Source-map-explorer Unable To Map
Tijuana Strauhal
Performance matters, you probably already heard that before. Today, in FE applications we add tons of code to get our tasks done. In the meantime, we add modules, dependencies, functions, templates, directives, etc.
What is source-map-explorer?
The source map explorer determines which file each byte in your minified code came from. It shows you an interactive tree-map visualization to help you debug where all the code is coming from.
Before starting I would like to recommend this video from Stephen Fluin, angular team member. You will find some very interesting concepts about how to measure and improve performance. Additionally, the video recommends source-map-explorer.
Hi Jan, glad it helped. I just ran the report in a big project and I don't have any "No Source". Seems to be some source code not able to be classified.
I would try a couple of things
1- remove content under /dist and run ng build --prod again
2- run the report with webpack-bundle-analyzer and see if you got the same (just to compare, you can check this post dev.to/salimchemes/analyzing-angul...)
The source map explorer determines which file each byte in your minified code came from. It shows you a treemap visualization to help you debug where all the code is coming from. Check out this Chrome Developer video (3:25) for a demo of the tool in action.
--no-root: By default, source-map-explorer finds common prefixes between all source files and eliminates them, since they add complexity to the visualization with no real benefit. But if you want to disable this behavior, set the --no-root flag.
--no-border-checks: Disable invalid mapping column/line checks. By default, when a source map references column/line with bigger index than available in the source source-map-explorers throws an error indicating that specified source map might be wrong for the source.
The promise is rejected when there is a fatal error or all bundles explore failed. Reject reason is either explore result object (the same one returned when promise resolved) or Error object with code property specified.
When gzip option (or --gzip parameter) is specified result size calculated as gzip size. Due to the nature of compression a gzip file size is inaccurate. It means that removing a 1k gzipped file in a bundle may reduce the bundle size by less than 1k. Also it's impossible to calculate unmapped bytes because the sum of spans' gzip sizes isn't equal to gzip size of the source file.
In Google Chrome, you can collect code coverage stats. source-map-explorer accepts path to via --coverage argument (or coverage API option) and attempts to color code the heat map. This allows you to find the code that is not strictly needed for the initial page load and helps to identify the ideal ways to code split.
Red boxes correspond to code that would only be executed if the user took some action, or if some condition was met. For example, it may be a component inside of a dropdown the user never interacted with, or components that are only needed if the user opens a modal. In cases where the parent is green but the boxes inside are red, that means maybe some "initialization" logic ran, but the inner code never ran. Maybe we mounted a button, but not the other components in that module that are only needed if and when the user clicks the button, in that case, I would have the button trigger the rest of the code to load.
The heat map feature helps you identify the code that is needed for a fast initial page load (green), as well as helps to identify the code that can be (potentially) deferred because it doesn't run until the user interacts with some feature (red).
Recently, ArcGIS Pro has been unable to see local files, folders, etc. on my machine when attempting to save a project file, add data from local, or attempting to open an existing project file. I have ArcGIS Pro version 2.7.2 installed and my machine is running Windows 10 Enterprise Version 20H2. I have uninstalled and reinstalled, then let the program update itself to the most recent version. When installing, I have selected the option to allow the program to be available to all users. If I run the program as an administrator, the file explorer functions as expected but this is not a workable solution for me at this time.
Something else to try, is to go into your Options settings in Pro and select where you want your project files to automatically save and/or unpackage. Ive attached some screenshots of where to find these settings also. Im not sure if this will help with your existing issues, but it may help you work around them or it may help ArcGIS Pro direct itself to your desktop location.
I had same exact issue. I removed my folder connection(s) in ArcGIS Pro- Catalog Pane. Then I re-created the folder connection one level up, and now I can see the folder I was looking for. The first time, I created the folder connection, I set it to the subfolder that I wanted to access, but then it becomes tricky trying to access that folder using Save-As. So what worked for me was setting the folder connection to a main directory that has all of the subfolders that I will need access to, but not setting the folder connection directly to the subfolder itself. Hope that helps.
