Add Nodejs to the Dockerfile.

[markanton1727]

Thank you very much for the repository; it has been very helpful to me. However, I have a problem. When trying to install the Bootstrap gem, I receive the following error: usr/local/bundle/gems/execjs-2.9.1/lib/execjs/runtimes.rb:68:in autodetect': Could not find a JavaScript runtime. See https://github.com/rails/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable).

I have attempted to install Node.js within the Dockerfile, but I have not succeeded. Is it possible to add the installation of Node.js for the proper functioning of the Bootstrap gem?

Regards.

Good question. One of the experiments with this repository was to see if node.js could be avoided altogether. So, it is not installed on purpose (at this point).

What version of the Bootstrap gem are you using? I'm curious to check it out.

The new Dockerfile in Rails 7.1 does have a way to include node still though: https://github.com/rails/rails/blob/main/railties/lib/rails/generators/rails/app/templates/Dockerfile.tt#L24

You can try adding that block directly to your Dockerfile

# Install JavaScript dependencies
ARG NODE_VERSION=<%= node_version %>
ARG YARN_VERSION=<%= dockerfile_yarn_version %>
ENV PATH=/usr/local/node/bin:$PATH
RUN curl -sL https://github.com/nodenv/node-build/archive/master.tar.gz | tar xz -C /tmp/ && \
    /tmp/node-build-master/bin/node-build "${NODE_VERSION}" /usr/local/node && \
    npm install -g yarn@$YARN_VERSION && \
    rm -rf /tmp/node-build-master
