mermaid.cli

Command-line interface for mermaid.

This CLI tool takes a mermaid definition file as input and generates svg/png/pdf file as output.

Install locally

Some people are having issue installing this tool globally. Installing it locally is an alternative solution:

yarn add mermaid.cli
./node_modules/.bin/mmdc -h

Or use NPM:

npm install mermaid.cli
./node_modules/.bin/mmdc -h

Install globally

❗️ We do NOT recommend installing it globally because both YARN and NPM could fail to install a command line tool globally properly due to weird permission issues.

yarn global add mermaid.cli

Or

npm install -g mermaid.cli

Examples

mmdc -i input.mmd -o output.svg

Linux sandbox issue

node:8281) UnhandledPromiseRejectionWarning: Error: Failed to launch chrome!
[0416/092218.828861:ERROR:zygote_host_impl_linux.cc(88)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.
(node:8191) UnhandledPromiseRejectionWarning: Error: Failed to launch chrome!
[0416/091938.210735:FATAL:zygote_host_impl_linux.cc(124)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/master/docs/linux_suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.

First and foremost, you should not run as root and you should upgrade your Linux kernel to latest version.

But if you don't want to follow the advice above and just want to disable sandbox, here you go:

Create a puppeteer-config.json file:

{
  "args": ["--no-sandbox"]
}

And when you invoke mmdc:

mmdc -p puppeteer-config.json ...
