pioneerjs - a puppeteer framework
Pioneerjs is a puppeteer framework that uses the principle of Dependency Injection to inject all the resources(page,browser,...) you need.
- Pioneerjs helps you to manage the
BrowserandPageobjects of Puppeteer - It instantiates and automatically injects Page, Browser, ScriptContext objects for each runnable script
- You can use RunnableScript to run the puppeteer code and start it with @Runnable('https://xxx.com') decorator
- You can use InjectableScripts in any RunnableScript and inject them automatically using the @Inject decorator, no instantiation is needed, the Page, Browser, ScriptContext objects of an InjectableScript are the same as in the RunnableScript it is in, and InjectableScripts generally play the role of tool scripts
Getting Started
# init your package.json
npm init# install dependencies
npm install puppeteer-core @pioneerjs/core @pioneerjs/common
# or you can just install pioneerjs
npm install puppeteer-core pioneerjs# init typescript config
tsc --inittscondig.json
