Today's young people can really play, more and more new things come out, and more and more fun things are popular.
It's like the blind box of the recent fire stall.
Seriously, I didn't know what a blind box was before.
In front of me, a fan asked me to develop a small blind box program. Therefore, I went to the stall and bought some blind boxes to play!
It's fun. It's fun.
Then I went to the Internet. Many companies are pushing blind box app s or small programs.
For example, Netease's blind box applet, I have been updating articles on csdn and often receive notifications of their blind box applet.
Here is what I developed:
The following is a brief introduction to the small program developed. There are many core areas that may not be open.

1, Technical realization:
Because the customer doesn't have technical requirements, it's developed according to the technology I'm used to. It doesn't matter whether it's the latest or not.
Background framework: SpringBoot,
Mysql used in the database,
The back-end pages are developed using Vue,
Redis for caching,
The search engine adopts elastic search,
ORM layer framework: MyBatis,
Connection pool: Druid,
Sub database and sub table: MyCat,
Permissions: Spring security,
Code quality check: sonar.

-- ----------------------------4, Market positioning:
What is the biggest market?
The elderly should be healthy, women should be beautiful, and men should make money!
The target customers are women. The products are cosmetic products and high-end cosmetic products.
My wife often uses cosmetics. She went to a certain place to search. A small bottle of make-up water is the money for a pair of sneakers. I love it very much. nnd, I have worn a pair of sneakers for 7 years. I saw it split.
More than 100 million a month.
The customer's choice of the market is absolutely no problem, and the game is very fun. I used to play CF's lucky draw. I don't know how many rounds I played.
So the customer told me that they had to raise 2000w in the first round. If it happened, there would be a play.
The market for cosmetics is too big.
By the way, if you want to ask me for development, I want to declare the following:
We're not interested in the market at all. We're just developing! So you ask me to develop, I don't join your partnership, I just develop, and I don't have to draw cakes for me. Just give me the cost of development.
To put it bluntly, I just want to develop it for free. Every once in a while, someone always gives me picture cakes. I'm sorry, I have a bad stomach recently and can't digest big cakes.
But entrepreneurship is risky. I took a lot of development work in front of me. Among the many entrepreneurial products, only one person succeeded.
A Chinese dating website for an international student.
When the weather, geography and people were right, it suddenly became popular, and the annual profit reached 500w.
Most of the other 99% developed products are gg.
The idea of some products is very good and the market is also very good, but the promotion needs a great cost. Ordinary people can't afford to play.
The worst boss, we developed a labor market APP for him, and the market is huge. The boss smashed 300w promotion fee hopefully, and the development fee smashed 20w for us.
Unfortunately, all the money was lost in the end.
Finally, the reasons for the investigation for a long time, so that the boss is very depressed:
Migrant workers generally don't like to use app s. If the process used is complex, it will not be used. And promotion requires constant money.
The boss sprayed blood directly
5, Xiao Meng suggested:
With a good idea, we can develop it, but
Successful products need luck, capital injection and rapid occupation.
Ali tiktok has also done social software, and Tencent has also done an electronic shopping mall.
A successful product needs the right time, the right place and the right people.
In general, the product is hard enough. Only when it is put on the market and let the user experience is the king. As for other idea s, sometimes it's bullshit.
I'm Xiao Meng, sharing all kinds of project experience and interview materials.
Let's make progress together.
