The article, titled "Intégration et Authentification Firebase sur iOS" (Firebase Integration and Authentication on iOS), serves as a tutorial and comprehensive guide on integrating and configuring the Firebase back-end as a service (BaaS) platform within an iOS mobile application, with a specific focus on user authentication.

Here is a summary of the key content:

Firebase as a Solution for Rapid Prototyping

The article highlights that mobile applications require a back-end server for user login and data synchronization. Firebase makes it easy for developers to test out ideas quickly—an era characterized by rapid prototyping—by providing essential back-end functionality, such as authentication, database services, and object storage, thus eliminating the need for server-side coding knowledge or time. Furthermore, Firebase includes useful capabilities for prototype validation, including analytics, A/B testing, and push notifications. The service is free for small projects.

Step-by-Step iOS Integration

The core of the article outlines the technical steps required to set up an iOS project (named MyFirstFirebaseApp) with Firebase:

1. Project Setup: Creating a new Single View App Xcode project.

2. Dependency Management: Initializing and using CocoaPods to add the prerequisite libraries via the Firebase/Core pod.

3. Firebase Account Configuration: Creating an account in the Firebase Console (a Google product) and creating a new project. Although free for prototyping, the author notes the need to be aware of the pricing structure for production use.

4. App Registration: Registering the iOS app, downloading the essential GoogleService-Info.plist file (which contains basic configuration information like client ID, API Key, and database URL), and adding it to the Xcode project.

5. Initialization: Adding the initialization code (import Firebase and FirebaseApp.configure()) to the AppDelegate.swift file to ensure Firebase is correctly set up when the app launches.

User Authentication and Management

The article details the various user management and sign-in options available through the Firebase Dashboard's Authentication section, where developers can choose one or multiple methods:

• Standard Methods: Email/Password, Google, Facebook, Twitter, GitHub, and Anonymous guest accounts.

• Phone Authentication: Allows sign-in using a mobile phone number, with Firebase SDK tools for verification. This method is free for the first 10,000 logins per month under the free Spark plan.

Implementing Phone Authentication

The tutorial dedicates significant attention to configuring and implementing Phone Authentication in Swift:

1. Configuration: Requires enabling Phone authentication in the Firebase Console and including the Firebase/Auth pod.

2. Push Notifications and reCAPTCHA: It necessitates enabling push notifications in the Xcode project. It also requires configuring reCAPTCHA verification (using the REVERSEDCLIENTID in the Xcode URL Schemes) as a fallback mechanism if silent push notifications cannot be received (e.g., when using an iOS simulator or if background refresh is disabled).

3. Cloud Messaging Setup: The tutorial includes instructions for configuring Firebase Cloud Messaging (FCM) by uploading APNs certificates and the APNs authentication key to the Firebase Console.

4. Code Implementation: The provided Swift code utilizes RegistrationService to call PhoneAuthProvider.provider().verifyPhoneNumber, which sends a One-Time Password (OTP) to the user's phone. Upon receiving a verificationID, the app prompts the user to input the OTP via an alert dialog. Finally, the signIn method creates a Firebase credential using the verificationId and the OTP, completing the user sign-in process.

This cheatsheet provides practical, open-source approaches (version 1.1.2, 2025-03-28) for making websites and web applications accessible to everyone.

Design for Accessibility Principles

1. Use Semantic HTML: Employ a logical headline order and structuring elements like <header>, <footer>, <ul>, and <p>. Semantic HTML helps screen readers understand the content structure and meaning.

2. Provide Text for Non-Text Content: All content not represented by text must be made visible to screen readers. This involves providing concise descriptions in alt attributes for content images and charts, and ensuring CAPTCHAs are also accessible.

3. Label Form Elements: Form input elements require linked <label>s for screen reader access (e.g., <label for="search">Search</label><input id="search">). The placeholder attribute is not an alternative.

4. Show Focus Visibility: When navigating by keyboard, the currently focused element must be visibly highlighted. Interactive elements should be focusable by default and focused in a useful order (e.g., use a <button> instead of a <span>).

5. Use Contrasting Colors: Ensure adequate color contrast.

6. Understandable Without Color: Colors should not be necessary to understand the content or its current state. For example, do not highlight errors solely with red text; add a subsidiary icon.

7. Write Descriptive Links: Links should be descriptive.

8. Caption Video and Audio: Provide text alternatives (captions) for both pre-recorded and live video and audio content. Voice recognition software can assist in creating captions.

9. Keep Pinch and Zoom Alive: Pinching to zoom is important for low vision and aging users. Use the <meta name="viewport" statement with user-scalable="yes". Avoid using user-scalable="no" and maximum-scale: 1.

