The deploy is the moment when something can go wrong, so Hostman helps you avoid downtime during deploy by employing these measures:
We do a clean deploy each time. This helps to avoid issues with the cache or junk files previously created by the code. We install all dependencies and build the code each time. It takes longer, but it's more stable.
We use a monitoring link to deploy without downtime. This means that even if everything was built correctly, we will check that your application is working properly before we redirect traffic to it and stop the previous instance.
