How to use auto migration with loopback 4 for mysql datasource

Question

请帮忙，关于使用MySQL数据源在loopback4中进行自动迁移没有任何帮助

Answer 1

let auth = server.dataSources.auth;
auth.isActual( function(err, actual) {
    if (!actual) {
      auth.autoupdate(function(err, result) {
        console.log('Error in autoMigrate script',err);
        console.log("All tables are updated..");
      });
    }
  });

I hope this clarifies your query;
And auth is a datasource defined in datasource.json
