In practical terms, boilerplate code is the stuff you cut-n-paste all over the place. Often it'll be things like a module header, plus some standard/required declarations (every module must declare a logger, every module must declare variables for its name and revision, etc.) On my current project, we're writing message handlers and they all have the same structure (read a message, validate it, process it) and to eliminate dependencies among the handlers we didn't want to have them all inherit from a base class, so we came up with a boilerplate skeleton. It declared all the routine variables, the standard methods, exception handling framework — all a developer had to do was add the code specific to the message being handled. It would have been quick & easy to use, but then we found out we were getting our message definitions in a spreadsheet (which used a boilerplate format), so we wound up just writing a code generator to emit 90% of the code (including the unit tests).

Boilerplate definition is becoming more global in many other programming languages nowadays. It comes from OOP and hybrid languages that have become OOP and were before procedual have now the same goal to keep repeating the code you build with a model/template/class/object hence why they adapt this term. You make a template and the only things you do for each instance of a template are the parameters to individualize an object this part is what we call boilerplate. You simply re-use the code you made a template of, just with different parameters.

样板文件是一种写作单元，可以不作任何更改地反复使用。通过扩展，这种思想有时应用于可重用编程，如“样板代码”

软件开发中的样板对不同的人有不同的含义，但通常是指反复使用的代码块。

在MEAN栈开发中，这个术语指的是通过使用模板来生成代码。它比从头开始手动编码整个应用程序更容易，它提供了代码块的一致性和更少的错误，因为它是干净的，经过测试和验证的代码，而且它是开源的，所以它不断更新或修复，因此它在使用框架或代码生成器时节省了大量时间。有关MEAN stack的更多信息，请点击这里。

“样板代码”是任何看似重复的代码，它们一次又一次地出现，以获得一些看起来应该简单得多的结果。

这是一个主观的定义。