10. Use WAI-ARIA Sparingly: WAI-ARIA should only be used if necessary, particularly for complex dynamic sites (such as single page applications). Semantic HTML should always be considered before using WAI-ARIA.

Methods for Testing Accessibility

1. Zoom to 400%: Use the browser or document viewer zoom to verify that all text remains visible.

2. Check Keyboard Navigation: Navigate solely using the standard keyboard keys: ← ↑ ↓ →, TAB, SHIFT+TAB, ESC, SPACE, and ENTER.

3. Use a Screen-Reader: Turn off the monitor and use a screen reader, such as Apple Voiceover or NVDA on Windows.

4. Run Lighthouse Audit: Execute the Lighthouse accessibility audit, which is located in the “Audits” section inside of the Chrome DevTools.

5. Deactivate CSS: Check if the document structure still makes sense when CSS is deactivated.

PDF.js is a project structured into distinct architectural layers designed to handle the interpretation, rendering, and display of PDF files.

Here are the principal functionalities and features of this tool:

1. PDF Interpretation and Rendering

PDF.js functions by separating core processing from user interaction through three distinct layers:

• Core Layer: This foundational layer is responsible for parsing and interpreting a binary PDF. It is the basis for all subsequent layers, although direct use of its API is considered advanced.

• Display Layer: This layer uses the Core layer to expose an easier-to-use API. Its main functions are to render PDFs and extract other information out of a document.

• Viewer Layer (User Interface): Built on the Display layer, the Viewer provides the UI for the PDF viewer utilized in Firefox and other browser extensions. This viewer component can serve as a good starting point for building your own viewer.

2. Customization and Development

The Viewer layer offers a ready-made UI, but creators are asked that if they plan to embed it in their own site, they should re-skin it or build upon it rather than using an unmodified version.

3. Accessibility and Distribution

PDF.js is designed for flexible distribution and deployment:

• Prebuilt and Source Versions: The tool is available in both Prebuilt (for modern and older browsers) and Source versions. The source code can be cloned using Git.

• CDN Inclusion: PDF.js is hosted on several free CDNs (including jsdelivr, cdnjs, and unpkg) for easy inclusion into web projects.

• Browser Support: Information about supported browsers is maintained on a dedicated wiki page.

• Testing and Examples: The source and prebuilt versions include a testing PDF file (compressed.tracemonkey-pldi-09.pdf) and various folders containing simple usage examples. The distribution also includes translation files in locale/ and l10n/.

Definition and Philosophy

Microjs.com is a "micro-site for micro-frameworks" and micro-libraries. This concept contrasts with the use of favorite monolithic frameworks, which are often bulky (50K, 100K, 150K, or more) and where the majority of the code is not truly utilized by the user.

Micro-frameworks are metaphorically described as the "pocketknives of the JavaScript library world", offering a quicker and smarter solution than a "ride-on John Deere tractor with air conditioning and six-speaker sound system".

Fundamental Characteristics of Micro-frameworks

Micro-frameworks possess very specific characteristics:

1. Compact Size: They are very portable because their size is generally 5k and under (minified and gzipped).

2. Single Functionality: A micro-framework does one thing and one thing only — and does it well.

3. Code Purity: They are "short, sweet, to the point". There is "no cruft, no featuritis, no feature creep, no excess anywhere".

Functionality of Microjs.com

The primary goal of the Microjs.com site is to help developers:

• Discovery: It helps to discover the most compact-but-powerful micro-frameworks.

• Selection: It makes it easy for the user to pick one that will work for them.

• Contribution: The site allows the community to add their own frameworks by forking the site on GitHub, adding the framework to data.js, and submitting a pull request.

Microjs.com is an initiative of Thomas Fuchs, dating from 2011 to 2019.

WebPerl is a project designed to run Perl in the browser.

Core Technology and Functionality

• WebAssembly Port: WebPerl utilizes the power of WebAssembly (Wasm) and Emscripten.

Pijul is a distributed version control system (DVCS).

Here is a summary of its main features and functionalities:

Core Identity and Philosophy

• Version Control System (DVCS): Pijul is a free and open source (GPL2) distributed version control system.

• Patch Theory Basis: Its distinctive feature is that it is based on a theory of patches.

• Speed and Scalability: It is designed to be fast and scalable.

• Bootstrapped: Pijul is bootstrapped, meaning it is used for its own development.

Unique Approach to Changes and History

• Commutation (Order Independence): This is a key feature where independent changes can be applied in any order without changing the result or the version's identifier.

  • This property makes Pijul significantly simpler than workflows that rely on complex commands like git rebase or hg transplant.

