# Parity Dapps (JS-glue)
Code generator to simplify creating a built-in Parity Dapp
# How to create new builtin Dapp.
1. Clone this repository.
```bash
$ git clone https://github.com/paritytech/parity.git
```
1. Create a new directory for your Dapp. (`./myapp`)
```bash
$ mkdir -p ./parity/dapps/myapp/src/web
```
1. Copy your frontend files to `./dapps/myapp/src/web` (bundled ones)
```bash
$ cp -r ./myapp-src/* ./parity/dapps/myapp/src/web
```
1. Instead of creating `web3` in your app. Load (as the first script tag in `head`):
```html
<script src="/parity-utils/inject.js"></script>
```
The `inject.js` script will create global `web3` instance with proper provider that should be used by your dapp.
1. Create `./parity/dapps/myapp/Cargo.toml` with you apps details. See example here: [parity-status Cargo.toml](https://github.com/paritytech/parity-ui/blob/master/status/Cargo.toml).
```bash
$ git clone https://github.com/paritytech/parity-ui.git
$ cd ./parity-ui/

# How to include your Dapp into `Parity`?
1. Edit `dapps/Cargo.toml` and add dependency to your application (it can be optional)
```toml
# Use git repo and version
parity-dapps-myapp = { path="./myapp" }
```
1. Edit `dapps/src/apps.rs` and add your application to `all_pages` (if it's optional you need to specify two functions - see `parity-dapps-wallet` example)
1. Compile parity.
```bash
$ cargo build --release # While inside `parity`
```
1. Commit the results.
```bash
$ git add myapp && git commit -am "My first Parity Dapp".
```
