Thread: [pgAdmin][RM4701] Webpack optimization

Hi Hackers,

Attached is the patch to optimise webpack bundled files for improving performance. 

@Ashesh Vashi Thank you for your suggestions and inputs.

Changes include:

1) Remove underscore-string and sprintf-js packages as we were using only %s. Instead, added a function to do the same. Also changed gettext to behave like sprintf directly.

2) backgrid.sizeable.columns was not used anywhere, removed. @babel/polyfill is deprecated, replaced it with core-js.

3) Moved few css to make sure they get minified and bundled.

4) Added Flask-Compress to send static files as compressed gzip. This will reduce network traffic and improve initial load time for pgAdmin.

5) Split few JS files to make code reusable.

6) Lazy load few modules like leaflet, wkx is required only if geometry viewer is opened. snapsvg loaded only when explain plan is executed. This will improve sqleditor initial opening time.

Below is the size and files difference after and before the changes:

Below is the lighthouse (Chrome extension) report after and before the changes:

      

Do not forget to do a yarn install and a pip install

Kindly review.

Move svgsnap, and its dependencies completely in separate module, and load them only when required (lazy loading).

Similarly - leaflet should be in a separate module, as not many user will use the Geometry Viewer.

They are lazy loaded in the UI component, but are bundled along with sqleditor JS. I'll separate them into a different JS file to further isolate.

Code is written to loading it lazily, but - bundles are not made like that.

Hence - whenever you load the sqleditor bundle, it will load all dependencies, which is not exactly expected in lazy loading.

Hi Hackers,

Attached is the updated patch to incorporate the reviews.

I'm finally able to lazy load chunks of JS ( leaflet, wkx, snapsvg, flotr2 - after a lot of hair pulling) as required to further reduce initial load time.

gzip will be done only in case of server mode as suggested. Below is the new structure of generated files (gzip will further reduce the size):

Kindly review.

Hi,

I've also added a yarn command in package.json - "yarn run bundle:analyze" which will generate an html report (webpack-bundle-analyzer) along with bundling for production.

Hi,

Seems like things are breaking :(

I had tested jasmine and API at least and were working fine.

Will send an updated patch.

Hi Aditya,

I have reviewed the patch and it works fine, however some of the review comments as below:

- Flask compress dependency is not included in the requirement.txt file in this patch, so giving error.

I had added that I remember :/

Bad miss :(

Added. 

- I have found 2 forms of sprintf in the code as below, can we make them identical?

      sprintf(gettext('Restore (%s: %s)'), node.label, data.label)

      pgadminUtils.sprintf('%s/%s', ref, encodeURI(o._id))

I checked this. The first one is imported in an ES6 syntax file, which allows only sprintf to be imported. The second one is in AMD file, where the complete file has to be imported. They cannot be identical.

Okay. 

Yeah, I will check what I can do on this.

- I couldn't find the way to test the Flask - Compress scenario, please let me know how to check

OK, so as per suggestions, Flask Compress is disabled in Desktop Mode. In the server mode, you can check the headers in network.

The Flask Compress Mode is disabled in Server Mode and working in Desktop Mode.

This condition is the culprit : if not config.DEBUG and not config.SERVER_MODE: 

- Webpack changes including lazy loading looks good to me,  however I couldn't find any performance improvement in lighthouse, may be because there are many parameters which are in consideration as per their report.

The problem with lighthouse is, it only checks the initial loading of the app. We have improved lazy loading in SQL editor, which is not even tested by lighthouse \_(- -)_/

Thank you, will send the updated patch.

Hi Aditya,

I have reviewed the patch and it works fine, however some of the review comments as below:

- Flask compress dependency is not included in the requirement.txt file in this patch, so giving error.

I had added that I remember :/

Bad miss :(

Added. 

- I have found 2 forms of sprintf in the code as below, can we make them identical?

      sprintf(gettext('Restore (%s: %s)'), node.label, data.label)

      pgadminUtils.sprintf('%s/%s', ref, encodeURI(o._id))

I checked this. The first one is imported in an ES6 syntax file, which allows only sprintf to be imported. The second one is in AMD file, where the complete file has to be imported. They cannot be identical.

Okay. 

Yeah, I will check what I can do on this.

- I couldn't find the way to test the Flask - Compress scenario, please let me know how to check

OK, so as per suggestions, Flask Compress is disabled in Desktop Mode. In the server mode, you can check the headers in network.

The Flask Compress Mode is disabled in Server Mode and working in Desktop Mode.

This condition is the culprit : if not config.DEBUG and not config.SERVER_MODE: 

- Webpack changes including lazy loading looks good to me,  however I couldn't find any performance improvement in lighthouse, may be because there are many parameters which are in consideration as per their report.

The problem with lighthouse is, it only checks the initial loading of the app. We have improved lazy loading in SQL editor, which is not even tested by lighthouse \_(- -)_/

Thank you, will send the updated patch.

Thanks,

I'm finally able to lazy load chunks of JS ( leaflet, wkx, snapsvg, flotr2 - after a lot of hair pulling) as required to further reduce initial load time.

gzip will be done only in case of server mode as suggested. Below is the new structure of generated files (gzip will further reduce the size):

Hi Hackers,

Attached is the patch to optimise webpack bundled files for improving performance. 

@Ashesh Vashi Thank you for your suggestions and inputs.

Changes include:

1) Remove underscore-string and sprintf-js packages as we were using only %s. Instead, added a function to do the same. Also changed gettext to behave like sprintf directly.

2) backgrid.sizeable.columns was not used anywhere, removed. @babel/polyfill is deprecated, replaced it with core-js.

3) Moved few css to make sure they get minified and bundled.

4) Added Flask-Compress to send static files as compressed gzip. This will reduce network traffic and improve initial load time for pgAdmin.

5) Split few JS files to make code reusable.

6) Lazy load few modules like leaflet, wkx is required only if geometry viewer is opened. snapsvg loaded only when explain plan is executed. This will improve sqleditor initial opening time.

Move svgsnap, and its dependencies completely in separate module, and load them only when required (lazy loading).

Similarly - leaflet should be in a separate module, as not many user will use the Geometry Viewer.

They are lazy loaded in the UI component, but are bundled along with sqleditor JS. I'll separate them into a different JS file to further isolate.

Code is written to loading it lazily, but - bundles are not made like that.

Hence - whenever you load the sqleditor bundle, it will load all dependencies, which is not exactly expected in lazy loading.
