Reflections on Early Versions

The predecessor of all current TechUI frameworks originated from the early TechUI-Vue2 paid framework. The development of this framework actually stemmed from a series of technical validations.

Therefore, at the beginning of this framework's release, there were too many complaints and pain points, which ultimately led to the complete failure of the promotion of the early framework. Looking back now, TechUI-Vue2, which underwent several major updates, can at best be considered an Alpha (internal testing) version.

Complex License System

Early versions designed an extremely complex license classification for the sake of so-called "commercial protection". The original intention was to improve user stickiness, but upon later reflection, these settings (such as development environment validity) were disastrous.

License Type	Validity (Dev/Prod)	Core Restrictions	Evaluation (Reflection)
Advanced License (Unreleased)	Permanent / Permanent	Main system name locked; Supports custom secondary subsystem names	Ideal state in conception, but never implemented.
Official License	1 Year / Permanent	Development environment forced to expire in 1 year; Contact customer service for free updates upon expiration; Production environment unrestricted; System name locked	One of the stupidest settings. Although updates were free, it artificially created maintenance obstacles.
Temporary License	3 Months / 3 Months	Cannot pack/deploy; Cannot use debugging tools	Extremely poor experience. Sacrificed developers' basic tools to prevent cracking.

Note: The above settings were for the early TechUI-Vue2 version. At that time, the version was more for technical validation, trying to combine Wasm modules to see to what extent frontend libraries could be restricted. Now it has been completely rectified, please use with confidence.

Reasons for Failure

The core reasons can be summarized as: Blind Confidence and Pricing Detached from Market.

Blind Confidence

Before the popularity of mature competitors like DataV, the market lacked usable visualization component libraries. The early market gap gave us blind confidence, thinking "making it alone is a dimensionality reduction attack," ignoring user experience.

Excessive Pricing

TechUI-Vue2's pricing strategy was completely decided "on a whim"—simply referencing the cost of a single outsourced project. This led to ridiculously high prices, eventually forcing the vast majority of licenses to be given away for free to friendly enterprises, making commercialization exist in name only.

Programmer-style Mindset

The way of thinking was too straightforward and linear, never doing real market research. (Frankly, I haven't completely changed even now; launching the new TechUI is more about the sentiment of completing "unfinished business" rather than pure commercial calculation.)

Extreme Defensive Measures

To validate technology, we conceived and implemented a large number of frontend-based "defensive measures". The vast majority of these measures severely sacrificed the developer's user experience (e.g., prohibiting debugging).

Single Authorization Method

Although there were nominally four types of licenses, the core logic was only one: Binding Project Name. Although there were plans to develop "company-level universal authorization," with the failure of project promotion, this feature was also aborted.

Unreasonable Development Kit

This was a technical flaw that led to user loss.

• Cumbersome Configuration: To solve the configuration difficulty, we launched a "configuration-free development kit," which instead increased the mental burden on developers.
• Current Status: The new TechUI has been completely modularized, supporting on-demand import, and is no longer forcibly implanted via a "family bucket" method.

Defense Measures

The early TechUI-Vue2 was simply a testing ground for frontend attack and defense technologies. The original intention was to pursue "Extreme Security (Restriction)," resulting in "Extreme Terrible Experience". Below is the specific review and new improvements:

Service Termination Popup

• 🔴 Early Mechanism: Once violations like title tampering or license expiration were detected, it would directly clear DOM elements and pop up a full-screen warning, causing system paralysis.
• 🟢 New Improvement: Removed the violent clearing logic, changing it to gentle console prompts or watermarks.

System Title Verification

• 🔴 Early Mechanism: To prevent users from modifying the authorized project name, we conducted all-around DOM monitoring on browser tabs, Loading interface, system title components, and control panels. Any modification at the JS or CSS level would trigger the Kill Switch.
• 🟢 New Improvement: Only retains tamper-proof monitoring on the browser tab (Title), no longer restricting the freedom of UI components.

Prohibit Debugging

• 🔴 Early Mechanism: Implemented based on devtools-detector.js. Temporary licenses completely prohibited debugging; official licenses prohibited debugging after packing (required entering a hidden code to bypass). This made online troubleshooting extremely painful, even requiring license decompilation to get the debug code. This was also an extremely rigid and stupid restriction.
• 🟢 New Improvement: Completely removed mandatory restrictions. This feature has been refactored into an independent PanicAlert component, handing the power of "whether to prohibit debugging" back to the developer.

Validity Verification

• 🔴 Early Mechanism: Not only detected temporary licenses but even official licenses would detect if the "development status" had expired (i.e., the 1-year limit mentioned above).
• 🟢 New Improvement: Except for development licenses, all licenses are permanently valid.

Version Locking

• 🔴 Early Mechanism: The license was strongly bound to the component library version. If versions did not match (e.g., license restricted to 0.1.1, current library is 0.2.1), the system refused to run. This was a bad policy to prevent compatibility issues due to too many breaking updates during the Alpha phase.
• 🟢 New Improvement: Temporarily retained. Because the current TechUI 3.0 is still in the Beta phase, breaking updates may exist. This restriction will be removed after entering the Stable phase. (Current version restrictions are broad; version differences within 0.5 can be used, and this feature will be directly removed later)

Environment Fingerprint

• 🔴 Early Mechanism: Actively detected the running environment (IP/Domain) to restrict packing and deployment.
• 🟢 New Improvement: New licenses (including free versions) no longer actively detect environment parameters. The original environment monitoring capability is encapsulated into the PanicAlert component, available for user invocation on demand.

Apology Statement

On behalf of the TechUI team, I offer my sincerest apologies to all users who have used early versions of TechUI (Vue2 / Lite) for the many unreasonable restrictions and terrible development experiences previously!

It is precisely your tolerance and feedback that gave birth to today's more open and reasonable TechUI 3.0.
