.get('lic_nttu_rss')

# Get the RSS expired value
expired = redis_conn.get('lic_nttu_rss_expired')

How to run it locally?

Prerequisites

Python - 3.8+
pip - 21.1.1+

Local installation

Cloning the repository with git clone command.

Listen the "I want to buy the COVID-19 test kit" website with Appwrite!

peter279k — Wed, 11 May 2022 08:24:00 +0000

Instructions

Since one month ago, the Omincron epidemic is outbreak and the local cases are increased every day in Taiwan.

To detect the Omincron, the COVID-19 test kit is more and more important. However, the test kit in Taiwan is not cheap enough for people. To solve the above problem, the government decides to expropriate the test kit.

And it can let them be cheap for people to be available to buy. These expropriated test kits will let some pharmacies sell and each pharmacy can get 78 test kits from government every day.

People who have the last number of their ID number is odd can go to the pharmacy and buy the 5 test kits at most on Monday, Wednesday, Friday and Sunday. And the people who have the last number of their ID number is even can go to the pharmacy and buy the 5 test kits at most on Tuesday, Thursday, Saturday and Sunday.

To let people realize where pharmacy is available to buy the test kit, I fetch the open data about pharmacy test kits that is generated by Taiwan CDC. And develop the simple website to let people type keywords to search the pharmacy and test kit numbers.

Overview of My Submission

The website is simple, and I use the jQuery to develop the front-end.

Then using the pharmacy test kit data to be the source data and let the jQuery parse the CSV data then present them in the web page finally.

I provide the website for people to browse and the available links are as follows:

Introduce to my Taiwan COVID-19 news website and crawler

peter279k — Tue, 07 Dec 2021 15:27:28 +0000

Instructions

In Taiwan, it's COVID-19 outbreak on May 13 and there're about 100 local cases every day. And it's zero local case since October.

At that moment, I'm really concerned about daily local cases so I develop this project and publish it to the GitHub. I use the cron job feature to fetch the latest COVID-19 news and publish my new web page during GitHub action running.

My Workflow

My completed workflow files are available here and it includes following YAML files:

fetcher.yml, this YAML file is for fetching latest COVID-19 news and store them to be JSON file. This web crawler is written in Python. And It will be run every hour.
web_build.yml, this YAML file is for publishing new website and loading new JSON file. This website is written in JavaScript with Vue.js framework. And it will be run every seventy minutes.

Submission Category:

This category is for DIY-Deployments and I hope developers love this and can be referenced :-).

Emask Notifier - DigitalOcean App Platform Hackathon

peter279k — Sat, 09 Jan 2021 19:11:26 +0000

What I built

Emask Notifier is a background worker that running a process and managed by Supervisor daemon.

This notifier can monitor this Emask website and check whether the e-Mask can be available for buying.

At this moment, it doesn't have the public API service for everyone because it's only for people in Taiwan.

To be private usage, it's only for my friends to let them receive the notification message and know the masks are available to buy.

In the future, it will have the contact form to let people in Taiwan can allow this notifier sends notification via Vonage SMS API to specific cell-phone number.

Category Submission:

Program for the People

App Link

At this moment, it's not available because this is the notifier and it's running as the background process on the targeted operating system.

Screenshots

If someone is in the default phone lists, it will get following SMS message:

Description

If developers want to setup own notifier for this eMask notifier, it's very easy to build.

And the completed README is available here.

Background

When the COVID-19 is ravaging the world, the mask is very important for people to avoid droplet infection.

Fortunately, the Taiwan government provides the e-mask website for Taiwan people to buy ten masks per two weeks.

However, the website doesn't have the subscription service that sending the notification via SMS to people and notify them buying masks.

That's the main reason why I build this notifier worker and setup the process running on the operating system :).

I'm grateful for these services to help me to complete this notifier:

How to create own Packagist mirror site on Ubuntu 18.04

peter279k — Wed, 24 Jun 2020 19:16:00 +0000

Introduction

If you're a modern PHP developer, you may heard about the packagist.org and composer.

The Packagist is a PHP package repositories and it stores many composer-based packages.

What about Composer? It's a package manager for PHP and it can help PHP developers to be easy to manage all kinds of PHP packages via Composer.

And its functionalities are very similar with NPM (a Node.js package manager).

If you use a lot for installing PHP packages via Composer, you may know about this issue.

This issue is about the main Packagist of Asia mirror has the bandwidth problem. (For now, it has been fixed.)

And it causes many PHP developers cannot install some PHP packages via composer install, composer require and composer update at that moment.

I also notice this issue and try to find another mirror to replace.

