Using esi includes in Nuxt 2
Question
My goal: Glue Nuxt 3 rendered code inside my old application that is written in Nuxt 2. The glue will be Varnish and using the <esi:includes
My problem: I have .vue file
<template>
<div>
<esi:include src="/from/nuxt-3-app" method="GET" />
</div>
</template>
It does work for a few seconds and *poof, disappears!
The errors I got:
1. Mismatching childNodes vs. VNodes: NodeList(15) [text, meta, text, meta, link, link, link, link, link, text, div#__nuxt, script, script, script, text] (3) [VNode, VNode, VNode...
2. [Vue warn]: The client-side rendered virtual DOM tree is not matching server-rendered content. This is likely caused by incorrect HTML markup, for example nesting block-level elements inside <p>, or missing <tbody>. Bailing hydration and performing full client-side render.
3. [Vue warn]: Unknown custom element: .... <- resolved by adding `v-pre` in <esi:include ... v-pre />
Note: They appear in order ^
What I've done:
- Use v-pre
- ignoredElements? -> I'm trying to declare it like these:
nuxt.config.js
...
Vue: {
config: {
ignoredElements: ["esi:include"]
}
}
^ but doesn't seem to work
- Wrapping
<esi:include... />with<client-only>... </client-only>("nuxt": "^2.15.8")
^ Side effect, it doesn't display or render what's inside my <esi:include
What I'm about to try:
- surrogate-control headers - Reference but seems not what I need since I already declared
do_esi=trueby default. Here's my VCL if you want to see it:
backend test {
.host = "host.docker.internal";
.port = "3101";
}
sub vcl_backend_response {
set beresp.ttl = 1s;
set beresp.do_esi = true;
}
sub vcl_recv {
unset req.http.cookie;
if (req.url ~ "^/from/nuxt-3-app") {
set req.backend_hint = test;
return (hash);
}
}
What I just want: Render what's inside the <esi:includes... /> without nuxt removing it
UPDATE :
By running $ docker exec -ti varnish-1 varnishlog -g request -q "ReqUrl eq '/from/nuxt-3-app'" , it outputs:

While I'm not a fan of doing unconditional ESI parsing, and why I still stand by the ESI content negotiation I explained in the answer you're referring to , we must first figure out why ESI isn't getting parsed at all.
Please run the following command and attach the output to your original question:
sudo varnishlog -g request -q "ReqUrl eq '/'"
My assumption is that
/is the URL of the page that contains the ESI tag. If this is not the case, please adjust the URL in the-qfilter.
Based on the varnishlog output you'll probably provide, I'll try to provide the proper solution.
Update
Based on the logs in transaction 32805 , there's something wrong with the output:
--- ESI_xmlerror ERR after 252412 ESI 1.0 <esi:bogus> element
--- ESI_xmlerror ERR after 252440 ESI 1.0 <esi:bogus> element
--- ESI_xmlerror WARN after 252479 ESI 1.0 <esi:include> lacks final '/'
--- ESI_xmlerror ERR after 252552 ESI 1.0 </esi:include> illegal end-tag
--- ESI_xmlerror ERR after 252566 ESI 1.0 <esi:bogus> element
--- ESI_xmlerror ERR after 252577 ESI 1.0 <esi:bogus> element
There's some bogus ESI content in the response of /core/journals/journalName/article/articleName/D040F6E602CB05C1AF5637F78D131964?hasAccess=0&lang=en&contentLastUpdateDate=2018-06-09T21:06:21.084Z
However, I do find it strange that transaction 32805 is complaining about this, because this is a 3-level subrequest that is not even supposed to process ESI. It looks like you're doing nested ESI.
That might be the result of processing every response with an ESI filter. Not only does it consume more CPU, it may also encounter output that it doesn't understand. Hence the error.
The only page that is supposed to contain ESI tags is /core/journals/animal-conservation-forum/article/abs/reproductive-seasonality-in-the-female-scimitarhorned-oryx-oryx-dammah/D040F6E602CB05C1AF5637F78D131964
The easy way out
The easiest solution is to tell Varnish not to enforce strict XML/xHTML rules for parsing output.
You can do this by adding the following runtime parameter to varnishd :
-p feature=+esi_disable_xml_check
There's no guarantee that it will solve your problem, but it might help.
The better solution
A better solution is to avoid nested ESI parsing when it's not needed.
As explained in https://www.varnish-software.com/developers/tutorials/example-vcl-template/#14-esi-support , you can use Surrogate-Control and Surrogate-Capability headers to negotiate ESI parsing.
That way you have full control over what kind of content is parsed for ESI tags and what not.
