Create Docker environment

web2js has some dependencies to produce core.dump. It is hard to setup the local environment, therefore I want the Docker environment.

FROM adnrv/texlive:full 

# Update tex packages
RUN tlmgr update --self --all

ARG WORKDIR=/usr/var
WORKDIR ${WORKDIR}

# Install apt pacakges
RUN apt update && apt install -y \

# Install npm and node

  && apt install ./nodejs_${NODE_MINOR_VERSION}-deb-1nodesource1_amd64.deb \
  && rm nodejs_${NODE_MINOR_VERSION}-deb-1nodesource1_amd64.deb

# Install binaryen
ARG BINARYEN_VERSION=91
RUN wget https://github.com/WebAssembly/binaryen/archive/refs/tags/version_${BINARYEN_VERSION}.tar.gz \
  && tar -zxf version_${BINARYEN_VERSION}.tar.gz \
  && cd binaryen-version_${BINARYEN_VERSION} \
  && cmake . && make \
  && make install \
  && cd ../ && rm -rf binaryen-version_${BINARYEN_VERSION} version_${BINARYEN_VERSION}.tar.gz

# Install node packages
COPY package.json ${WORKDIR}/
RUN npm install

# Build
COPY . ${WORKDIR}/

# Produce tex.wasm and core.dump
RUN make core.dump

# Compile sampleLatex.tex by running
# RUN node tex.js sample/sampleLatex

This is my Dockerfile but ! I can't read TEX.POOL. error has occurred at node initex.js.

The following is that log.

! I can't read TEX.POOL.
[Object: null prototype] {
  '0': Memory [WebAssembly.Memory] {},
  getStackPointer: [Function: 20],
  setStackPointer: [Function: 21],

}
! I can't read TEX.POOL.

This message is sent out from the source file but I don't know what is needed or wrong. tex.pool file is certainly exist by tangle. How can I fix it?

@nosuke23,

I noticed your post on the TeX Stack Exchange and subsequent issues here on GitHub. I'm working on a similar endeavour with the Tikz Plugin for Obsidian using web2js and tikzjax. Have you made any progress on the Dockerfile issue above?

Here's the challenge I'm facing: After compiling core.dump and tex.wasm without the {pgfsys-ximera.def} driver, I ran into an issue where no input.dvi file was produced in the browser when using the tikjax build:

Error: Could not find file input.dvi
    at Module.readFileSync (run-tex.js:20437:8)
    at texify (run-tex.js:20936:51)

When running node initex.js (with the driver), I encountered this error:

Below is my Dockerfile attempt, aiming to encapsulate the necessary steps:

FROM debian:buster

# Clean up
RUN apt-get -y autoclean && rm -rf /var/lib/apt/lists/*

# Set python2.7 as default python for node packages
RUN rm -f /usr/bin/python && ln -s /usr/bin/python2.7 /usr/bin/python

# Compress the wasm and dump files
RUN gzip tex.wasm
RUN gzip core.dump

# Copy to the tikzjax directory
RUN mv tex.wasm.gz /app/tikzjax
RUN mv core.dump.gz /app/tikzjax

# Build dvi2html separately as it fails when built with tikzjax
WORKDIR /app/dvi2html
RUN npm install
RUN npm run build

# Build tikzjax

# Remove dvi2html from package.json
RUN sed -i '20d' package.json 
RUN npm install

# Copy dvi2html to node_modules
RUN cp -r /app/dvi2html node_modules

# RUN npm run devbuild
RUN npm run build
RUN npm run postbuild

CMD [ "/bin/bash" ]

Any insights or feedback would be immensely appreciated.
