@stevenjoezhang We could add a check for whether the theme is available after the generation.

The rate limit of GitHub api is 5000 requests per hour

const yaml = require('js-yaml');
const fs = require('fs');
const https = require('https');

function load(type) {
    const file = fs.readFileSync(`./source/_data/${type}.yml`);
    return yaml.load(file);
}

function request(url) {
    if (!url.startsWith('https://github.com/')) {
        console.log(url);
        return;
    }
    url = url.replace(/(\/$|\.git$)/g, '');
    https.get('https://api.github.com/repos/' + url.replace('https://github.com/', ''), {
        headers: {

    }).on('error', err => {
        console.error('Failded to download release messages.');
        console.log(err);

function validatePlugins() {

    let url = plugins.map(item => item.link);

@stevenjoezhang

Use hexo's built-in API to get site.data so that we could implement it as a filter:

const themesMap = hexo.locals.get('data').themes;
const pluginsMap = hexo.locals.get('data').plugins;

Also, we can simply request the given link & preview to see if it whether returns 200 or not.

That's right, and it's possible to display a warning on the hexo.io website, such as "the repository is currently not accessible", or "the plugin has not been updated for years".
