npm init -y
npm install -D markdown-it-pdf
Of course, you can install it globally or use it as a command only without installing it (using

command).
[step1]: First of all you write documents in Markdown
First, create the source code documents in Markdown with the following directory structure:
<project-root>
+ src
+ img
| + logo.png
| + img001.jpg
+ sub01
| + sub01-001.md
| + sub01-002.md
+ styles
| + style001.css
| + style002.css
+ sample001.md
+ sample002.md
+ package.json
+ node_modules
- You can convert multiple Markdown files to PDF files in bulk.
- The target files are searched recursively.
- You can also specify the style (
css
) to be applied to Markdown. - You can also specify the image data (
png
orjpg
) to be used in Markdown.
[step2]: Determine the rendering method.
You can select the rendering method as follows:
|Method| Summary |
|---|---|
| CLI Printer | You can generate PDF files in bulk by using the CLI. |
| CLI Server | You can start an HTTP server on localhost
to distribute HTML files generated from Markdown. |
| Node.js API | You can extend this library by using markdown-it-plugin
s, or embed it in your own application and convert Markdown to PDF. |
[step3][CLI] Configure
Create configuration file (named markdown-it-pdf-config.json
) on root directory like bellow:
{
"recursive": true,
"externalUrls": ["https://hoo.bar/styles/test.css"],
"margin": {
"top": "12.7mm",
"bottom": "12.7mm",
"left": "12.7mm",
"right": "12.7mm"
}
}
See more information on this article - About Configurations.
[step4][CLI] Execute
This tool include Command Line Interface which launches the server and prints the output them pages to the files as PDF.
Printer: Convert multiple Markdown files to PDFs
markdown-it-pdf print src pdf --config markdown-it-pdf-config.json
If you want to print(convert) markdown files into PDF files, then you use print
command.
First option is the root directory of the markdown files.
Second option is the output directory of the PDF files.
Server: Start the HTTP server to distribute HTML
markdown-it-pdf serve src --config markdown-it-pdf-config.json
If you want to start the HTTP server to distribute HTML, then you use serve
command.
For example if you want to print yourself, want to share your MD files with others, or want to debug before writing CSS
files, then you use serve
command.
The first option is the root directory of the markdown files.
Other options for the CLI
|Option| Alias | Summary |
