This article mainly explains "becoming an excellent back-end development engineer step by step". Friends who are interested might as well take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "to become an excellent back-end development engineer step by step".

Learn a programming language

There are many programming languages, and for beginners who are just starting out for back-end development, I suggest you start with any scripting language, because scripting languages can solve many practical problems and get you started quickly. If you have some front-end knowledge, then I recommend you start with NodeJs, because they have the same blood as JS.

If you are already doing back-end development and are familiar with a scripting language, it is recommended that you do not choose another scripting language, for example, if you are already using PHP or Node.js, do not use Python or Ruby, but try Erlang or Golang. It will certainly help you broaden your mind and broaden your horizons.

Practice frequently

There is no better way to learn than to practice. Once you begin to learn a language and have some basic understanding of its concepts, you can try to use them to make small applications. The application does not need to be big, but it is enough to use all the knowledge you have learned.

Learning package Manager

After you have mastered the basics of a programming language, you can learn to use the package manager. The package manager can help you use external libraries in your application and distribute your libraries for use by others, and you will find that open source is really wonderful.

If the language you choose is PHP, you can learn Composer, if it is Node.js, you can learn NPM or Yarn, if it is Python, you can learn Pip, and if Ruby, you can learn RubyGems. No matter what you choose, the package manager will make it easier for you to develop programs.

Learning language standard

Each programming language has its own recommended writing standards and best practices. For example, PHP has PHP-FIG and PSR. With Node.js, there are many different community-driven guides, as well as other languages. The writing rules of the specification can make your program more elegant.

Learning test

Any software development is inseparable from testing, you need to know how to carry out application unit testing and integration testing, you need to learn TDD development, you need to master at least one testing method, a robust program without bug is a good program.

Learning database

Database is a topic that can never be developed without. No matter what software you do, whether it is a website or APP, database is a technology stack that you can not do without.

You can learn about relational databases at first, because they are databases that you often use.

You need to know how to operate the database, how to create a table structure, how to add, delete, change and query data, and how to optimize queries.

Learning framework

In the process of the development of any programming language, there will be a variety of frameworks, some are bloated, some are simple, some are elegant, some are very efficient, no matter what kind of framework, we can learn more from them.

At first, you can try to learn and use a framework, learn its basic use, then learn to understand and master its design patterns, and then try to understand its underlying operating mechanism. finally, I hope you can develop your own framework.

Learning cache

With the increasing amount of data, with the requirement of high concurrency and the reduction of memory cost, memory database has increasingly become a basic skill that developers have to master.

You can learn caching techniques such as memcache and redis, and try to integrate them in applications. Once you learn to master them, you will find that the corresponding speed of your application will make a qualitative leap.

Learn to create an API

Whether it is Mini Program, or app background development, we can not do without the interface, and the interface is what we call API, by learning and using API, you will find that the separation of the front and rear is so easy and simple, and the original background development can also be so easy.

Learning rights management

Permissions are the guarantee of application security, and only with reasonable permissions can our application run safely.

You can first learn design ideas such as acl,rbac, and then you can learn authentication technologies such as oauth,jwt.

Message middleware

When your business needs to deal with large-scale data, when you want to do distributed business, middleware is a technology that you can never leave.

At this time, you can learn rabbitmq and kafka. After learning these two message middleware, you will find that the emergence of the original message queue makes your development.

There are more scientific layering.

Search technology

For massive data retrieval, you need some more in-depth technology, at this time, you can learn elasticsearch and try to use it in data retrieval.

Data retrieval itself is not a complex matter, but when your data becomes massive, you will find that search is not a simple thing.

Learn to use Docker

The disunity between the production environment and the test environment has always been a worry for developers, and the emergence of docker has completely solved the developer's mind. With docker, your production environment can become exactly the same as the test environment, and you may no longer be able to use environmental problems as the reason for your application of BUG.

When you master container technologies such as docker, you will find that the development and deployment of programs can be so easy.

Learning Web Server

Whether it's nginx or apache, or websphere and tomcat, you need to be proficient in at least one of them, and you need to learn to understand its source code and how to optimize configuration based on your business.

Learning socket

Once your application is related to the network, you can't do without socket technology, which is the most important communication protocol in Internet applications.

Network applications are delivered not only through http protocol, but also need to use socket protocol. We need to understand the underlying principles of socket and learn how to deal with network communication.

Learning GraphQL

Learn how to use GraphQL to make API. Learn how it differs from REST and why it is called REST 2.0.

You need to know that the emergence of a technology must have its technical background, and understanding its background will be of great help to you to master it.

At this point, I believe you have a deeper understanding of "becoming an excellent back-end development engineer step by step". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
