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 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

(async () => {
    const PCR = require("puppeteer-chromium-resolver");
    const option = {
        revision: "",
        detectionPath: "",
        folderName: ".chromium-browser-snapshots",
        defaultHosts: ["https://storage.googleapis.com", "https://npm.taobao.org/mirrors"],
        hosts: [],
        cacheRevisions: 2,
        retry: 3,
        silent: false
    };
    const stats = await PCR(option);
    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 stats = PCR.getStats();
if (stats) {
    stats.puppeteer.launch({
        headless: false,
        args: ["--no-sandbox"],
        executablePath: stats.executablePath
    }).then(function(browser){
        //...
    }).catch(function(error) {
        console.log(error);
    });
}

Option from root package.json with "pcr" object

{
    "name": "",
    "version": "",
    "dependencies": {},

    "pcr": {
        "revision": "869685"
    }

}

Return Stats

Property	Type
revision	String	current chromium revision
executablePath	String	chromium executable path
folderPath	String	chromium folder path
local	Boolean	exists local chromium
url	String	chromium download url
launchable	Boolean	chromium launchable
chromiumVersion	String	chromium version
puppeteerVersion	String	puppeteer version
puppeteer	Object	puppeteer module

How to make puppeteer work with puppeteer-chromium-resolver

• 1, Stop the automatic download of Chromium with following settings in .npmrc

puppeteer_skip_download = true
PUPPETEER_SKIP_CHROMIUM_DOWNLOAD = true

(one more setting for puppeteer v2.x)

• 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
    });

})();
