How do I disable TSLint Rule: This rule requires the `strictNullChecks` compiler option to be turned on to function correctly

Question

I am in the middle of upgrading our app and I'm getting the following error when i try to build my angular app: This rule requires the strictNullChecks compiler option to be turned on to function correctly @typescript-eslint/no-unnecessary-condition

The problem is that I want "strictNullChecks" to be set to false so that I don't have to refactor the whole application until a later date. Is there a way to turn off this rule? I can't seem to find any documentation on this. I'm getting this same error about 2100 times. Anyone help would be appreciated.

I have tried adding the following to my angularCompilerOptions but that did not resolve my issue: allowRuleToRunWithoutStrictNullChecksIKnowWhatIAmDoing: true

Answer 1

I made next 3 steps to eliminate that error

1. Added to .eslintrc.js into rules section

"@typescript-eslint/strict-boolean-expressions": "warn"

2. Added to tsconfig.json into jsoncompilerOptions section

"strictNullChecks": true

3. Reloaded my IDE
