+# Without a Bundler
+
+[View full source code][code]
+
+[code]: https://github.com/rustwasm/wasm-bindgen/tree/master/examples/without-a-bundler
+
+This example shows how the `--target web` flag can be used load code in a
+browser directly. For this deployment strategy bundlers like Webpack are not
+required. For more information on deployment see the [dedicated
+documentation][deployment].
+
+First, you'll need to add `web-sys` to your Cargo.toml.
+```toml
+[dependencies.web-sys]
+version = "0.3.4"
+features = [
+  'Document',
+  'Element',
+  'HtmlElement',
+  'Node',
+  'Window',
+]
+```
+
+Then, let's take a look at the code and see how when we're using `--target web`
+we're not actually losing any functionality!
+
+```rust
+{{#include ../../../examples/without-a-bundler/src/lib.rs}}
+```
+
+Otherwise the rest of the deployment magic happens in `index.html`:
+
+```html
+{{#include ../../../examples/without-a-bundler/index.html}}
+```
+
+And that's it! Be sure to read up on the [deployment options][deployment] to see
+what it means to deploy without a bundler.

+## Using the older `--target no-modules`
+
+[View full source code][code-no-modules]
+
+[code-no-modules]: https://github.com/rustwasm/wasm-bindgen/tree/master/examples/without-a-bundler-no-modules
+
+The older version of using `wasm-bindgen` without a bundler is to use the
+`--target no-modules` flag to the `wasm-bindgen` CLI.
+
+While similar to the newer `--target web`, the `--target no-modules` flag has a
+few caveats:
+
+* It does not support [local JS snippets][snippets]
+* It does not generate an ES module
+
+With that in mind the main difference is how the wasm/JS code is loaded, and
+here's an example of loading the output of `wasm-pack` for the same module as
+above.

+```html
+{{#include ../../../examples/without-a-bundler-no-modules/index.html}}
