Building the behavior burial site of the basic front-end independently based on Angular4

at present, the project business is progressing steadily, and there is some independent time to learn. I have read some articles on front-end burying points, and I also have a theoretical understanding of the three schemes of manual burying points / visual burying points / no burial points. However, there are still some problems in building a simple burial point function.
artificial burial will not be considered for the time being, because what we are going to build this time is based on the record of the behavior and operation of the whole platform. I don"t know how to start the development. I would like to ask you all here, thank you very much
