PWAs: Will The Web-based Apps End Big Tech App Store Tyranny?
July 12, 2024

Progressive Web App(PWA) is basically a website built to function as a native desktop software or mobile app. The main advantage of a PWA is that it is apps store-independent and cross-platform.

Opening a PWA-optimized website like 'Gab.com' for example, on a standards-compliant browser like Brave would immediately trigger an instal prompt on the top-right corner of the browser window within the address bar.

On mobile browsers, the PWA prompt may be 'install Gab' or 'add Gab' [to the homescreen]. In the absence of the prompt, just adding the website to the homescreen will do the trick.

Once installed, the PWA functions more like a native app. This circumvents app stores like Google Play and Apple's App Store where free speech apps like Gab are banned.

Other browsers that support PWA include Gab's own Dissenter, Microsoft Edge, Google chrome, Apple's safari and Opera mobile. PWAs are supported on Windows 10, android and iOS.

For a website to be a PWA, it must run on certain core web technology components. And while User Interface frameworks like Angular and React support and have all the components for PWAs, it is important to note that PWAs are not framework-dependent.

PWAs store data as HTML files, use CSS and images from the browser cache which makes them load faster and also work offline by utilizing a specific set of components.

Critical components of a PWA includes Service worker, JSON manifest, App shell and other tools that continue to be added as UI frameworks and standards evolve.

A service worker is a type of web worker. It’s a JavaScript file that runs separately from the main browser thread, intercepts network requests, caches, and delivers push messages. If there is no network connection, a service worker will pull data from the cache using the browser’s cache API.

JSON manifest is a file that contains metadata of the app describing the UI. The manifest controls whether the app will have a more native rendering, the icon to be displayed on the home screen when installed, the orientation, the full-screen rendering, and so on. The manifest is responsible for creating an app-like experience.

App shell is the container where the data is stored. The app shell architecture consists of HTML, CSS, and JavaScript and allows some lightweight settings to be quickly loaded during the first visit, which reduces the time required the first time the PWA is launched. The app shell is responsible for the UX of the PWA.

Note that PWA components are based on common and open web technologies, hence keeping the development independent of any one app store software development kit(or SDK).

Google and Microsoft are working together to support the PWA ecosystem. Google has been adding PWA components -- like workbox, chrome Devtools and lighthouse -- to their UI frameworks.

The technologies behind PWAs are not new. Steve Jobs tried this in 2007 with HTML5-based standard for web apps on iphones. Apple later changed course with the introduction of iOS SDK.

Web technology development has since advanced, and JavaScript is becoming a computational power. Most PWAs are more feature-rich than their traditional native counterparts.

Advocates claim that with PWAs, smartphone users don't need to worry about app updates and storage space; and developers don't have to grovel to the big tech app store duopoly of Apple and Google, to distribute their PWAs. Gab social and other apps banned from Play store and App Store, are taking advantage of PWAs to great success.

Ironically, the tech giants are embracing PWAs, probably for different reasons and the fact that the general trend is towards 'stream everything.'

ZDNet's Mary Jo Foley reported last year that Microsoft is building an Azure-powered 'Cloud PC' service to be launched this year. With such service, Windows 10 operating system users can access and interact with the OS via a browser, making windows 10 accessible on any 'thin client.' A windows 10 PWA on android, iOS or Mac can give one access to the OS without having to worry about updates and graphics power of your device. The crunching of data is done behind the scenes on Microsoft servers.

Microsoft has also released popular apps like Office and outlook as PWAs. The tech giant accepts PWAs from developers who wish to distribute via their windows 10 app store.

Google has released their popular services as PWAs. These include YouTube music, map, photos, Drive, Keep and stadia. Google Play store also supports PWAs. Twitter Lite is a PWA.

With gaming being the only holdout for now in the 'stream everything' race, it may not be too optimistic to say that in 5 to 10 years, the tyrannical regime of the app store duopoly -- Google and Apple -- will be have ended. Though they obviously will not go down without a fight.

Trump Backs Down From Planned Military Strikes On Iran, Amid US General's Warning About Insufficient Assets To Defend Israel

President Donald Trump has called off planned U.S. military strikes on Iran. In a Truth Social post early morning UTC Sunday, he claimed Iran and other Middle Eastern countries asked him to cancel the planned operation, after the “perimeters of a deal” were agreed to.

Trump wrote, "The U.S.A. is locked and loaded and ready to go against the Islamic Republic of Iran, at levels of Military Terror, Strength, and Power not seen since World War II. Despite this, we have just been asked by Iran, and other Middle Eastern Countries, to hold off any attack in that the perimeters of a deal has been agreed to.

"This would include the Immediate, Complete, and Total OPENING OF THE HORMUZ STRAIT, and an end to Iran’s nuclear threat. Based on this request, I have agreed, for the future benefit of the WORLD and, likewise, the survival of a successful and prosperous Iran, to cancel the attack, subject to being able to rapidly make a DEAL.

"The Country of Israel joins me in this commitment. Get to work, everybody, and get it DONE. Thank you for your attention to this matter! President DONALD J. TRUMP."

The announcement came a day after he threatened that the U.S. military will pummel Iran, and reportedly target the country's civilian infrastructure. “We will be hitting them very hard,” Trump said during a televised press conference Friday at Camp David. “And you know at some point, they’re going to say, ‘We just can’t take it anymore.’”

