tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.
@nimiq/browser-warning

Readme
Javascipt, CSS and a html snippet to display a warning in case of unsupported browsers, private mode or disabled Javascript.
yarn add @nimiq/browser-warning
This is no modular package you can import. Instead:
<script type="text/javascript" src="browser-warning.js" defer></script>
in
front of all other scripts which may execute, especially your app's main entry point. If your other scripts are not
deferred, also remove the defer
attribute on browser-warning.js
.window.hasBrowserWarning === true
and stop execution in that case.@nimiq/browser-warning
to
compilerOptions.types
in your tsconfig.json
.You can define a callback window.onBrowserWarning
that gets called in case of a browser warning with the warning type
and a config object:
Parameter | Type |
---|---|
warningType | 'web-view' / 'browser-outdated' / 'no-local-storage' / 'private-mode' |
warningConfig.headline | string |
warningConfig.message | string |
warningConfig.hasShareButton | boolean |
warningConfig.shareUrl | string |
warningConfig.useNativeShare | boolean |
warningConfig.shareInstructions | string |
It can then optionally return a configuration object that overwrites a subset or all of the configuration properties.
Note that window.onBrowserWarning
needs to be defined before browser-warning.js
is executed. This is therefore an
exception to the rule stated in the previous section.
Note that the script that defines window.onBrowserWarning
must be written in old-fashioned Javascript to not fail
with syntax errors in old browsers which would prevent us from being able to display a warning in old browsers.
Contributions are welcome! To build the code yourself run
yarn build
which minifies the code with Google's closure compiler. We are compiling with the compiler's SIMPLE
compilation level
as the ADVANCED
level does not result in significantly smaller files for this lib, especially when comparing gzipped
size. You therefore do not need to mind the special precautions that are required for the ADVANCED
level.
Code does however need to be written in old-fashioned javascript to be compatible with old browsers. The closure compiler will warn you if your code is not valid ES3.
