root-config | The root config for polyglot microfrontends | Single Page Application library

I've been experimenting with single-spa for a while, and understand the basics of the developer experience. Create a parcel, yarn start on a unique port, add the reference to the import map declaration, and so on. The challenge with this is that as my root-config accrues more and more modules managing ports and import-maps starts to get tedious. What I want is to publish these modules to a central repository and load them from there (e.g., http://someserver.com/repository/moduleA/myorg-modulea.js, etc.).

I was recently introduced to localstack and started thinking maybe a local S3 bucket would serve for this. I have a configuration where builds (yarn build) are automatically published to an s3 bucket running on localstack. But when I try to load the root config index.html from the bucket I get the following JS error:

I've created a few apps that follow the same pattern as the react-microfrontend projects listed on the Single-spa examples page. However, these examples are not using TypeScript.

I am receiving a TS error when App2 tries to import a function that exists in App1, because App2 is unable to find the typings for the App1 object. And this makes sense to me, since the importmap.json that is referenced in the index.html file of the root-config project only has a URL listed for the .js file of each microfrontend. I really don't want to add @ts-ignore statements everywhere, and I also don't want to do cross-app communication without being type safe.

An example of what I'm referring to:

This file in the Planets app references the Button component from the Styleguide app. I am unable to build this unless I place a @ts-ignore on the line before the import statement, because my Planets app cannot find the type declarations for Styleguide.

I am very new to import maps and SystemJS in general, so if anyone could point me in the right direction, I'd appreciate it. I've actually gone through the trouble of building my Styleguide as a regular npm library and just including it as a dependency in the Planets package.json file... which kind of defeats the whole purpose of using Single-spa in the first place.

I am getting a Clang compiler error when compiling ROOT script:

~/root_install/include/ROOT/RStringView.hxx:32:4: error: redefinition of 'basic_string_view' as different kind of symbol using basic_string_view = ::std::experimental::basic_string_view<_CharT,_Traits>;
/usr/include/c++/9/string_view:90:11: note: previous definition is here
class basic_string_view

This is the problematic code in ROOT library:

Apparently, CERN's "Root" software is compatible (as of version 6.12) with C++17. However, I have been completely unable to get this to work with the newest version (6.20) and all previous questions I found on this topic are from a few years ago.

Does anyone with Root experience know if there is a particular compiler option to get it to work with C++17?

Examples of errors I get when trying to compile a trivial "Hello world" program:

• The following is (I think) due to the "TFile.h" header implicitly loading "TString.h":

I want to create a plot with a TF1 function in my C++ program. For compiling I use

g++ *.cpp $(root-config --cflags --glibs)

and that works just fine.

But when I do ./a.out afterwars it just won't show me the canvas it created (it says in the shell that a canvas C1 was created).

I already tried using a dummy with cin >> dummy but that doesn't work either

I have a structure as follows:

I know there are some similar questions, here Invoking C compiler using Python subprocess command and subprocess, invoke C-program from within Python but I believe my question is in some sense different.

I need to compile a c++ program which uses some ROOT libraries so I need to add some flags and link some libraries for the compilation. Therefore my compilation line on the normal shell is:

I'm using a Makefile for setting up the environment needed for mo code. I'm just learning about parallelizing and would appreciate your help.

I have a big problem to install rootpy. When I try this command:
