Flakes is one of the most significant changes the nix project has ever seen.[^2]
In simple terms, if you've worked with some JavaScript/Go/Rust/Python, you should be familiar with files like `package.json`/`go.mod`/`Cargo.toml`/`pyproject.toml`. In these programming languages, these files are used to describe the dependencies between software packages and how to build projects.
Similarly, the package managers in these programming languages also use files like `package-lock.json`/`go.sum`/`Cargo.lock`/`poetry.lock` to lock the versions of dependencies, ensuring the reproducibility of projects.
Flakes borrow ideas from these package managers to enhance the reproducibility, composability, and usability of the Nix ecosystem.
Flakes introduce `flake.nix`, similar to `package.json`, to describe the dependencies between Nix packages and how to build projects.
Additionally, it provides `flake.lock`, akin to `package-lock.json`, to lock the versions of dependencies, ensuring project reproducibility.
## A Word of Caution about Flakes <Badge type="danger" text="caution" />
The benefits of Flakes are evident, and the entire NixOS community has embraced it wholeheartedly. Currently, more than half of the users utilize Flakes[^3], providing assurance that Flakes will not be deprecated.

Flakes 特性是 Nix 项目中最有意义的变化之一。[^2]
简单的说，如果你写过点 JavaScript/Go/Rust/Python，那你应该对 `package.json`/`go.mod`/`Cargo.toml`/`pyproject.toml` 这些文件不陌生，
在这些编程语言中，这些文件用来描述软件包之间的依赖关系，以及如何构建项目。
同样的，这些编程语言的包管理器还通过 `package-lock.json`/`go.sum`/`Cargo.lock`/`poetry.lock` 这些文件来锁定依赖的版本，以保证项目的可复现性。
Flakes 就是从上述这类编程语言的包管理器中借鉴了一些思想，以提高 Nix 生态系统中的可复现性、可组合性和可用性。
Flakes 提供了 `flake.nix`，它类似 `package.json`，用来描述 Nix 包之间的依赖关系，以及如何构建项目。
同时它还提供了 `flake.lock`，这是一个类似 `package-lock.json` 的文件，用来锁定依赖的版本，以保证项目的可复现性。
## 注意事项 <Badge type="danger" text="caution" />
Flakes 带来的好处是显而易见的，整个 NixOS 社区都很喜欢它，目前超过半数的用户已经在大量使用 Flakes[^3]，因此我们可以相当确定 Flakes 不会被废弃。
