How VSCode automatically completes js code

vscode originally only had the es native api with automatic completion function, but if you use node .js or its require-related functions are relatively pitiful.

vscode can recognize typings, so typings can be used as a plug-in to expand the functions of vscode.

The specific usage method is as follows:

1. Configure jsconfig.json

Before using typings, you need to configure it in vscode Configure the file named jsconfig.json. The configuration method is very simple. Just select a js file and a small green light bulb will pop up in the lower right corner of vscode, as shown in the picture:

2. Configure jsconfig. json

Click in and the top will prompt

“Create a jsconfig.json to enable richer IntelliSense and code navigation across the entire workspace.”
Copy after login

Select create, vscode will create a jsconfig.json file, the content is roughly as follows:

{
    // See https://go.microsoft.com/fwlink/?LinkId=759670
    // for the documentation about the jsconfig.json format
    "compilerOptions": {
        "target": "es6",
        "module": "commonjs",
        "allowSyntheticDefaultImports": true
    },
    "exclude": [
        "node_modules",
        "bower_components",
        "jspm_packages",
        "tmp",
        "temp"
    ]
}
Copy after login

All required The parameters will be set for us. At this time, I am using the jsconfig generated by vscode v1.2.0. The configuration automatically generated by the lower version may be a little less than the one inside, but it does not affect it.

2. Install typings

Use npm to install typings globally

npm install -g typings
Copy after login

3. Install the syntax plug-in

Take installing node.js automatic completion as an example. Use bash or cmd in the project root directory and enter

typings install dt~node --global
Copy after login

where "dt~" means using the DefinitelyTyped type definition. vscode can recognize this definition.

After that, you can see that a new folder "typings" has appeared in the project directory
