FAQ
How does smart autoreload work?
We create/extend a background page or service worker in the extension with a websockets client if autoreload
is true the webpack is watch
ing, that connects to our custom websocket server.
As soon as a specific files changes the client checks how to reload the extension:
- if
manifest.json
change → full reload - if
manifest.json
dependencies change → full reload - if
_locales
change → full reload - else reload current tab & all extension views
What are vendor prefixed manifest keys?
Vendor prefixed manifest keys allow you to write one manifest.json
for multible vendors.
{
"__chrome__name": "SuperChrome",
"__firefox__name": "SuperFox",
"__edge__name": "SuperEdge",
"__opera__name": "SuperOpera",
"__safari__name": "SuperSafari"
}
if the vendor is chrome
this compiles to:
{
"name": "SuperChrome",
}
Add keys to multiple vendors by seperating them with | in the prefix
{
__chrome|opera__name: "SuperBlink"
}
if the vendor is chrome
or opera
, this compiles to:
{
"name": "SuperBlink"
}
Environment Variable Replacement in Manifest
{
"name": "__MY_ENV_VARIABLE__",
}
Would be replaced with the value of process.env.MY_ENV_VARIABLE
Why are you not using mozillas web-ext package?
webpack-webextension-plugin
should work for every browser in the same way.web-ext
only works with Chrome and Firefox. You should definitely still check it out.
