# Hello
|
|
|
|
Sample project with a simple implementation of the webxdc read and write APIs.
|
|
|
|
|
|
## Demo (no server or installation required)
|
|
|
|
1. Open `index.html` in your web browser
|
|
2. Click 'Add Peer' to open as many peers as you like
|
|
3. Type a message and press 'Send' to see the update in each peer. (For Safari you might need to check the setting under Develop > Disable Local File Restrictions.)
|
|
|
|
|
|
## Developing webxdc apps
|
|
|
|
Simply copy `webxdc.js` from this repo beside your `index.html` and you are ready to go
|
|
to **develop and test your app in most browsers.**
|
|
|
|
Bundle your app using `./create-xdc.sh your-app-name`
|
|
and **send it to your friends** 🙂

## Further Hints and Troubleshooting
|
|
|
|
|
|
### Limitations
|
|
|
|
Due to the nature of most browsers and how they scope `localStorage`,
|
|
each emulated peer will get the same `localStorage`.
|
|
|
|
To really test the storage usage of your Webxdc,
|
|
bundle the app and test it in Delta Chat directly
|
|
where all peers get their own `localStorage`.
|
|
Alternatively, use the more advanced [webxdc-dev](https://github.com/webxdc/webxdc-dev) tool.
|
|
|
|
|
|
### Type-checking and completion
|
|
|
|
If you are using VSCode you can have autocompletion and type-checking even without using TypeScript by adding these two lines to your JavaScript source files:
|
|
|
|
```js
|
|
//@ts-check
|
|
/** @typedef {import('./webxdc').Webxdc} Webxdc */
|
|
```
|
|
|
|
Without VSCode you need to install TypeScript and then run the check manually.
|
|
|
|
```sh
|
|
npm -g typescript
|
|
tsc --noEmit --allowJs --lib es2016,dom webxdc.js # to check if types and simulator are in sync
|
|
tsc --noEmit --allowJs --lib es2016,dom your_js_file.js
|
|
```
|
|
|
|
### Developing in Safari
|
|
|
|
To use the devtool in safari you need to disable the local file restrictions
|
|
under `Develop` -> `Disable Local File Restrictions`.
|
|
|
|
After doing this you can use the dev tool simulator.
|
|
|
|
Make sure to reload (`Cmd + R`) all simulator tabs/windows to apply this setting.
|
|
Without this option `Add Peer` seems to work (it opens a new instance), but **the instances will not be able to communicate**.
|
|
|
|
|
|
### Developing on Android
|
|
|
|
- install Termux
|
|
- install Python and Git in Termux
|
|
- `git clone` the devtool repo or your fork of it
|
|
- use `python -m http.server` to serve it for development using nano/vim
|
|
- when you are done, use `./create-xdc.sh` for bundling
|
|
- copy the created `.xdc` file to a location from where you can access and send it via Delta Chat
|
|
- pro tip: you can create symbolic link to a folder in the external storage
