Puppeteer Chromium Resolver

Tool to resolve puppeteer and chromium faster, detect local installed chromium, download chromium with custom mirror host, cache chromium revision out of node_modules, test chromium headless being launchable.

• Tool to customize puppeteer
• Detect local chromium automatically
• Download chromium from custom mirror host
• Cache chromium to custom local folder
• Try launching chromium and resolve launchable and version
• Resolve chromium executablePath and puppeteer

Install

npm i puppeteer-chromium-resolver

Usage

[Async] dynamic detection and downloading chromium

const PCR = require("puppeteer-chromium-resolver");
const options = {};
const stats = await PCR(options);
const browser = await stats.puppeteer.launch({
    headless: false,
    args: ["--no-sandbox"],
    executablePath: stats.executablePath
}).catch(function(error) {
    console.log(error);
});
const page = await browser.newPage();
await page.goto("https://www.npmjs.com/package/puppeteer-chromium-resolver");
await browser.close();

[Sync] chromium will be pre-downloaded when PCR installation, so calling getStats() will get PCR stats from previous installation.

const PCR = require("puppeteer-chromium-resolver");
const options = {};
const stats = PCR.getStats(options);
if (stats) {
    stats.puppeteer.launch({
        headless: false,
        args: ["--no-sandbox"],
        executablePath: stats.executablePath
    }).then(function(browser){
        //...
    }).catch(function(error) {
        console.log(error);
    });
}

Default Options

const options = {
    // the chromium revision to use
    // default is puppeteer.PUPPETEER_REVISIONS.chromium
    revision: '',

    // additional path to detect local chromium copy (separate with a comma if multiple paths)
    detectionPath: '',

    // custom path to download chromium to local, require dir permission: 0o777
    // default is user home dir
    downloadPath: '',

    // the folder name for chromium snapshots (maybe there are multiple versions)
    folderName: '.chromium-browser-snapshots',

    // the stats file name, cache stats info for latest installation
    statsName: '.pcr-stats.json',

    // default hosts are ['https://storage.googleapis.com']
    hosts: [],

    cacheRevisions: 2,
    retry: 3,
    silent: false
};

see lib/options.js

Option from root package.json with "pcr" object

{
    // ...
    "pcr": {
        "revision": "1138907"
    }
}

Return Stats

Property	Type
revision	String	current chromium revision
executablePath	String	chromium executable path
chromiumVersion	String	chromium version
launchable	Boolean	chromium launchable
puppeteerVersion	String	puppeteer version
puppeteer	Object	puppeteer module

Test Cases

How to make puppeteer work with puppeteer-chromium-resolver

• 1, Sets env PUPPETEER_SKIP_DOWNLOAD to skip download Chromium when installation (.npmrc)

PUPPETEER_SKIP_DOWNLOAD=true

• 2, Sets env PUPPETEER_EXECUTABLE_PATH to PCR executablePath globally or pass in launch option executablePath

(async () => {

    const PCR = require("puppeteer-chromium-resolver");
    const puppeteer = require("puppeteer");
    const stats = await PCR({});
    //update global env
    process.env.PUPPETEER_EXECUTABLE_PATH = stats.executablePath;

    //or specify executablePath
    const browser = await puppeteer.launch({
        executablePath: stats.executablePath,
        headless: false
    });

})();
