Most people don't understand the knowledge points of this article "What can Weixin Mini Programs (Mini) Development Libraries grace and wepy do?" Therefore, Xiaobian summarizes the following contents for you. The contents are detailed, the steps are clear, and they have certain reference value. I hope you can gain something after reading this article. Let's take a look at this article "What can Weixin Mini Programs Development Libraries grace and wepy do?"

Mini programs developer source

From front-end developers

So far, if it's a frontend, then it's likely that you've used one of Angular/React/Vue. First of all, if you haven't used Vue, then the learning cost of using wopy is close to the cost of learning Vue. Second, developers who believe strongly in Angular/React may ask, why do Mini programs have to be Vue when they are Mini programs? Authentic Vue is not used in web development, and will learn wepy again in order to develop Mini programs.

Non-frontend developers

After the release of Mini programs, most programmers will want to try it, not just front-end programmers. For these developers, the metropolis will adopt the native development of Mini programs, and they will hardly be able to learn a front-end framework of the same scale as Vue.

To sum up, from a developer's perspective, wopy adopts a Vue-like development style, which is both a strength and a weakness. The advantage is that it allows a significant number of Vue developers to transition easily, but the disadvantage is that it raises the threshold for other developers to use. Therefore, a light and easy-to-use help tool is necessary, and grace is such a tool.

Mini programs positioning

The positioning of Mini programs itself is "at your fingertips, go when you run out," solving the historical phenomenon that you have to do everything with the next APP. With Mini programs, you don't have to install too many apps, only spend a small amount of traffic to download when you use them for the first time. It can be seen that Mini programs still need to be downloaded when they are used for the first time. In order to reduce the waiting time for download and save user traffic, Mini programs set the package size to 4M, which is why "small" in Mini programs means. This limitation of WeChat determines that Mini programs are generally only used to realize core functions and will not be used as complex functions. This also determines that when developing most Mini programs, what we need is not a big frame that is strong and cool, but some simple help tools, and the positioning of grace is a delicate help tool. Many Mini programs I know, even most of them are developed natively.

Here is a summary of the main differences:

The positioning is different;grace positioning is a neat, easy-to-use Mini programs development assistance library, while wopy is a full-featured vue like framework.

Grace is easy to use, wopy has a lot of learning costs for developers who don't know Vue, and the development environment depends on many, and the configuration is more complex.

Grace is closer to native, wepy is closer to web.

Let's see what Grace does:

What Grace can do.

Let's look at the characteristics of grace:

Lightweight, compact and easy to use

Supports data responsiveness as elegant as Vue

Support automatic data update, change cache, batch update

Powerful network capabilities

Support for global event buses

Support cross-page value transfer

Support for Mixins

The main focus is exquisite, you can see that the current core functions mainly involve three aspects: data, network, events.

data

Mini programs are separated from page rendering, so there will be a lot of setData operations in development. Grace implements data responsiveness consistent with Vue to simplify this large number of explicit data updates-data can be updated directly by assignment. At the same time, in order to avoid the performance consumption caused by frequent setData, grace not only supports manual batch refresh, but also grace can automatically track the front and back background switching of the page. If the page is switched to the background, setData will not be called again, but the changes will be cached first. When the page is switched to the foreground, it will be uniformly refreshed, effectively avoiding unnecessary performance consumption.

network

Most Mini programs need to communicate with the background through http. For this reason, grace provides a powerful, flexible and good Promise API, and supports global request configuration, request/response interceptors, etc. More importantly, the Promise-style API supports ES7's async/await.

event

Mini programs are natively weak in cross-page communication, so grace provides a global event bus where you can register/trigger events on any page to communicate. Not only that, grace also implements a more friendly callback for page data return on top of the event bus.

In addition to these, grace also supports mixins, which provide a way to extend new functionality by adding features to the page globally that developers can do on their own.
