Lazy lading rules experiment

lazyLoad.md

Here is my project structure:

app
  - makefile.js
  - test.js
  - test
     - app.js
     - app1
       -- app1.js

Here is how I measured the eslint run using the Makefile concept.

console.time("Makefile run");
nodeCli.exec("eslint", "./");
console.timeEnd("Makefile run");

Runs

With 5 rules active

Regular loading

Makefile run: 958ms

Lazy loading

Makefile run: 830ms

With 41 rules active

Regular loading

Makefile run: 989ms

Lazy loading

Makefile run: 882ms

With ALL rules active

Regular loading

Makefile run: 1173ms

Lazy loading

Makefile run: 1128ms

Notes

• If we only require the config-initializer module only when someone has the init flag on then we save 70ms. So basically from the above times just subtract 70ms.
  • The reason is inquirer module load time is high
• This can be achieved with minimum changes.
