Pobot
Promise-oriented Chrome automator.
Usage
Pobot is still in very heavy alpha. Its API has a lot of pipes and wires sticking out.
Scripting
In the example below, we navigate to a page and then inject some javascript. PLEASE NOTE In the code, it looks like a normal callback is passed to pobot.inject(). This is simply for the convenience of syntax highlighting in the editor ONLY. The callback passed here will be converted to a string behing the scenes and run in another JS environment ENTIRELY (the webpage). Of course, normal namespacing rules will NOT apply.
Pobot.get([]).then(pobot=>{
pobot.goto('https:google.com').then(() => {
return pobot.inject(() => {
document.querySelector('input[type=text]').value = 'Sean Morris';
document.querySelector('input[type=submit]').click();
}).then(()=>{
return pobot.loaded();
});
}).then(() => {
return pobot.inject(() => {
return document.querySelector('#search a').innerText.trim();
}).then( linkText => {
accept(linkText);
});
});
});CLI
Pobot can be installed globally via:
$ npm install -g pobotand can be used with scripts like so:
$ pobot ./relative-path-to/script.jsScripts are formatted like modules and may export functions or promises:
const readline = require('readline');
const populateSearch = (keyword) => {
const field = document.querySelector('#search input[type="search"]');
if(!field)
{
return;
}
field.value = keyword;
};
const peformSearch = () => {
const button = document.querySelector('#search button[type="submit"]');
button.click();
};
const clickFirstLink = () => {
document.querySelector('.center-ns a').click();
};
module.exports = (pobot, args) => new Promise((accept,reject)=>{
console.log('Opening npmjs.com...');
pobot.goto('http://npmjs.com').then(()=>{
return new Promise((accept,reject)=>{
const rli = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rli.question('keyword:', (answer) => {
rli.close();
accept(answer)
});
});
}).then((keyword)=>{
console.log('Populating keyword...');
return pobot.inject(
populateSearch
, [keyword || args.shift() || 'pobot']
);
}).then(()=>{
console.log('Performing search...');
return pobot.inject(peformSearch);
}).then(()=>{
console.log('Clicking first link...');
setTimeout(() => { pobot.inject(clickFirstLink) }, 500);
}).then(()=>{
setTimeout(() => { accept('Done!.'); }, 5000);
});
});Pobot
