How publication works?

Publication is the process that starts when the client presses button "Publish" in website builder toolbar. The process can be divided into several parts that are executed one after another in a specified order:

• saving draft — this step saves website draft — the same action that is triggered when pressing button "Save Draft". This step takes <1 second; when it is completed the state "preparing..." is displayed;
• website generation — during this step website builder generates final website files that will be published to client's hosting. They consist mostly of .php, .js, .css and different media files. During this step the state "building website..." is displayed;
• connection to hosting FTP server — this is the 1st step of deploying part. Website builder tries to establish FTP connection with hosting server where it will publish website. The connection is made with 3 different IPs in specified order until it finally connects (when it connects with some of them, it does not try the rest):
  • IP address which was passed by hosting control panel API to website builder plugin when website builder was opened (in case "Custom (API)" is used, it is defined by parameter "apiUrl");
  • IP address of domain that was opened (in case "Custom (API)" is used, it is defined by parameter "baseDomain" [or "domain" if "baseDomain" is not provided]);
  • remote IP address of server that made API call to website builder during opening;
  During this step the state "connecting..." is displayed;
• logging to hosting FTP account — this is the 2nd step of deploying part. After successful connection to FTP server, website builder tries to log in with username and password of FTP account. Builder gets FTP data from website builder plugin on hosting control panel (API) (in case "Custom (API)" is used, FTP details are defined by parameters "username" and "password");
• files uploading — this is the 3rd step of deploying part. During this step website files are uploaded to hosting. Note that only changed files are uploaded from last publication. This is usually the longest part. It can take from few seconds to few minutes (depending on website size and connection speed between website builder and hosting servers);
• verification — this is the 4th step of deploying part. After successfully uploading website files (only changed) to hosting, website builder makes verification the purpose of which is to check if all required website files are on hosting and are all correct. During this step website builder connects to website hosting on port 80 or 443. The connection is made also with different IPs in the same order and same IPs as during website builder connection to FTP server with one difference — firstly it tries IP address which could successful establish connection to FTP server. During this step the state "verifying..." is displayed;
• files re-uploading (full) (optional) — this step is taken only in the case verification returned negative, that is some website file on hosting was removed or changed since last publication. During files re-uploading, connection to FTP is made again as described in step (3). When uploading ends, no second verification is made.