Trump's reversal comes amid report that Gen. Alexus Grynkewich, head of U.S. European Command (EUCOM), reportedly privately warned the Pentagon that he lacks sufficient naval forces to protect Israel from Iranian ballistic missiles, stating he would be forced to prioritize the U.S. homeland without an additional Navy destroyer.

US General Warns Pentagon About Insufficient Forces To Defend Israel, 'Forced To Choose' Defense Of US Homeland

Gen. Alexus Grynkewich, head of U.S. European Command (EUCOM), reportedly privately warned the Pentagon that he lacks sufficient naval forces to protect Israel from Iranian ballistic missiles, stating he would be forced to prioritize the U.S. homeland without an additional Navy destroyer. This warning, sent in a written letter, highlights severe strain on U.S. military resources as the conflict with Iran enters its fifth month.

Pentagon officials described the memo as a standard "operational risk warning" that commanders issue when competing for scarce global military assets.

The U.S. Navy has five destroyers based in Rota, Spain, with a sixth expected later in the year, but maintenance backlogs due to high operational tempo have reduced availability. Currently, two destroyers are in the eastern Mediterranean, three are in Rota, and one is in the Red Sea, with another fleet operating near Iran.

Sustained engagements shooting down Iranian and Houthi ballistic missiles have rapidly consumed Standard Missile-3 (SM-3) and SM-6 interceptors faster than U.S. defense industrial lines can produce them.

U.S. forces, including THAAD and naval interceptors, have shouldered the bulk of defending Israel from Iranian attacks, often more frequently than Israeli systems. Supplies of key defensive weapons, including Patriot missiles, are reportedly depleted.

EUCOM's forward naval footprint relies on five Arleigh Burke-class destroyers based out of Rota, Spain. Two destroyers—the USS Paul Ignatius and USS Roosevelt—were operating in the Mediterranean Sea to shield Israel. Three others (USS Arleigh Burke, USS Bulkeley, and USS Oscar Austin) were anchored at Rota due to maintenance backlogs resulting from continuous operations.

Simultaneously, the U.S. Navy has deployed two aircraft carrier strike groups (USS George H.W. Bush and USS Abraham Lincoln) along with 11 destroyers in the Arabian Sea, plus the USS Gonzalez in the Red Sea to protect commercial shipping from Houthi strikes.

EUCOM must balance defending Israel with maintaining readiness against potential Russia incursions into NATO territory, as Russia also possesses ballistic missiles capable of striking the U.S. mainland. Keeping destroyers locked into anti-missile duty near Israel dilutes EUCOM’s ability to cover NATO contingencies.

Iran closing the Strait of Hormuz and Trump administration imposing a naval blockade of Iranian ports, have forced the Navy to divide assets among the Mediterranean, Red Sea, and Arabian Sea, complicating defense commitments.

The warning comes as the Trump administration reportedly plans further escalation, including strikes on Tehran’s electricity infrastructure. The collapse of ceasefire talks has led to near-daily missile exchanges, increasing inflationary concerns and political pressure ahead of the 2026 midterm elections in the U.S.

At Camp David, President Trump told reporters that Iran’s military had been "decimated" but criticized Iranian negotiators as "dishonorable and dishonest" after renewed missile fire targeted U.S. positions in Jordan. When asked if Americans should expect continued back-and-forth military strikes, he acknowledged: "A little bit... We just want to win. They cannot have a nuclear weapon."

Israeli Airstrikes Kill At Least 4 In Gaza, Day After Trump Announced 'Historic' Hamas Disarmament Deal

Israeli airstrikes killed at least four people in Gaza on Saturday, just hours after Donald Trump and his Board of Peace announced a "historic" roadmap for the complete disarmament of Hamas and a phased withdrawal of Israeli forces.

“Today, the Board of Peace reached a HISTORIC agreement for the COMPLETE DISARMAMENT of Hamas and all other armed groups in Gaza,” Trump wrote in a Truth Social post. “This is a monumental step toward lasting PEACE and SECURITY.”

The agreement stipulates that disarmament and withdrawal must occur in "lockstep," yet Israel has not officially accepted the plan and continues military operations.

Tensions escalated when notorious Jewish extremist and Israeli minister Itamar Ben-Gvir labeled the agreement "unacceptable," insisting that "assassinations in Gaza must continue." Consequently, the IDF struck multiple targets, including weapons depots and medical warehouses near Al-Aqsa Martyrs Hospital, killing civilians and wounding others.

The 14-point roadmap, finalized in Cairo with mediators from Egypt, Qatar, and Turkey, outlines a transition where Hamas decommissions weapons while the IDF gradually withdraws.

Key provisions of the agreement include:

Phased Disarmament: Hamas agrees to hand over heavy weapons to a new technocratic body, the National Committee for the Administration of Gaza (NCAG), over an estimated 200 to 320 days.

Security Transition: An International Stabilization Force (ISF) and a new Palestinian police force will assume security responsibilities as Israeli troops pull back.

Verification: An international verification committee will monitor compliance, with the principle that "withdrawal must move in lockstep with decommissioning."

Despite the announcement, Israel has not formally accepted the deal, with officials demanding complete demilitarization as a precondition for any withdrawal. Ghazi Hamad of Hamas insisted the group would not disarm prior to Israeli withdrawal, calling the deal a draft pending Israeli commitment.

While Trump hailed the agreement as a "monumental step toward lasting peace," the violence underscored deep skepticism and unresolved conditions between the parties, signaling a potential stalemate in implementing the ceasefire.
