puppeteer-chromium-resolver

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
    // or you can use PUPPETEER_REVISION environment variable
    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']
    // or you can use PUPPETEER_DEFAULT_HOST environment variable
    hosts: [],

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

see lib/options.js

Option from root package.json with "pcr" object

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

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
    });

})();
