snap-html

a robust, modern and high performance Python library for generating image from a html string/html file/url build on top of playwright

Highlight

• All Basics, Async ready, Sync support, Fully Typed
• Builtin batch generator for higher performance
• Build on top of the giant playwright, simplified of headless browser and driver installation
• Accept html/css string, and You can use with jinja2 for html templating

TODO

• Maybe you would like to add gitmoji to commit names. This is really funny. 😄

For building and deployment:

• GitHub integration.
• Makefile for building routines. Everything is already set up for security checks, codestyle checks, code formatting, testing, linting, docker builds, etc. More details at Makefile summary).
• Dockerfile for your package.
• Github Actions with predefined build workflow as the default CI/CD.
• Always up-to-date dependencies with @dependabot (You will only enable it).
• Automatic drafts of new releases with Release Drafter. It creates a list of changes based on labels in merged Pull Requests. You can see labels (aka categories) in release-drafter.yml. Works perfectly with Semantic Versions specification.

For creating your open source community:

• Ready-to-use Pull Requests templates and several Issue templates.
• Files such as: LICENSE, CONTRIBUTING.md, CODE_OF_CONDUCT.md, and SECURITY.md are generated automatically.
• Stale bot that closes abandoned issues after a period of inactivity. (You will only need to setup free plan). Configuration is here.
• Semantic Versions specification with Release Drafter.

Installation

pip install -U snap-html

python -m playwright install

or install with Poetry

poetry add snap-html

Then you can run

snap-html --help

snap-html --name Roman

or if installed with Poetry:

poetry run snap-html --help

poetry run snap-html --name Roman

Makefile usage

Makefile contains many functions for fast assembling and convenient work.

1. Download Poetry

make download-poetry

2. Install all dependencies and pre-commit hooks

make install

If you do not want to install pre-commit hooks, run the command with the NO_PRE_COMMIT flag:

make install NO_PRE_COMMIT=1

3. Check the security of your code

make check-safety

This command launches a Poetry and Pip integrity check as well as identifies security issues with Safety and Bandit. By default, the build will not crash if any of the items fail. But you can set STRICT=1 for the entire build, or you can configure strictness for each item separately.

make check-safety STRICT=1

or only for safety:

make check-safety SAFETY_STRICT=1

multiple

make check-safety PIP_STRICT=1 SAFETY_STRICT=1

List of flags for check-safety (can be set to 1 or 0): STRICT, POETRY_STRICT, PIP_STRICT, SAFETY_STRICT, BANDIT_STRICT.

4. Check the codestyle

The command is similar to check-safety but to check the code style, obviously. It uses Black, Darglint, Isort, and Mypy inside.

make check-style

It may also contain the STRICT flag.

make check-style STRICT=1

List of flags for check-style (can be set to 1 or 0): STRICT, BLACK_STRICT, DARGLINT_STRICT, ISORT_STRICT, MYPY_STRICT.

5. Run all the codestyle formaters

Codestyle uses pre-commit hooks, so ensure you've run make install before.

make codestyle

6. Run tests

make test

7. Run all the linters

make lint

the same as:

make test && make check-safety && make check-style

List of flags for lint (can be set to 1 or 0): STRICT, POETRY_STRICT, PIP_STRICT, SAFETY_STRICT, BANDIT_STRICT, BLACK_STRICT, DARGLINT_STRICT, ISORT_STRICT, MYPY_STRICT.

8. Build docker

make docker

which is equivalent to:

make docker VERSION=latest

More information here.

9. Cleanup docker

make clean_docker

or to remove all build

make clean

More information here.

📈 Releases

You can see the list of available releases on the GitHub Releases page.

We follow Semantic Versions specification.

We use Release Drafter. As pull requests are merged, a draft release is kept up-to-date listing the changes, ready to publish when you’re ready. With the categories option, you can categorize pull requests in release notes using labels.

For Pull Request this labels are configured, by default:

Label	Title in Releases
enhancement, feature	🚀 Features
bug, refactoring, bugfix, fix	🔧 Fixes & Refactoring
build, ci, testing	📦 Build System & CI/CD
breaking	💥 Breaking Changes
documentation	📝 Documentation
dependencies	⬆️ Dependencies updates

You can update it in release-drafter.yml.

GitHub creates the bug, enhancement, and documentation labels for you. Dependabot creates the dependencies label. Create the remaining labels on the Issues tab of your GitHub repository, when you need them.
