First of all, it is necessary to determine the requirements of the applet to be developed, including what functions are required, what needs to be used for, in what scenarios, and finally determine the specific required functions.
The second step is to make a map according to the customer's needs, which can perfectly present all the functions required by the applet.
The next step is the UI design. The UI designer will design an interface diagram according to the customer's needs. The entire UI can intuitively see the detailed functions of the applet.
The fourth step is that the little brother of the programmer has played his part. After the UI is confirmed, he starts to write the front end of the program. After writing the front end, he continues to write the back end. After the backend is finished, continue to write the frontend. Just like this, the frontend and backend are repeated repeatedly. Some of them have hundreds or even thousands of files, and it takes a month or even a few months to write. Finish.
After the program is completed, there is the last step, which is program testing. All the source codes of the software are stored in the server, and each programmer copies these files in his own computer. When ready, he submits the changed files to the server, and then tests whether there are bugs in the whole process, and any errors occur. A small problem will cause the software to fail to open, and then return to the programmer to continue to modify, and then test after modification, until the program is running normally. Although programmers write carefully, there are always some code problems, such as misspelled words. These problems are usually called bugs. Even if the software is already in use, programmers need to constantly fix bugs to improve it, so the software will be updated regularly Or upgrade to a newer version. So that's why software companies have maintenance fees. Because the program maintenance is also very troublesome and hard work.
This is why some software requires thousands, tens of thousands, or even millions of projects. It is directly related to the difficulty of developing small programs and the length of time for function development, including later maintenance functions. The above is how the mini-program discussed today is developed, please feel free to consult.
