gulp Introduction

Introduction

gulp是基于Nodejs的自动任务运行器, 她能自动化地完成 javascript/coffee/sass/less/html/image/css 等文件的的测试、检查、合并、压缩、格式化、浏览器自动刷新、部署文件生成,并监听文件在改动后重复指定的这些步骤。
在实现上,她借鉴了Unix操作系统的管道(pipe)思想,前一级的输出,直接变成后一级的输入。主要呢,就是用来帮助我们更快构建。

Install node, check version command :

node -v 查看安装的nodejs版本,出现版本号,说明刚刚已正确安装nodejs。PS:未能出现版本号,请尝试注销电脑重试;
npm -v 查看npm的版本号,npm是在安装nodejs时一同安装的nodejs包管理器,那它有什么用呢?稍后解释;
cd 定位到目录,用法:cd + 路径 ;
dir 列出文件列表;
cls 清空命令提示符窗口内容。

Because the npm server is abroad, if there is no FQ and npm is particularly slow, you can consider installing the Taobao image file and install the cnpm command

npm install cnpm -g --registry=https:
Copy after login

npm installation parameter description:

-g:全局安装--save:将保存配置信息至package.json(package.json是nodejs项目配置文件);-dev:保存至package.json的devDependencies节点,不指定-dev将保存至dependencies节点;一般保存在dependencies的像这些express/ejs/body-parser等等。

npm installation, uninstallation, update, help, list Install plug-in command:

使用npm卸载插件:npm uninstall <name> [-g] [--save-删除全部插件:npm uninstall gulp-less gulp-uglify gulp-concat ……???借助rimraf:npm install rimraf -使用npm更新插件:npm update <name> [-g] [--save-更新全部插件:npm update [--save-
Copy after login

npm automatically generates the configuration file

npm init  //运行后会让你填些项目名 版本号等信息,也可以开始不填写,一路回车。
//完成后会在你的项目里生成一个package.json的配置文件。
//之后你用npm install <name> --save 就会自动保存到这个文件。
Copy after login

Install Npm After that, install gulp globally

npm install gulp -g
Copy after login

Then create a new gulpfile.js file in your project and start writing the automated pipe. You can refer to the following and finish writing. After the task that needs to be automated, type the named line directly

gulp <pipeName>
Copy after login

Python ORM Performance Benchmark: Comparing Different ORM Frameworks Python ORM Performance Benchmark: Comparing Different ORM Frameworks Mar 18, 2024 am 09:10 AM

Object-relational mapping (ORM) frameworks play a vital role in python development, they simplify data access and management by building a bridge between object and relational databases. In order to evaluate the performance of different ORM frameworks, this article will benchmark against the following popular frameworks: sqlAlchemyPeeweeDjangoORMPonyORMTortoiseORM Test Method The benchmarking uses a SQLite database containing 1 million records. The test performed the following operations on the database: Insert: Insert 10,000 new records into the table Read: Read all records in the table Update: Update a single field for all records in the table Delete: Delete all records in the table Each operation

Introduction to Yii Framework: Understand the core concepts of Yii Introduction to Yii Framework: Understand the core concepts of Yii Jun 21, 2023 am 09:39 AM

The Yii framework is a high-performance, highly scalable, and highly maintainable PHP development framework that is highly efficient and reliable when developing Web applications. The main advantage of the Yii framework is its unique features and development methods, while also integrating many practical tools and functions. The core concept of the Yii framework, the MVC pattern, Yii adopts the MVC (Model-View-Controller) pattern, which is a pattern that divides the application into three independent parts, namely the business logic processing model and the user interface presentation model.

Application of Python ORM in big data projects Application of Python ORM in big data projects Mar 18, 2024 am 09:19 AM

Object-relational mapping (ORM) is a programming technology that allows developers to use object programming languages ​​to manipulate databases without writing SQL queries directly. ORM tools in python (such as SQLAlchemy, Peewee, and DjangoORM) simplify database interaction for big data projects. Advantages Code Simplicity: ORM eliminates the need to write lengthy SQL queries, which improves code simplicity and readability. Data abstraction: ORM provides an abstraction layer that isolates application code from database implementation details, improving flexibility. Performance optimization: ORMs often use caching and batch operations to optimize database queries, thereby improving performance. Portability: ORM allows developers to

Understanding Java Design Patterns: An introduction to 7 commonly used design patterns, specific code examples are required. Java design patterns are a universal solution to software design problems. It provides a set of widely accepted design ideas and codes of conduct. Design patterns help us better organize and plan the code structure, making the code more maintainable, readable and scalable. In this article, we will introduce 7 commonly used design patterns in Java and provide corresponding code examples. Singleton Patte

Implement efficient data persistence using Python ORM Implement efficient data persistence using Python ORM Mar 18, 2024 am 09:25 AM

Object-relational mapping (ORM) is a technology that allows building a bridge between object-oriented programming languages ​​and relational databases. Using pythonORM can significantly simplify data persistence operations, thereby improving application development efficiency and maintainability. Advantages Using PythonORM has the following advantages: Reduce boilerplate code: ORM automatically generates sql queries, thereby avoiding writing a lot of boilerplate code. Simplify database interaction: ORM provides a unified interface for interacting with the database, simplifying data operations. Improve security: ORM uses parameterized queries, which can prevent security vulnerabilities such as SQL injection. Promote data consistency: ORM ensures synchronization between objects and databases and maintains data consistency. Choose ORM to have

Git is a distributed version control system that helps teams collaborate on software development. For Java developers, understanding Git is crucial because it provides a platform for managing code changes, tracking code history, and collaborating with others. Install Git for newbies (understand the basics): Install Git software and set environment variables. Create repository: Use gitinit to create a local repository. Add files: Use gitadd to add files to the staging area. Commit changes: Use gitcommit to commit changes in the staging area to the local repository. Intermediate (collaboration and version control) cloning a repository: Use gitclone to clone a local copy from a remote repository. Branching and Merging: Use branches to create isolated copies of your code
