Configuration
As of v3.3.0, each eslint-plugin-react-perf rule supports configuration to control whether native elements (lower case first letter React components) are ignored.
With this configuration, all native elements are ignored for this rule:
{
"react-perf/jsx-no-new-object-as-prop": [
"error",
{
"nativeAllowList": "all"
}
]
}
With this configuration, the "style" attribute is ignored for native elements for this rule:
{
"react-perf/jsx-no-new-object-as-prop": [
"error",
{
"nativeAllowList": ["style"]
}
]
}
