            How to handle duplicate packages from NPM package?
            Asked 2022-Mar-10 at 15:14

            I have an NPM package I am working on which has a dependency of react. I then have a test app which has react installed as a dependency. When I import my npm package into the test app, I get the following error:

            Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:

            1. You might have mismatching versions of React and the renderer (such as React DOM)
            2. You might be breaking the Rules of Hooks
            3. You might have more than one copy of React in the same app

            Running npm ls react in my test app suggests I might have a duplicate of react:

            craco's Github readme, states that it is supporting Create React App (CRA) 4.*. By this statement, I'm assuming CRA 5 is not officially supported by craco.

            However, this repository utilizes both CRA 5 and craco (but I have not verified that it is working). Use this repository to compare your setup (after verifying that the linked repositry is working), and try different settings/configs to see if you get further.

            Divide different node_exporter memory types by the total memory using group_left
            Asked 2022-Jan-16 at 08:39

            I would like to create a graph of the proportion of total memory consumed by each of the following for a given instance:

            • node_memory_MemFree_bytes{instance="$instance"}
            • node_memory_MemAvailable_bytes{instance="$instance"}
            • node_memory_Buffers_bytes{instance="$instance"}
            • node_memory_Cached_bytes{instance="$instance"}

            I know I can create a single graph from 4 separate queries where each metric is divided by node_memory_MemTotal_bytes{instance="$instance"}:

            • Query A: node_memory_MemFree_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
            • Query B: node_memory_MemAvailable_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
            • Query C: node_memory_Buffers_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
            • Query D: node_memory_Cached_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}

            I feel like there should be a terser way of doing this with group_left since the right hand side is the same for each query and the left hand side can be reduced to a single query:

            • Left: {__name__=~"node_memory_(MemFree|MemAvailable|Buffers|Cached)_bytes",instance="$instance"}
            • Right: node_memory_MemTotal_bytes{instance="$instance"}

            If I understand the "Operators" docs and this blog post correctly, I should be able to use group_left to do this in a single query. However, I've been unable to do so.

            I reason that since the left and right side of the equation have exactly the same labels excluding __name__, I shouldn't need to use ignoring or on for the group_left operator:

            ANSWER

            Answered 2022-Jan-16 at 08:39

            PromQL strips metric names before matching time series on the left and right side of binary operator such as / - see these docs. In your case time series on the left side differ only by metric names, so PromQL sees series with identical sets of labels on the left side. The solution is to copy metric names for left-hand side time series into another label before applying the / operator and then ignoring this label during the / operation. This can be done with label_join or label_replace functions:

            Ajax Requests with node server in another folder
            Asked 2021-Dec-17 at 13:50

            So i'm new in JS and i have a task for mastering Ajax Requests.I should send an email input from form to the server and a lot more,but i can not figure out how to send this data to a server that is in another folder.I lost all my nerves with this task and i dont know what to do. So,i have a folder personal-website-server and another folder src where is my project,both folders are in another folder,the parent. It looks like this :
            ./
            dist < webpack bundle folder
            node_modules
            personal-website-server
            / package.json in personal-website-server
            src
            and package.json in the parent folder Image for more understanding:

            So,i should do this:
            Upon clicking on the "Subscribe" button, implement the functionality for sending a user email to the server. For that, make POST Ajax request using http://localhost:3000/subscribe endpoint. The call to the server should only be made when the form is valid (the validate function )
            The connection is made through a proxy to the server,idk how this thing works and i get it hard to do this task because its not so described.
