How to install node modules from templates using npm

php editor Xigua will introduce you how to install node modules from templates through npm. npm is the package manager for Node.js, which can help us easily install, manage, upgrade and delete node modules. First, you need to make sure you have Node.js installed on your computer. Then, open a terminal or command prompt and go into your project directory. Next, initialize your project through the npm init command to generate a package.json file. In the package.json file, you can set the project name, version, author and other information. After initialization is complete, you can install the module through the npm install command. For example, if you want to install a module named lodash, you can run npm install lodash command. Once the installation is complete, you can find the installed modules in the node_modules folder of your project. This way you can use these modules in your projects. Node modules installed from templates using npm are very simple and only require a few simple steps to complete.

Question content

I am trying to use an npm installed library in a go template.

I installed the necessary three libraries via "npm install three", saved in the root folder, as shown in the picture below.

After that, I tried to import and use the three.js module as shown below, but threejs was not found.

I think there is something wrong with the file system, how can I use threejs without problems in my case?

import * as three from "/three";

class app{
    constructor(){
        // 장면
        const scene = new three.scene();

        // 카메라
        const camera = new three.perspectivecamera(75, window.innerwidth / window.innerheight, 0.1, 1000);

        // 렌더러
        const renderer = new three.webglrenderer();
        renderer.setsize(window.innerwidth, window.innerheight);

        document.body.appendchild(renderer.domelement);

        renderer.render(scene, camera);
    }
}

window.onload = function(){
    new app();
}

mistake

Import * as three from "/三";

http://localhost:8081/three net::err_aborted 404 (not found)

Import * from "three" as three;

uncaught typeerror: failed to resolve module specifier "three". relative references must start with either "/", "./", or "../".

e.static("/node", "node_modules")

in main.go

Import * as three from "/node/node_modules/三/build/third.module.js";

GET http://localhost:8081/node/three/builld/three.module.js net::ERR_ABORTED 404 (Not Found)

Solution

<script type="importmap">
    {
        "imports": {
            "three": "/node/three/build/three.module.js"
        }
    }
</script>
