Overriding callbackOptions while keeping default behavior #1766
Description
You can override the callbackOptions and provide additional logic to run before/after installing the Slack app.
We use it to send a welcome message to the installing user after a succesfull installation. However, you need to manually end the response using res.end:
callbackOptions: {
success: (installation, _options, _req, res) => {
app.client.chat.postMessage({
token: installation.bot.token,
channel: installation.user.id,
text: 'Welcome to my app!'
});
res.end('Success!');
}
}
This example just displays a basic message, rather than the default Slack page that displays when no logic is provided, that also automatically redirects to the Slack app, along with a magic link:
Requirements
I want the callback to provide a default, that you can call after executing your custom logic, which will show the same page but will still allow me to run my logic. The Python SDK already has this; see this PR.
