skip to Main Content

I have a frontend app that is using module federation architecture. It contains one shell application and 3 micro-frontends. I built container for each of these 4 apps. When I run these containers and go to chrome, open my shell it works just fine. I then try to navigate to any of the other applications via my navbar but I get the following errors:

When inspecting network, remoteEntry.mjs is loaded:

I am able to open and examine it:

Also, i tried changing my registry HKEY_CLASSES_ROOT.jsContent Type to text/javascript but it didn’t seem to work.

Any help would be much appreciated as am new to the module federation architecture as well as dockers.

Edit: I am using Nginx server with this config:

 events{}
 http {
    include /etc/nginx/mime.types;
    server {
        listen 80;
        add_header Access-Control-Allow-Origin *;
        server_name localhost;
        root /usr/share/nginx/html;
        index index.html;
        location / {
            try_files $uri $uri/ /index.html;
        }
    }
}

Here is my Dockerfile for one of the micro-frontends:

FROM node:latest as node
WORKDIR /app
COPY . .


RUN npm install -g @nrwl/cli
RUN npm install --force
RUN npx nx build graphs --configuration=production

#stage 2
FROM nginx:alpine
COPY ./apps/graphs/nginx.conf /etc/nginx/nginx.conf
COPY --from=node app/dist/apps/graphs /usr/share/nginx/html

Edit: I tried adding

types 
        {
            application/javascript mjs;
        }

to my nginx config, but now i get this:

  1. Try to add the line

    application/x-javascript    mjs;
    

    in the file /etc/nginx/mime.types;

  2. Inside Angular NX Module Federation, fixed it by changing nginx config file inside every microfrontends. That fixes MIME and CORS errors.

    MIME: types { ... }
    CORS: add_header Access-Control-Allow-Origin *; inside server{}

    This is nginx config file:

    events{}
    http {
        include mime.types;
        server {
            listen 80;
            server_name localhost;
            root /usr/share/nginx/html;
            index index.html;
        add_header Access-Control-Allow-Origin *;
        types 
            {