However, most of mirror locations are listed on official Packagist Org and this are far away from me.

And sometimes these locations cannot save my time because it takes slow time during composer package installation.

To resolve this issue, I want to setup my own Packagist mirror sites in my country.

And I also use packagist-mirror to accomplish my above issue because this mirror setup is recommended by packagist.org.

In this tutorial, I will show you how to use my customized Bash script to setup our own Packagist mirror site on Ubuntu 18.04 hosting system.

Perquisites

Here are some required stuffs before we get started with setting up our amazing Packagist mirror site:

One VPS (virtual private server) with at least one core CPU, 2GB RAM and a clean Ubuntu 18.04 operating system.
A registered domain, it's nice to let developers be easy to know mirror site and use it.
wget command is available now on your VPS.
It's nice to have a .env file on current home directory.
It's nice to have the nginx-default and nginx.conf files are located on current user home directory.

Installation

If you've looked at the packagist-mirror repository, you may find it has many kinds of ways to install the Packagist mirror site.

Including Docker container building, hosting setup and so on.

In this tutorial, I will use the hosting way to install the Packagist mirror site and I also provide a automated Bash script to help developers to setup Packagist mirror happily :).

Step 1: Download a packagist_mirror_installer.sh script

It's easy to use following command to download a packagist_mirror_installer.sh:

wget https://gist.githubusercontent.com/peter279k/cab67ba6207ec291747cc3cc6071a519/raw/46495d8dad37e769f4065f46925ff7b8d22b1e7e/packagist_mirror_installer.sh

After script downloading has been completed, it can change this Bash script permission into 755.

That is, owner can read, write and execute this script, and group owner or other users can read and execute the script.

Step 2: Run this packagist_mirror_installer.sh script

After setting above permission is successful, executing following command to start Packagist mirror site building:

./packagist_mirror_installer.sh

And it will present following captured picture:

It's doing for update and installing required packages.

By default, the system locale will setup for en_US.UTF-8.

If developers want to change locale, it will set specific locale manually.

When installing required packages has been done, it will present following pictures to let developers select current timezone:

After selecting timezone has been done, it will present following picture to tell developers setting a host name for this mirror site:

If developers don't set any host name and type enter, script will try to use hostname to get current host name on this hosting operating system. And ask you to ensure set this host/domain name.

If the host name is configured correctly, developers can type Y or y to continue the next step.

Copy nginx.conf and nginx sites default files

After setting the host name is successful, the script will try to find the nginx.conf and nginx-default files on current user home directory.

If it doesn't find any Nginx configuration files, it will ask you to skip this copy work and do next step.

If developers type Y or y, it will skip above steps. Otherwise terminate this script with exit code 1.

After doing above steps about copying Nginx configuration files, it will present following picture to tell whether developers to delete all files/folders on /var/www/html/* directory.

If typing Y or y, it should delete all of the things on /var/www/html directory.

After manipulating the /var/www/html folder, it will ask developers whether updating Packagist repository:

If developers type Y or y, it will use git pull origin master command to update Packagist repository right now. Otherwise skipping this step.

After updating Packagist repositories step, it will present following picture:

It will do following steps for above captured picture:

Download Composer.
Using composer install to install some packages for packgist-mirror repository.
Asking developers whether executing the composer update -n to update dependencies for above repository.

After doing some steps, it will present following picture to tell developers whether syncing Packagist mirror:

If developers type Y or y, it will use php bin/mirror create -vvv command to update Packagist repository right now. Otherwise skipping this step.

After syncing or skip Packagist mirror syncing step, it will present following picture:

It does some steps:

Update package mirror for Ubuntu operating system and install required packages for cert-bot. This can help developers to install a Let's Encrypt SSL certificate to secure mirror website easily.
Asking developers to determine setup SSL certificate with cert-bot:

If developers type Y or y, it will do cert-bot command interactively.

And help developers to setup and configure a SSL certificate quickly.

Editing DotEnv file

Editing .env file is very simple, and developers can scratch this file from .env.example file.

And it's very clear for every developer to know each DotEnv values have the comment and let us know setting functionality easily.

Customizing index page

If developers want to customize index page, it's easy to edit the index.html.php file.

Summary

After doing above Bash script correctly, it will have this page.

Enjoy it and have your own Packagist mirror right now :)!