Web Performance is becoming more and more demanding as Web applications
continue to grow in size and complexity. One of the biggest culprits of Web Performance issues is JavaScript. JavaScript can be slow to download but also slow to execute depending on the network and device capabilities.
To keep Angular performance fast we can use lazy loading and dynamic imports to load code as needed on demand. This can greatly reduce the amount of JavaScript required to load and run on the client. However, even when following best practices, sometimes a single third party dependency can break all performance progress.
This command will build our Angular application with all the optimization the Angular CLI uses and produce source map files of the output code. The source maps allow the compiled final output to be mapped to its original code before compilation.
Here we can see the output of the ng-pokedex project. We can see all the JavaScript and dependencies within each JavaScript bundle. This visualization makes it easy to identify what code is being loaded.
While the Angular CLI uses Webpack for some of its bundling, it also makes additional optimizations on top of Webpack. Because of these optimizations, it's important to use the source-map-explorer to test the final output and not the webpack-bundle-analyzer that is commonly used with Webpack based applications.
Hey there, I was looking for the same thing because I was unable to find the OneDrive for my business account too. I believe the solution you are looking for is in the following link:
Sync files with OneDrive in Windows (microsoft.com)
If you get a error telling you that OneDrive is already installed. Even better. Because that means you only need to add the Microsoft365 or Office365 account.
To add the account to the existing OneDrive installation hover your mouse over the taskbar.
Step 1. Click the OneDrive icon next to the clock.
Step 2. Click "Help & Settings" and click "Settings" from the drop-down menu
Step 3. Microsoft One Drive properties pop up will appear. Click Add account.
The OneDrive icon for the second account will appear on the taskbar next to the personal OneDrive icon.
I hope this helps you and resolves your issue @Pepijn van Beusekom
Had the same issue. Hit Start, type OneDrive, open "OneDrive App" - looks the same as a file explorer, except in the address bar you now see "Syncing". Left click "Syncing" and you'll see a pop up with a gear icon bottom right. Select that for Settings, go to the second menu item on the left column, "Account" and hit "+ Add an account" (top right of screen.)
So this all points to a problem related to Acrobat not recognizing the computer's drive mapping --- but this problem does not exist on any other workstation on the network (all Win8 virtual machines using Acrobat Pro X). But I cannot figure out what the problem is.
Unfortunately, I have had no progress solving it. I thought I might have come up with a solution when I tried remapping drives. I also have had random times when it has worked for no apparent reason --- but nope, the problem comes back very quickly. Uninstalling and reinstalling does not work. The problem exists only in Acrobat; all other programs recognize the drive mapping.
I am having the same problem too. I tried disabling Enhanced Security but that did not help (even after exiting the program and restarting). If I copy those files on my local drive (from my NAS drive), everything is fine. So, I would conclude the problem is accessing files on a network drive. I tried opening via File > Open, also, from File Explorer, but no luck. Says error reading document.
I'm having this issue as well. Any files I try to open over our network now won't open: "There was an error opening this document. This file cannot be found.", same file opens fine locally. I tried re-starting my system but no change.
Bit of history: Acrobat was running fine for me but a recent Acrobat/company update coming in at the same time messed up the Acrobat update and it wasn't able to complete. We tried to install the update multiple times but Acrobat wouldn't launch at all. We re-installed Acrobat last week and it seemed fine, but I'm also not sure if I tried to open any files from over the network.
I have this issue as well. Unfortunately, I ALSO have Error 16 at the same time, which can seemingly ONLY be fixed by running as administrator. Running as administrator allows me to access files on my hard drive without issue, but I am completely unable to access network locations or open network files through Acrobat.
Disabling "run as administrator" allows me to open files both on my computer and on the network, however, a few seconds later, Error 16 pops up and closes Acrobat. I've tried all other Error 16 fixes, including modifying permissions on SLStore and Adobe PCD, Cleaner and reinstall, and a few others.
