Build And Share Your Single-page App With React, Node and Pouchdb, part IV

Now it’s time to talk about the fun part: the publishing! You built your bookmark manager. You enjoy using it. What would be better is that others use your app. You could publish it on the web and add user management and authentication. But you will be responsible of the data of others. You would have to ensure too that your server is always up and running. But it’s boring and time consuming. Another option is to publish your app on a registry. From there other people would be able to install it on their hardware (like on smartphone or desktop). Everyone would be in charge of his own deployement and his data.

Timeline Retrospective: The Conflict Crusher Method

Do you remember the last sprint or project where you faced terrible issues? E.g; Production servers crashed after delivery, few features were shipped or requirements were not clearly understood. This kind of situations are common and lead to a lot of frustration. Most of the time, you could be surprised by how fast things went wrong and felt disappointed in front of that big mess. Then, you try your best to fix the delivery. That’s all good but, once you put the situation back to normal, another problem arises: how do you disable conflicts that were raised by that chaos?
