caddy2-html-injection-plugin

Originally released on https://github.com/sjtug/caddy2-filter

Usage

Only the listed fields are supported.

Caddyfile:

# Add this block in top-level settings:
{
	order injection after encode
}

injection {
    # File to inject as inline text
    inject <file to inject>
    # Where to inject
    before "</body>"
    # Only process content_type matching this regex
    content_type <regexp pattern>
}

# If you are using reverse_proxy, you may need to add this to its config to ensure
# reverse_proxy returns uncompressed body:

header_up -Accept-Encoding

JSON config (under apps › http › servers › routes › handle)

{
    "handler": "injection",
    "path": "<regexp>",
    "inject": "<file>",
    "before": "<suffix>",
    "content_type": "<regexp>"
}
