## Description:
Only mentioning removals/major updates/notable changes below, not all
minor upgrades.
### Removed:
- "@aws-sdk/client-s3": not used anywhere (was used in Archive.ts
previously)
- chai, "@types/chai", sinon-chai: not used anywhere, probably leftover.
Vitest uses a bundled version of Chai for its expect asserations under
the hood too.
- protobufjs, "@types/google-protobuf": not used anywhere, probably left
from evan's experiment with it? Removed from vite.config.ts too.
- "@types/jquery": not used anywhere, probably leftover
- sinon, "@types/sinon": not used anywhere just like chai, probably
leftover. And Vitest provides us with the same functionality.
- "@types/systeminformation": dependency systeminformation was removed
last year, this is an unneeded, deprecated and unmaintained remainder.
- vite-tsconfig-paths: removed, and removed the import and usage in
vite.config.ts and replaced it by adding `tsconfigPaths: true` to the
`resolve` block. Because of this message displayed on running the tests:
"The plugin "vite-tsconfig-paths" is detected. Vite now supports
tsconfig paths resolution natively via the resolve.tsconfigPaths option.
You can remove the plugin and set resolve.tsconfigPaths: true in your
Vite config instead."
- vite-plugin-static-copy: removed, we don't use it anymore (was used in
our vite.config.ts once,, probably before Vite natively supported
copying static assets via its publicDir configuration)
### Updated:
- color.js: v0.5 > v0.6, no breaking change affecting us
- cross-env: v7 > v10. It's a publicly archived repo since Nov 2025. But
before that he got it up-to-date from June 2025, porting to TS, dropping
old Node versions, dependencies etc. Seems still good to use for some
amount of time to come.
- dotenv: v16 > v17, now logs an informational message by default when
it loads an environment file. Can be disabled by using
dotenv.config({quite: true}) if needed.
- ejs: v3 > v5: security patches mostly. Vite still uses v3 btw.
- eslint: v9 > v10. Newly enabled rules by default:
'no-unassigned-vars', 'no-useless-assignment' and
'preserve-caught-error'. Mostly faster and minimum support moved to
higher node versions, which shouldn't be a problem.
- "@eslint/compat": v1 > v2. Minimum supported Node versions, which
should not be a problem.
- intl-messageformat: v10 > v11 no breaking changes that affect us
- jdom: v27 > v29. Faster. Most notably minimum support moved to higher
node v22 version, which should not be a problem. Also, see types/node,
kind of expecting v24 to be installed now.
- nanoid: from v3 to v5, no breaking changes that affect us
- "@opentelemetry/sdk-logs": now that addLogRecordProcessor is removed,
changed Logger.ts to pass an (empty) provider array directly to the
LoggerProvider constructor. Follows the changes in
https://github.com/open-telemetry/opentelemetry-js/pull/5588
- "@tailwindcss/vite": supports vite v8 from 4.2.2, and a fix for it in
4.2.4
- tailwindcss: supports vite v8 from 4.2.2
-- in 4.1.15 (we were already above this version) break-words was
deprecated in favor of wrap-break-word. But break-words, which we use in
15 places, will still work as expected
(https://github.com/tailwindlabs/tailwindcss/pull/19157). Same goes for
also deprecated "order-none".
- "@types/node": from v22 to v24, assuming most now use node 24
- vite v7 > v8:
-- is now on 8.0.10 so first bugs are out of it, while v8 itself also
fixed a big number of bugs.
-- in vite.config.ts, fixed Ts error/compilation issue by changing the
manualChunks option in build.rollupOptions.output to use the function
syntax, which is required by the updated types instead of the object
syntax.
- zod: no changes that affect us
### Prettier:
Updated only because of (new because of update?) Prettier errors for
files untouched in this PR originally:
- PathFinder.Parabola.ts
- WorkerMessages.ts
- ClanModal.handlers.test.ts
- ClanModal.rendering.test.ts
- CONTRIBUTING.md
- README.md
### ESLint:
Fixes needed to silence errors coming from newly enabled recommended
rules 'no-useless-assignment' and 'preserve-caught-error':
For 'no-useless-assignment' (default assignment never used because of
unreachable code or they are guaranteed to get a value, so they can be
undefinedat the start. Exception was AttackExecution, so made the
default value of 0 the default case in the switch statement):
- ClientGameRunner
- GameModeSelector
- NameBoxCalculator
- StructureDrawingUtils
- TerritoryLayer
- Diagnostics
- GameRunner
- ColorAllocator
- DefaultConfig
- AttackExecution
- AiAttackBehavior
- Worker.worker
- GamePreviewBuilder
For 'preserve-caught-error', disabled the rule here because the possible
fix `{cause: error}` was introduced in ES2022 while we're still on
target ES2020 currently:
- GameServer
- Privilege
_Error: The value assigned to 'gameMap' is not used in subsequent
statements. (no-useless-assignment)

statements. (no-useless-assignment)

statements. (no-useless-assignment)
Error: The value assigned to 'description' is not used in subsequent
statements. (no-useless-assignment)
Error: There is no `cause` attached to the symptom error being thrown.
(preserve-caught-error)
Error: There is no `cause` attached to the symptom error being thrown.
(preserve-caught-error)_
All tests pass. TypeScript and ESLint errors resolved.