How I built it

I use the PCRE (Per Compatibility Regular Expression) to validate specific payment pointer URL on PHP. And it can call WebMonetization::validatePaymentPointer to complete above specifictaion.
I create configuration array wit PHP to define a default payment pointer URL prefix lists. These lists are as follows:
- $ilp.uphold.com/
- $ilp.gatehub.net/
- $pay.stronghold.co/ It can call WebMonetization::getDefaultPaymentPointerUrls method to complete above specification.
To crate completed payment pointer URL string easily, I also create a method named WebMonetization::generatePaymentPointer to complete above specification.
To create payment pointer URL with meta tag string easily, I also create a method named WebMonetization::generateMetaTag to complete this specification.
To make all of static methods verified and reliable, I also develop unit tests with PHPUnit to complete above specifications. All of unit tests are available on WebMonetizationTest class.
To make sure all of above static methods are verified and reliable, I also integrate the GitHub Action Workflows to complete this issue about do automatic PHPUnit tests for every incoming commits. The latest GitHub Action Workflows status is available here.

Additional Resources/Info

Here are some useful resources and info to help me to complete this simple and useful PHP packages:

PCRE reference and function usages on official PHP website.
The payment pointer URL specification and description is available here. And it can help me to know more details about generating payment pointer URL :).
To complete all of static methods I develop on WebMonetization class reliably, I also want to say thanks for PHPUnit to help me to complete all related static methods with unit tests.

Let's build a Web Service with Web Monetization X PHP Binding!

peter279k — Wed, 03 Jun 2020 17:25:56 +0000

[Instructions]:

In this Hackathon, it can learn about how to develop some popular web service with Web Monetization features and PHP binding.

What I built

Here are some stuffs I build for this dead simple web service:

Using Bootstrap to develop all required templates.
Using PHP 7.2+ version with Slim 4 Framework to build a web service.
Using the Twig view template to be back-end rendering exclusive contents.
Using PHP session to record current Web Monetization status event.
In development mode, using mkcert command to create self-signed certificate easily.
In development mode, using the stunnel command to create SSL tunnel and make local PHP web bulit-in server can be served on HTTPS. (It's important for Web Monetization because this only supports over HTTP.)
In production mode, using the certbot to create HTTPS easily.
Both development mode and production mode are on Ubuntu 18.04.

Submission Category:

Here are some categories included in this Hackathon:

Foundational Technology: using the PHP to be back-end binding.
Experiment stuffs: let all some stuffs and put them together to be a development environment.
Production stuffs: After completing this service in development environment, I also provide the deployment steps to publish in production mode.
Automatic Building Steps: I want to save my life, so I develop a simple Bash script to build my development environment easily.

Demo

Firstly, visiting the following website via web-monetization.peterli.website, and it will present following captured picture:

Second, the Home and Introduction don't have the web-monetized feature, they're the simple page.

Third, click the Blog link. By default, this page with web-monetized is disabled. And it will only look at the warning message about "This is the locked section one, You've to enable and pay with Web Monetization to unlock it :)!".

And the danger message says: "The Web Monetization has been disabled!".

To enable the web-monetized, we can just click the "Enable Web Monetization".

Once click this button, it will refresh this page and it will look at these exclusive contents:

If people thinks this is enough to do web monetization, they can click "Disable Web Monetization" button.

If people want to do web monetization for about whiles, they don't have to click disabled button.

They can enable web-monetization and leave this page directly.

The web service will use PHP session to remember this until the session has been expired.

If people want to know how much amounts are sent to this author, they can use the "Calculate Web Monetization" to present total amounts:

If people want to stop knowing the amount information, just click "Stop Calculating Web Monetization".

Then visiting the donation page:

It's alternative way to do donation.

Sometimes most of developers have the PayPal donation button or other payment donation buttons to let sponsor pay some dollars.

Every payment donation buttons need to have the minimum dollars to let sponsor pay. For example, 1, 5 or 10 USD dollars at least.

This is not very convenient for every sponsor and it's up to sponsor determine how much amounts paid for developer.

The donation page are developed for these sponsors.

If some sponsors want to pay small amounts to developers, it can just click "Enable Donation Page".

And this donation page will enable the web monetization page.

Once enabling web monetization page, it will start paying some amounts and present current amount they pay for this developer.

Once the sponsor thinks it's good enough to do this payment, they can click "Disable Donation Page" at any moments!

Finally, visiting History page. In this page, it can show how much amounts that this website owner has made.

I think amounts should be public and it can let every user and sponsor know the total amounts of this website.

Link to Code

All codes are located on web-monetization-demo. Feel free to fork and use them :).
It also provides a completed README for every back-end developers to develop a awesome web-based application services steps by steps.

How I built it

I think these exclusive contents should be hidden. And I use the Twig view to complete this issue.
To sync transaction history for every micro payment sent to Coil , I still use the AJAX to do POST method to store every amount detail.
To let developers decide to enable/disable web monetization, every page I develop has the enable and disable button.
