Playwright HTML to PDF
A modern html to pdf scheme based on playwright, Support more html and css technologies
Installation
- Install pwhtmltopdf
pip install pwhtmltopdf
- Install chromium
playwright install chromium
Usage
Simple example:
import asyncio
import pathlib
from pwhtmltopdf import HtmlToPdf
async def this_from_url():
async with HtmlToPdf() as htp:
await htp.from_url("https://playwright.dev/", "from_url.pdf")
async def this_from_file():
async with HtmlToPdf() as htp:
# Make sure the current directory has a test.html file
await htp.from_file("test.html", "from_file.pdf")
async def this_from_string():
async with HtmlToPdf() as htp:
content = pathlib.Path("test.html").read_text()
await htp.from_string(content, "from_string.pdf")
if __name__ == '__main__':
asyncio.run(this_from_url())Render fill:
When local_render is equal to true, jinja2 template syntax will be used to render filled html,
If html needs to use local static resources, you need to set static_root,
If you want to render filled data dynamically to generate pdf(Based on jinja2), try the following method
import asyncio
import pathlib
from pwhtmltopdf import HtmlToPdf
async def this_render_from_url():
file_path = pathlib.Path("tests/images.html").absolute()
async with HtmlToPdf(static_root="tests/static",
wait_until="load", print_background=True) as htp:
await htp.from_url(
f"file://{file_path}",
"tests/effect/from_url/local_url_render.pdf",
local_render=True,
char_code=123,
)
async def this_render_from_file():
htp = HtmlToPdf(static_root="tests/static")
await htp.from_file(
"tests/images.html", "tests/effect/from_file/images_render.pdf",
local_render=True, char_code=123
)
await htp.close()
async def this_render_from_string():
content = pathlib.Path("tests/images.html").read_text()
htp = HtmlToPdf(static_root="tests/static")
await htp.from_string(content, "tests/effect/from_string/images_render.pdf",
local_render=True, char_code=123)
await htp.close()
if __name__ == '__main__':
asyncio.run(this_render_from_url())
