Like others udger-updater-win and udger-updater-linux, this module handle udger sqlite database update. Differences with other updaters:
- 100% nodejs
- Dump differences between database versions (all tables)
- nodejs >= 8.9.0
- datafile v3 (udgerdb_v3.dat) from https://data.udger.com/
- a valid subscription key
npm install udger-updater-nodejs
const fs = require('fs-extra');
let options = {
subscriptionKey:process.env.UDGER_KEY||'YOUR_SUBSCRIPTION_KEY_HERE',
currentDatabase:'./udgerdb_v3.dat',
// you can force a temporary filename,
// if not set, it will use os tmpdir with a random filename
// nextDatabase:'./tmpFile.dat'
};
console.log("tmp file: %s", options.nextDatabase);
const udgerUpdater = require('../')(options);
udgerUpdater.on('error', (err) => {
console.log('an error occured');
console.log(err);
})
udgerUpdater.on('needUpdate', (needUpdate, versions) => {
if (needUpdate) {
console.log('udger database should be updated');
console.log(JSON.stringify(versions, null, 4));
return udgerUpdater.downloadNow();
}
console.log('udger database already up to date');
console.log(JSON.stringify(versions, null, 4));
});
udgerUpdater.on('downloading', (percent) => {
if (percent % 33 === 0 || !percent || percent === 100) {
console.log('downloading udger database ... %s', percent+'%');
}
});
udgerUpdater.on('downloaded', () => {
console.log('downloaded');
udgerUpdater.makeDiff({
itemsDisplayedMax:1000,
htmlReport:true
});
});
udgerUpdater.on('diffing', (sqliteTableName) => {
console.log('diffing %s', sqliteTableName);
});
udgerUpdater.on('diffDone', () => {
console.log('diff done');
// warning, at this point, every process using current database
// must close connection. New database can not be copied if used.
fs.copy(options.nextDatabase, options.currentDatabase, err => {
if (err) return console.error(err);
console.log('%s has been updated', options.currentDatabase);
})
});
udgerUpdater.checkForUpdate();
