test: prepare lint and Vitest for TypeScript 7 by BridgeAR · Pull Request #9345 · DataDog/dd-trace-js

BridgeAR · 2026-07-14T17:37:55Z

Summary

TypeScript 7 exposes two compatibility issues before the dependency update can land. SonarJS 4.1 crashes while loading compiler enums that TypeScript 7 removed, and Vitest 3 picks up the repository tsc from npm's inherited PATH instead of the sandbox's pinned compiler. This updates SonarJS to the release that pins a compatible compiler and makes the Vitest fixture invoke its sandboxed tsc directly.

Refs: #9327

SonarJS 4.1 reads compiler enums removed in TypeScript 7 and crashes before ESLint can run.

Vitest 3 resolves a bare tsc command from the inherited npm PATH, which made sandboxed typechecks use the repository compiler instead of their pinned dependency.

More details

PR is a correct preparation for TypeScript 7 compatibility: updates sonarjs to pin a TS-compatible version and makes Vitest's typecheck use the sandboxed tsc directly instead of PATH resolution. Both changes are minimal, necessary, and carry no behavioral risks.

Benchmarks

Benchmark execution time: 2026-07-14 17:52:29

Comparing candidate commit aae8006 in PR branch BridgeAR/2026-07-14-typescript-7-compat with baseline commit c5edb32 in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 0 performance regressions! Performance is the same for 2310 metrics, 48 unstable metrics.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

🟩 = significantly better candidate vs. baseline
🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'

Unstable benchmarks

These benchmarks have a confidence interval too wide to call a change; treat them as noise rather than signal.
