# Introduction
Lately encountering a lot of out of memory error when running
twenty-front in watch mode with both TypeScript and lint checkers
```ts
Error: Worker terminated due to reaching memory limit: JS heap out of memory
at new NodeError (node:internal/errors:405:5)
at [kOnExit] (node:internal/worker:287:26)
at Worker.<computed>.onexit (node:internal/worker:209:20)
```
The existing configuration looks like this:
```ts
// packages/twenty-front/vite.config.ts
'cd ../.. && eslint packages/twenty-front --report-unused-disable-directives --max-warnings 0 --config .eslintrc.cjs',
```
This is wrong as computing the root eslintrc completely omitting
twenty-front's one ***and its ignorePattern*** so will be checking in
`node_modules` etc checking for project-structure :).
For example this a
[snippet](https://gist.github.com/prastoin/d7f8ad4ef5eb2f7732209b756a38094c)
of the above commands errors. We can see rule that should be disabled by
`eslintrc.react.cjs` extension made from twenty-front `eslintrc` :
```ts
/Users/paulrastoin/ws/twenty-two/packages/twenty-front/src/modules/settings/data-model/fields/forms/components/__stories__/SettingsDataModelFieldSettingsFormCard.stories.tsx
23:27 warning Forbidden non-null assertion @typescript-eslint/no-non-null-assertion
```
## Fixes
- consume the `twenty-front` package eslint configuration within the
vite lint checker
- eslint overrides extends are getting merged based on glob inclusion of
their files declarations
- any linted files should be included in one of our `tsconfig`
- removed redundant and counter-productive negative `ignorePatterns`, as
eslint will naturally only lint files within configuration file
directory by default which will result making it go through local
`node_modules` project structure
## Now
Less cpu usage <3.5 gb and faster
```ts
// from packages/twenty-front
TIMING=1 npx eslint . --report-unused-disable-directives --max-warnings 0 --config .eslintrc.cjs --debug
#...

## Conclusion
Please note that `nx linter` might not be as strict as vite config
eslint runner
