Warning: Potential spacing issues when dynamically adjusting Material UI Grid using Typescript

When working with Typescript, I encountered an error related to spacing values:

TS2322: Type 'number' is not assignable to type 'boolean | 7 | 2 | 10 | 1 | 3 | 4 | 5 | 6 | 8 | "auto" | 9 | 11 | 12'.
No lint errors found
Version: typescript 3.5.2, tslint 5.14.0

I needed to dynamically set the xl, lg, ... and so on properties while iterating over an array:

<Grid container spacing={2}>
  {row.map(resumeItem =>
     <Grid key={resumeItem.id} item xs={12} lg={6} xl={resumeItem.space}>
       ...
     </Grid>
   )}
</Grid>

It's worth mentioning that the space property is always a number!

Answer №1

If you are encountering this typescript error, it could be due to the fact that the space property allows any number, while the xl prop only accepts a specific range of numbers (specifically, integers from 1 to 12). For instance, assigning the number '17.2' to space is valid, but it would not be permitted for the xl prop.

To resolve this issue, consider modifying your type definition of Number for the space property to match that of the xl prop, like so:

space: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12

Keep in mind that this adjustment may have implications elsewhere in your code depending on how values are assigned. Alternatively, you could follow the suggestion of casting space as any, but be aware that this essentially disables type checking for this instance and eliminates Typescript's ability to detect incompatible values passed to xl. Ultimately, decide whether this tradeoff is acceptable for your project.

Answer №2

I appreciate everyone who has contributed. When attempting to implement this strategy:

range: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

The issue remains unresolved. Trying an ad hoc solution did not work either, so I have resorted to using the any method for now.

Many thanks!
