Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 171.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

object access via string literals is disallowed
Open

    resolver: (results, query) => results.find((result) => result.id === query.id)!["result"],
Severity: Minor
Found in web/src/context/GraphqlBatcher.tsx by tslint

Rule: no-string-literal

Forbids unnecessary string literal property access. Allows obj["prop-erty"] (can't be a regular property access). Disallows obj["property"] (should be obj.property).

Rationale

If --noImplicitAny is turned off, property access via a string literal will be 'any' if the property does not exist.

Notes
  • Has Fix

Config

Not configurable.

Examples
"no-string-literal": true
