Angular builds question - Changes in static DSpace content

[Petros Grammatikopoulos]

Greetings

As I am not entirely familiar with Angular as a framework,

and most particularly the build process of the production environment of the DSpace 7 Angular frontend,

I have an inquiry for DSpace 7.0:

When I make a change in a static content file, let's say the end-user-agreement page for example, do I have to redo the whole production build for the change to be applied to the frontend (yarn run build:prod) or is there a faster way?

The limited resources I currently have in setting up this project (time, people) do not allow me to look through setting up some sort of developer environment, as I briefly saw it mentioned in the wiki. I am setting this up as a side-project.

I would like to know if there's a faster way for straight-to-production changes like the one mentioned above, but without messing about too much -if at all- with the default configs and buildfiles.

Currently a whole frontend build takes 10 minutes and is perceived as downtime by endusers, so that's what I'm trying to avoid for mere static page content changes...

Thank you in advance and I really appreciate your time if you have a "shortcut" for this procedure in mind.

Hi Petros,

Apologies for the delay in answering your question... After seeing your question, we realized that our Installation Documentation was recommending a setup which results in​ this issue you are experiencing.

Simply put, if you run your UI from the build location ([dspace-angular]/dist), then anytime you rebuild, then the running UI will be unavailable during the rebuild process. This is what you are noticing.

However, if you move the built UI to a different location & run it from there, then you are able to rebuild the UI at any time without impacting the running UI.  This minimizes downtime in Production scenarios.  Unfortunately, though, the build process of 7.0 & 7.1 made this setup much harder to achieve. So, we recommend you first upgrade to 7.2.

Our 7.2 Installation Docs have been updated now to recommend running your UI from a different "deployment" directory.  See https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-FrontendInstallation

If you have further questions, let us know on this list.

Tim