  • Keeping your history clean is the default.

• Channels (Feature Branches): Pijul has a branch-like feature called "channels," but these are not as important as branches in other systems. Often, so-called feature branches are simply treated as changes in Pijul.

Merging and Conflict Handling

• Guaranteed Merge Correctness: Pijul guarantees strong properties on merges.

  • The most important guarantee is that the order between lines is always preserved. This contrasts with 3-way merge systems, which may shuffle lines around.

• First-Class Conflicts: Conflicts are treated as the standard case, not as a "failure to merge".

  • When the line order is unknown (due to concurrent edits), it is defined as a conflict.

  • A conflict happens between two changes and is solved by one change.

  • The resolution change solves the conflict between the same two changes, regardless of concurrent changes.

  • Once a conflict is solved, it never comes back.

Usability and Scalability Features

• Partial Clones: The commutation property makes it possible to clone only a small subset of a repository.

  • This works because one only needs to apply the changes related to that specific subset.

  • Changes produced while working on a partial clone can be readily sent to the large repository.

• Ease of Use: Pijul is designed to be easy to learn and use, without compromising on power or features.

This tutorial details the methods for comparing two dates in JavaScript.

The principal methods or "functionalities" described for date comparison are:

1. Using Relational Operators: You can compare two dates to determine which one is greater or smaller using the relational operators: <, >, <=, and >=. Examples demonstrate that comparing date1 (2018-05-26) to date2 (2018-05-23) using these operators yields the expected boolean output (e.g., date1 > date2 is true, and date1 < date2 is false).

2. Using getTime() for Equality Comparison: You cannot use the equality or inequality operators (==, !=, !==, ===) directly to compare the value of a date object. If two dates with identical values are compared using ==, the result will be false. If you want to use these equality operators to compare dates, you must employ the getTime() method. When getTime() is used on both dates (e.g., date1.getTime() == date2.getTime()), the comparison successfully yields true for matching dates.

The principal characteristics of the CSS rule display: contents are centered around controlling the element's box generation without affecting its content or underlying structure.

1. Core Functionality and Visual Effect

• Box Omission: When display: contents is applied, the surrounding rectangular box of the element is omitted entirely. This box normally consists of the border, padding, and margin areas.

• Content Display: The contents of the box (the content area) are drawn as normal.

• Conceptual Replacement: For the purposes of box generation and layout, the element is treated as if it had been replaced in the element tree by its contents. Visually, this is the same as imagining the element's opening and closing tags were omitted from the markup.

• Contrast with display: none: Unlike display: none, which prevents both the box and its contents from being drawn, display: contents only affects the box visually.

2. Interaction and Non-Visual Behavior

The rule primarily affects the visual representation; it does not affect the underlying markup within the document.

• Attributes and Targeting: The element still exists in the document and can still be selected, targeted, and interacted with using its attributes (e.g., ID). For instance, it can still be referenced using aria-labelledby.

• JavaScript Events: Event listeners set on the element (like a click event) will still trigger normally. Interaction is possible because the contents are visible.

• Pseudo-Elements: Pseudo-elements (::before and ::after) are considered part of the element’s children and are displayed as normal.

• Navigation Limitations: One notable issue is that users can no longer navigate to the element using a fragment identifier (hash link).

3. Special Behaviors for Certain Element Types

For elements whose appearance is determined by external resources or complex internal structures, display: contents behaves differently:

• Replaced Elements: For elements like images (<img>), which are controlled by external resources, applying display: contents functions exactly like display: none. The entire box and contents are not drawn.

• Complex Form Elements: For many form elements (such as <select>, <input>, and <textarea>), which are composed of several smaller elements rather than a single "box," display: contents also functions exactly like display: none.

• Buttons and Links: These elements do not have special behavior. The surrounding box is removed, but the content remains visible. Links still function for navigation, and buttons still attempt to submit a form if used within one.

4. Utility and Use Cases

• Semantic Layout Solution: This rule is useful for resolving conflicts between the need for semantic HTML structure (e.g., grouping content within an <article>) and the requirements of modern CSS layout systems, such as CSS Grid Layout.

• Enabling Direct Sibling Styling: CSS Grid often requires elements to be direct siblings to function correctly. By applying display: contents to wrapping elements (like <article>), the wrapper's children are treated as if they were direct siblings of the grid container, allowing complex layouts (like ensuring matched height sections across multiple cards) while preserving semantic grouping.

5. Browser Support

• At the time the source was written, display: contents was only supported in two major browsers.

• It should currently be treated as a progressive enhancement, and developers should use appropriate fallbacks (e.g., using @supports CSS queries).
