Actual behavior

I run the my script on a directory with 41214 SVG files and got the following error

function buildFont(config) {
  return webfont({
    files: config.inputFiles,
    fontName: config.fontName
  })
    .then(content => content)
    .catch(err => {
      console.log(err);
    });
}

Steps to reproduce the behavior

Get font generator repo:

git clone git@github.com:parlr/Hanzi-Pinyin-Font.git && cd Hanzi-Pinyin-Font
git check out  9b7bd1c

Get data extractor repo:

git clone git@github.com:parlr/chinese-data.git && cd chinese-data

Extract chinese data:

echo $'glyph\truby' > src/codepoint-ruby.tsv
awk '/U+/ && /kMandarin/{print $1"\t"$3}' src/Unihan_Readings.txt >> src/codepoint-ruby.tsv
./node_modules/.bin/csv2json --tsv ./src/codepoint-ruby.{tsv,json}

Generate font

cp ./src/codepoint-ruby.json ../src/data.json
cd ../  # back to Hanzi-Pinyin-Font
npm start

Question

How can I solve this?

Clearly a memory leak of some kind; While the last stack frame is indeed in this project, it's not necessarily the culprit. Have you analyzed the heap? If this isn't a task that needs to be run regularly, upping the memory limit might also be a solution.

[edouard-lopez]

Should not be a common task, but I

• upgraded to NPM@4
• raise the limit to --max_old_space_size=8192

and it still crashes.

[NaridaL]

Considering the linked issues have all been closed, I'm going to close this too.

[edouard-lopez]

For clarity, I solved my issue with following command (see commit):

node \
    --max_old_space_size=8192 \
    --optimize_for_size \
    --max_executable_size=4096 \
    --stack_size=4096 \
    --require babel-core/register \
./index.js
