# Build Commands Catalog
Below you'll find a list of build commands contributed by the Nativefier community. They are here as examples, to help you nativefy "complicated" apps that need a bit of elbow grease to work. We need your help to enrich it, as long as you follow these two guidelines:
1. Only add sites that require something special! No need to document here that `simplesite.com` works with a simple `nativefier simplesite.com` 🙂.
2. Please add commands with the _strict necessary_ to make an app work. For example,
- Yes to mention that `--widevine` or some `--browserwindow-options` are necessary...
- ... but don't add other flags that are pure personal preference (e.g. `--disable-dev-tools` or `--disk-cache-size`).
---
## General recipes
### Window size and position
This allows the last set window size and position to be remembered and applied
after your app is restarted. Note: PR welcome for a built-in fix for that :) .
```sh
nativefier 'https://open.google.com/'
--inject window.js
```
Note: [Inject](https://github.com/nativefier/nativefier/blob/master/API.md#inject)
the following javascript as `windows.js` to prevent the window size and position to reset.
```javascript
function storeWindowPos() {
window.localStorage.setItem('windowX', window.screenX);
window.localStorage.setItem('windowY', window.screenY);
}
window.moveTo(window.localStorage.getItem('windowX'), window.localStorage.getItem('windowY'));
setInterval(storeWindowPos, 250);
```
## Google apps
(This example documents Google Sheets, but is applicable to other Google apps,
e.g. Google Calendar)
```sh
nativefier 'https://docs.google.com/spreadsheets' \
--user-agent firefox
```
Note: lying about the User Agent is required, else Google will notice your
"Chrome" isn't a real Chrome, and will:
1. Refuse login
2. Break notifications
## Outlook
```sh
nativefier 'https://outlook.office.com/mail'
--internal-urls '.*?(outlook.live.com|outlook.office365.com).*?'
--file-download-options '{"saveAs": true}'
--browserwindow-options '{"webPreferences": { "webviewTag": true, "nodeIntegration": true, "nodeIntegrationInSubFrames": true } }'
```
Note: `--browserwindow-options` is needed to allow pop-outs when creating/editing an email.
## Udemy
```sh
nativefier 'https://www.udemy.com/'
--internal-urls '.*?udemy.*?'
--file-download-options '{"saveAs": true}'
--widevine
```
Note: most videos will work, but to play some DRMed videos you must pass `--widevine` AND [sign the app](https://github.com/nativefier/nativefier/issues/1147#issuecomment-828750362).
## HBO Max
```sh
nativefier 'https://play.hbomax.com/'
--widevine
--enable-es3-apis
&& python -m castlabs_evs.vmp sign-pkg 'name_of_the_generated_hbo_app'
```
Note: as for Udemy, `--widevine` + [app signing](https://github.com/nativefier/nativefier/issues/1147#issuecomment-828750362) is necessary.
## WhatsApp
```sh
nativefier 'https://web.whatsapp.com/'
--inject whatsapp.js
```
With this `--inject` in `whatsapp.js` (and maybe more, see [#1112](https://github.com/nativefier/nativefier/issues/1112)):
```javascript
if ('serviceWorker' in navigator) {
caches.keys().then(function (cacheNames) {
cacheNames.forEach(function (cacheName) {
caches.delete(cacheName);
});
});
}
```
## Spotify
```sh
nativefier 'https://open.spotify.com/'
--widevine
--inject spotify.js
--inject spotify.css
```
Notes:
- You might have to pass `--user-agent firefox` to circumvent Spotify's detection that your browser isn't a real Chrome. But [maybe not](https://github.com/nativefier/nativefier/issues/1195#issuecomment-855003776).
- [Inject](https://github.com/nativefier/nativefier/blob/master/API.md#inject) the following javascript as `spotify.js` to prevent "Unsupported Browser" messages.
```javascript
function dontShowBrowserNoticePage() {
const browserNotice = document.getElementById('browser-support-notice');
console.log({ browserNotice });
if (browserNotice) {
// When Spotify displays the browser notice, it's not just the notice,
// but the entire page is focused on not allowing you to proceed.
// So in this case, we hide the body element (so nothing shows)
// until our JS deletes the service worker and reload (which will actually load the player)
document.getElementsByTagName('body')[0].style.display = 'none';
}
}
function reload() {
window.location.href = window.location.href;
}
function nukeWorkers() {
dontShowBrowserNoticePage();
if ('serviceWorker' in navigator) {
caches.keys().then(function (cacheNames) {
cacheNames.forEach(function (cacheName) {
console.debug('Deleting cache', cacheName);
caches.delete(cacheName);
});
});
navigator.serviceWorker.getRegistrations().then((registrations) => {
registrations.forEach((worker) =>
worker
.unregister()
.then((u) => {
console.debug('Unregistered worker', worker);
reload();
})
.catch((e) =>
console.error('Unable to unregister worker', error, { worker }),
),
);
});
}
}
document.addEventListener('DOMContentLoaded', () => {
nukeWorkers();
});
if (document.readyState === 'interactive') {
nukeWorkers();
}
```
- It is also required to [sign the app](https://github.com/nativefier/nativefier/blob/master/API.md#widevine), or many songs will not play.
- To hide all download links (as if you were in the actual app), [inject](https://github.com/nativefier/nativefier/blob/master/API.md#inject) the following CSS as `spotify.css`:
```css
a[href='/download'] {
display: none;
}
```
