Configuring Webpack For Manually Added Files

Simple question about jquery and webpack, I have downloaded jquery.js then added into app.js these lines import './jquery'; import './bootstrap'; My webpack.config entry line entr

Solution 1:

Step 1 :

In general, Webpack is a module bundler.

It allows bundling your own modules (require("./my-module.js")) as well as thirdparty modules (require("bootstrap"))

In your case, that would mean you dont have to download the jquery and bootstrap files yourself. Update your package.json to include the required jquery and bootstrap modules. NPM will take care of getting them and webpack will do the bundling from the node_modules files.

Step 2 :

In general, webpack needs and entry point and output locations. Thats the minimal config it needs.

Once you have an entry point, webpack still needs to know what dependencies your code needs. Be it your own modules or thirdparty modules (maintained with npm). That is where the require("module-name-or-path") or import "module-name-or-path" comes into picture. What that means is that you need to make sure your entry script has all the required dependencies mentioned either in the same file or in the dependent modules.

To give more insight, webpack looks at the entry point and will build the dependency graph. It will read all that require() or import and pulls in all required modules. It then bundles it.

In your case, the entry script can include the require statements for jquery and bootstrap npm modules (i.e. thirdparty)

In case, you still need clarity, feel free to go through the code here. Especially take a look at src/entry.js

Note : Bootstrap needs fonts and images as well. The code in repository above, takes care of them too. All the magic done by webpack!
