Viewed 85k times. But now I have about two dozen "imports" in other files giving me the same error. Most of what I've found for solutions don't seem to apply to straight Node. Hi, having the same problem right now. Could you also share your dependencies? Maybe even a diff before and after your update. I could check against mine to see if we can find similar packages which might cause the trouble. I just replaced all the "imports" with "requires" and all is well now. Dumb but it wasn't worth the effort to figure it out right now.

I will update the original with dependencies, though.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The old versions of JavaScript had no import, include, or require, so many different approaches to this problem have been developed.

To enable "ESM" vs. Similarly, modules written with Node. Check the current support at caniuse. There is no need to use Node. The older CJS module style, still widely used in Node.

There are other ways for JavaScript to include external JavaScript contents in browsers that do not require preprocessing. You could load an additional script with an AJAX call and then use eval to run it.

This is the most straightforward way, but it is limited to your domain because of the JavaScript sandbox security model. Using eval also opens the door to bugs, hacks and security issues. Like Dynamic Imports you can load one or many scripts with a fetch call using promises to control order of execution for script dependencies using the Fetch Inject library:. The jQuery library provides loading functionality in one line :.

To avoid the overhead of jQuery, this is an ideal solution. The script can even reside on a different server. Furthermore, the browser evaluates the code. Now, there is a big issue you must know about. Doing that implies that you remotely load the code.

ES6 Modules

Modern web browsers will load the file and keep executing your current script because they load everything asynchronously to improve performance. This applies to both the jQuery method and the manual dynamic script loading method. It means that if you use these tricks directly, you won't be able to use your newly loaded code the next line after you asked it to be loadedbecause it will be still loading.

Well, you can use the hack the author suggests in the link I gave you. In summary, for people in a hurry, he uses an event to run a callback function when the script is loaded. So you can put all the code using the remote library in the callback function. For example:. Note that the script may execute after the DOM has loaded, or before, depending on the browser and whether you included the line script.

There's a great article on Javascript loading in general which discusses this. If anyone is looking for something more advanced, try out RequireJS. You'll get added benefits such as dependency management, better concurrency, and avoid duplication that is, retrieving a script more than once. You can write your JavaScript files in "modules" and then reference them as dependencies in other scripts. Or you can use RequireJS as a simple "go get this script" solution.

RequireJS loads plain JavaScript files as well as more defined modules. It is optimized for in-browser use, including in a Web Worker, but it can be used in other JavaScript environments, like Rhino and Node.Supported extensions: jsjsxes6jsmmjs. The most traditional file type for web bundlers is JavaScript. It also supports dynamic import function syntax to load modules asynchronously, which is discussed in the Code Splitting section.

Dynamic imports can also import modules from URLs. You can also import non-JavaScript assets from a JavaScript file, e. When you import one of these files, it is not inlined as in some other bundlers.

Instead, it is placed in a separate bundle e. Other asset types export a URL to the output file in the JavaScript bundle so you can reference them in your code.

Babel is a popular transpiler for JavaScript, with a large plugin ecosystem. Using Babel with Parcel works the same way as using it standalone or with other bundlers. For the browser target it utilises browserslistthe target browserlist can be defined in package. For the node target, Parcel uses the engines. Flow is a popular static type checker for JavaScript. Parcel will automatically install the required Babel config to strip the Flow types from the compiled output, so there's nothing you have to worry about except editor integrations or supporting Absolute Path module resolution with.

The name parameter is the name of the "module object" which will be used as a kind of namespace to refer to the exports. Below are examples to clarify the syntax. Here, accessing the exports means using the module name "myModule" in this case as a namespace. For example, if the module imported above includes an export doAllTheAmazingThingsyou would call it like this:. Given an object or value named myExport which has been exported from the module my-module either implicitly because the entire module is exported or explicitly using the export statementthis inserts myExport into the current scope.

You can rename an export when importing it. For example, this inserts shortName into the current scope. Import an entire module for side effects only, without importing anything. This runs the module's global code, but doesn't actually import any values. If your project uses packages that export ESM, you can also import them for side effects only.

This will run the code in the package entry point file and any files it imports only.

It is possible to have a default export whether it is an object, a function, a class, etc. The import statement may then be used to import such defaults. It is also possible to use the default syntax with the ones seen above namespace imports or named imports. In such cases, the default import will have to be declared first. For instance:. You need to destructure and rename the "default" key from the returned object. The standard import syntax is static and will always result in all code in the imported module being evaluated at load time.

The following are some reasons why you might need to use dynamic import:. Use dynamic import only when necessary. When used this way, it returns a promise. This example shows how to load functionality on to a page based on a user action, in this case a button click, and then call a function within that module. This is not the only way to implement this functionality. The import function also supports await.
