How to set local when running vue locally

Vue is a popular JavaScript framework that can be used to build modern web applications. In Vue project development, it is particularly important to run it locally to improve development efficiency and test quality. This article will introduce the setup and configuration methods of Vue running locally and related precautions.

First, in order to run the Vue project, we need to use Node.js and the npm package manager. If you have not installed these two tools, please go to the official website to download and install them.

After the installation is complete, we need to enter the root directory of the Vue project on the command line. In that directory, we need to install the dependencies required by Vue using the following command:

npm install

Next, we can use the following command to start the development server:

npm run serve

This command will start a A local development server that you can use to access your Vue application in your local browser. By default, the server will run on localhost:8080 port. You can access this port in your browser to access your Vue application.

If you wish to set up the server to run on a different port or IP address, please use the following command:

npm run serve -- --port [port] --host [host]

Please change [port] and [host] to the port and [host] you wish to use. IP address.

There are also some other commands that can be used. For example, you can build a Vue application using the following command:

npm run build

This command will build the static files and save them in the /dist directory. You can upload files in this directory to a web server to deploy your Vue application.

If you want to check whether your code complies with the specification, please use the following command:

npm run lint

This command will perform a syntax check on your code and provide possible fixes.

Finally, please note that when using a Vue application, you may need to access other server resources, such as the REST API. At this time, due to security issues, the browser will prohibit access to resources outside the same origin. To avoid this problem, you can use the CORS (Cross-Origin Resource Sharing) mechanism. For example, you can set the appropriate CORS headers on the server side to allow your Vue application to access the API. Alternatively, you can use Vue's axios library to easily handle cross-domain requests.

To summarize, Vue running locally is very easy to set up and configure. By using npm and a few simple commands, you can run Vue applications in your local development environment. At the same time, please ensure that your Vue application can access the API and that the application complies with security specifications. Have fun developing with Vue!
