Hi Dr.Mackay, first of all thanks for your library and the hard work you've done ^_^ .

 

I've been thinking about making a project which would need to auto-download game from the user library, by this i mean, i could sign in through steam, and use your library to get all game info, would be possible to automate the process of downloading the game into imagine, a remote server without having to interact to a UI Steam client directly? Another think would be interesting is to interact with updates in games, by knowing what games require updates before an instance could be launched in the machine that previously has downloaded the game. All of this in case the first one is even possible, don't know if a future feature in your lib could fit or if i'm speaking about other completely thing, hope not  :D.

 

Sorry for my English, i'm not native and again thanks for your time!

Nope. This library simply executes web requests (or protobufs) and handles cookies etc. It could technically do it but I doubt that itll be added since it's not something steam's server does, the library would have to do a lot more too

I've been trying to create an app that can do this, but I've been running against weird errors. I'll share the code with the hope that dr. mckay or someone else can assist me into getting this to work.

const fs = require("fs");
const path = require("path");
const mkdirp = require("mkdirp");
const SteamUser = require("steam-user");

const client = new SteamUser();

// ...
// login
// ...

client.on("contentServersReady", function() {
    downloadGame(207140);
    //doManifest(480, 481, "840604261173631294", path.join(__dirname, "480"));
});

function downloadGame(appid) {
    client.getProductInfo([+appid], [], true, apps => {
        for (let appid in apps) {
            const app = apps[appid].appinfo;
            const depots = Object.keys(app.depots).filter(id => !isNaN(parseInt(id)));
            depots.forEach(depotid => {
                const depot = app.depots[depotid];
                if (depot.manifests) {
                    doManifest(appid, depotid, depot.manifests.public, path.join(__dirname, appid));
                } else if (depot.depotfromapp) {
                    client.getProductInfo([+depot.depotfromapp], [], true, apps => {
                        const a = apps[depot.depotfromapp].appinfo;
                        const d = Object.keys(a.depots).filter(id => !isNaN(parseInt(id)));
                        if (d.manifests) {
                            doManifest(depot.depotfromapp, depotid, d.manifests.public, path.join(__dirname, appid));
                        }
                    });
                }
            });
        }
    });
}

function doManifest(appid, depotid, manifestid, savefolder) { // 480, 481, "840604261173631294", "480"
    client.getManifest(+appid, +depotid, manifestid.toString(), (error, manifest) => {
        if (error) {
            console.log(error);
            return;
        }

        //console.log(JSON.stringify(manifest, null, 4));
        const files = manifest.files;

        if (files) dlFile();

        function dlFile() {
            if (files.length > 0) {
                const file = files.shift();
                const filepath = path.join(savefolder, file.filename);
                console.log(filepath);
                mkdirp(path.dirname(filepath), error => {
                    if (error) {
                        console.log(error);
                    }

                    client.downloadFile(+appid, +depotid, file, filepath.toString(), error => {
                        if (error) {
                            console.log(error);
                        }
                        dlFile();
                    });
                });
            }
        }
    });
}

Running downloadGame(207140) gives this result:

Thank you, that resolves that problem. Do you have any idea what to do to fix these problems? Only top error was a fatal one that made the program crash, others are from console.log(error).

That top one looks kind of like you got a corrupt chunk.

 

All your connect timeouts are likely due to CDN servers being down/slow to respond. Just retry.

 

File checksum mismatch is weird, that means the decompressed/decrypted data in the chunk didn't match the sha1 we expected.

 

And all the "Fail" errors is just Steam being Steam.
