What does _buildManifest.js in nextjs do, and can it be disabled? - next.js

We're building a site with NextJS, and noticed that in the source code of our website, we can find a _buildManifest.js file, which appears to list all pages currently defined on our site. We'd like this to not happen.
How is the _buildManifest.js file created, and what does it do?
How does it pull in the list of pages?
Is there a way disable its creation, and what breaks if we do?

We worked it out on our own, putting an update here.
It appears the build manifest is an autogenerated file that has a mapping of urls to the static JS chunk generated by webpack. This is primarily used for client-side navigation by the next/link component which, among other features, eagerly loads the JS on hover based on the href attribute.
The work is done by a webpack plugin defined here, which grabs all urls and generated JS chunks from webpack and spits out a JSON file.
As of Next v10, overriding this webpack plugin and filtering the output through an allowlist seems to work; the only observed side effect is that clicking these links must be done through a normal <a href> instead of the next/link component, which disables client-side navigation. This may lead to slightly slower page navs (no eagerly loading client-side JS on hover) but does allow for hiding the urls from a publicly visible endpoint.

Generating templated HTML documents (unrelated CSS files) from ReactJS single page app

We have recently switched to a React SPA site. From the old site, we have some documents (invoices, quotes) that we generate as HTML files that we then print as PDFs. These templates are designed by a third party and have their own separate CSS files that have nothing to do with our React SPA's CSS. After the shift to React, I added some of the templates as React-friendly modules and converted their CSS to JSS. It worked but only partially as a lot of styles are overridden by the React SPA's CSS so the results are not consistent. We don't have the resources to redo all templates from scratch and this isn't something that we should be doing anyway - ideally, we want to be able to just load in the CSS that we get from the designer and only play around with the HTML/JSX (happy to use a tool to convert CSS to JSS but no custom editing). Is there a way to somehow ignore/unload all app CSS when loading a specific page, and only use a specific CSS/JSS file (in our case makeStyles), then bring it back to normal when another page is viewed?

Is there a way to associate one stylesheet(s) for one particular template in Meteor?

The way it works now, Meteor automatically finds CSS files in the client directory and renders it without having to call it in the HTML's header tag.
However, how would I be able (if it's even remotely possible) to associate one particular CSS file or files to just one HTML page?
I recently purchased a theme for one section of my website that I didn't want to bother creating myself, since I hate doing UI for my main page myself. But when I place the CSS files of this template with the ones I have for the other template I use, one template's CSS files overwrite the other, so everything ends up looking like a huge jumbled mess.
I hope I'm being clear with my question. Is there a way to get around this?
So, if there's not a way to keep the file from being included in meteor, you could add a class to the body tag of the page you want the styles to appear in, then prepend that class to the beginning of the styles in your new stylesheet, ex: .yourBodyClass#stylehseetID, .yourBodyClass.stylesheetClass
if you put your stylesheet in the public folder, it will be treated as a static file, but then it should go in the header which is rendered by Meteor, and since Meteor is a single page app (SPA), it only has one header for the whole application.
If you need specific styles for a page, you can use some prefix for your css classes. That's probably the easiest.

In Magnolia CMS, how can each component declare its required javascript files?

I am using Magnolia CMS 5.3.4, the STK, and freemarker (FTL) template scripts.
Some components I have defined relies on specific javascript files. Right now, what I do is that I include these javascript files in the main.ftl template script. I am looking for a way to get them included only if the specific component is present on the page.
I tried to use the jsFiles property in Template Definitions, but it seems it works only for page template definition.
The jsFiles property indeed works only for pages not for components. This is because Magnolia wants to include those files in header already, rather than loading them in middle of the body when component gets rendered.
As a general practice I would anyway recommend combining your js files into one (look at for example plugin loader in resources on how this is done) and set longer time for caching such file so that browser downloads all the script just once for the whole site rather then page by page. The bigger js file you are sending over the more overhead you are cutting off from requesting separate files and better the compression of content for transport will work.

Django CMS, per page CSS Styles

I often use small, page specific CSS files for a page in Typo3 using css_select. These styles usually apply only to some special element on these pages. Putting these styles in a global file doesn't feel right.
Using css_select I can select a bunch of files that may be included into the page's header, so that it loads it's special styles.
Now I'm looking for a way to do something similar in Django CMS 3. The only built in solution I'd know is to create a new template which seems a bit excessive for a single page where an image needs to be handled a bit differently from all the others, to name just one example.
Is there a way to do this using nothing but django CMS?
If not, is there an app that would do that?
If not, how could an app extend the page admin form in such a way that this function could be added.
You could extend the page.
See http://django-cms.readthedocs.org/en/latest/extending_cms/extending_page_title.html
A good example is https://github.com/nephila/djangocms-page-meta
This the above package allows you to add additional meta tags to page header.

Best way to mange bundled script files and CDN jquery files in MVC

My default ASP.NET MVC 4 project has bundles created for JQuery and JQuery UI that is referenced in the pages.
I want to change this to use an absolute link from a CDN instead of relative on my web server.
I thought it could be as simple as just changing the url's in the bundles to point to the CDN urls. I understand why this won't work because bundles essentially bundle everything up into one file. These cases, I only have one file though.
I'm wondering. What is the best practice here. Basically, I want the code to exist in my layout or even individual pages that directs the view to load the script tags for these scrips. Then I can manage which script tags are included. The same way we do it with bundling, but I want it to work by doing the bundling and also do any other alternative script tags instead of the bundle. This way I can swap in and out depending on how I feel I want to manage my scrips at any one time. Let's say I want to add another js file to the bundle some day, or I want to include another script that will have it's script tag rendered on every page. I want a central place to do this.
Thoughts?
