* feat(webapp): migrate i18n extraction from mmjstool to @formatjs/cli
Replace custom mmjstool with industry-standard @formatjs/cli for i18n
message extraction. Adds support for localizeMessage as a recognized
extraction function and enables comprehensive ESLint rules for i18n.
Changes by area:
Dependencies (package.json):
- Add @formatjs/cli v6.7.4
- Remove @mattermost/mmjstool dependency
- Replace i18n-extract script with formatjs command
- Remove mmjstool-specific scripts (clean-empty, check-empty-src)
- Add i18n-extract:check for diff validation
Code (utils.tsx):
- Refactor localizeMessage to accept MessageDescriptor format
- Support {id, defaultMessage, description} parameters
- Maintain Redux store access (non-React context compatible)
- Add comprehensive JSDoc documentation
Linting (.eslintrc.json):
- Configure formatjs settings with additionalFunctionNames
- Enable 9 formatjs ESLint rules including enforce-id (error)
- Ensure all messages require explicit manual IDs
CI/CD (webapp-ci.yml):
- Simplify i18n check to formatjs extraction + diff
- Remove mmjstool and mobile-dir references
Context: Second attempt at PR #25830. Uses manual IDs only with
[id] placeholder pattern to enforce explicit ID requirements.
ESLint will catch missing IDs during development.
* chore(webapp): add temporary i18n reconciliation tooling
Add helper script to analyze conflicts between en.json and
defaultMessage values in code. This tooling will be reverted
after initial migration cleanup is complete.
Tooling added:
- scripts/i18n-reconcile-conflicts.js: Analyzes conflicts
- Detects spelling corrections
- Identifies placeholder mismatches
- Flags significant content changes
- Provides recommendations on which version to keep
- npm script: i18n-reconcile
Usage:
npm run i18n-reconcile
This will be reverted after reconciling the ~50 duplicate message
warnings and determining correct versions for conflicting messages.
* chore(webapp): upgrade eslint-plugin-formatjs and centralize formatjs deps
Move @formatjs/cli to root webapp package.json alongside other formatjs
dependencies for better monorepo organization. Upgrade eslint-plugin-formatjs
from 4.12.2 to 5.4.2 for latest features and bug fixes.
Changes:
- Upgrade eslint-plugin-formatjs: 4.12.2 → 5.4.2
- Move @formatjs/cli to webapp/package.json (from channels)
- Centralize formatjs tooling at monorepo root level
This provides:
- Better dependency management in monorepo
- Latest formatjs ESLint rules and features
- Consistent tooling across workspaces
* feat(webapp): make localizeMessage fully compatible with formatMessage API
Extend localizeMessage to accept a values parameter for placeholder
interpolation, making it fully compatible with react-intl's formatMessage API.
Remove the now-redundant localizeAndFormatMessage function.
Changes to localizeMessage:
- Add values parameter for {placeholder} interpolation
- Use getIntl() for proper ICU message formatting
- Support full formatMessage feature parity outside React contexts
- Update JSDoc with interpolation examples
- Mark as deprecated (prefer useIntl in React components)
Code cleanup:
- Remove localizeAndFormatMessage function (redundant)
- Migrate all localizeAndFormatMessage usages to localizeMessage
- Remove unused imports: getCurrentLocale, getTranslations
- Add getIntl import
Files migrated:
- notification_actions.tsx: notification.crt message
- app_command_parser_dependencies.ts: intlShim formatMessage
This consolidates i18n logic and provides a single, feature-complete
localization function for non-React contexts.
Example usage:
// Before (old function)
localizeAndFormatMessage(
{id: 'welcome', defaultMessage: 'Hello {name}'},
{name: 'John'}
)
// After (consolidated)
localizeMessage(
{id: 'welcome', defaultMessage: 'Hello {name}'},
{name: 'John'}
)
* refactor(i18n): remove intlShim abstraction, use IntlShape directly
Remove intlShim wrapper and use react-intl's IntlShape type throughout.
Key Changes:
- Remove intlShim constant from app_command_parser_dependencies.ts
- Update errorMessage() signature to accept IntlShape parameter
- Use IntlShape for intl properties in AppCommandParser and ParsedCommand
- Call getIntl() at function start in actions (command.ts, marketplace.ts)
- Pass IntlShape to AppCommandParser and doAppSubmit consistently
Files Modified:
- app_command_parser_dependencies.ts: Remove intlShim, update errorMessage
- app_command_parser.ts: Use IntlShape type
- command.ts, marketplace.ts: Call getIntl() early, pass to parser
- app_provider.tsx, command_provider.tsx: Use getIntl() in constructor
- apps.ts: Update doAppSubmit signature
Benefits: Better type safety, standard react-intl patterns, eliminates
unnecessary abstraction.
Context: Part of migration to @formatjs/cli tooling.
* refactor(webapp): remove deprecated t() function and refactor login validation
Remove the deprecated t() function that was used as a marker for the old
mmjstool extraction. With @formatjs/cli, this is no longer needed as
extraction happens directly from formatMessage calls.
Changes:
- Remove t() function definition from utils/i18n.tsx
- Remove t() import and marker calls from login.tsx
- Refactor login validation logic from multiple if statements to a clean
switch(true) pattern that evaluates boolean combinations directly
- Add helpful comments documenting the structure of login method combinations
- Add default case as safety fallback
The switch(true) pattern eliminates the need to build a key string and makes
the login method combination logic clearer and more maintainable.
Prompt: Remove deprecated t() translation marker function used by old mmjstool.
Refactor login validation from if blocks to switch(true) with boolean cases.
* refactor(i18n): share IntlProvider's intl instance with getIntl()
Make getIntl() return the same IntlShape instance that IntlProvider creates,
ensuring consistency between React components (using useIntl()) and non-React
contexts (using getIntl()).
Changes:
- Add intlInstance storage in utils/i18n.tsx
- Export setIntl() function to store the intl instance
- Modify getIntl() to return stored instance if available, with fallback to
createIntl() for tests and early initialization
- Add IntlCapture component in IntlProvider that uses useIntl() hook to
capture and store the intl instance via setIntl()
Benefits:
- Single source of truth: Both React and non-React code use the same IntlShape
- Consistent translations: No duplicate translation loading or potential desync
- Leverages IntlProvider's translation loading lifecycle automatically
- Maintains fallback for edge cases where IntlProvider hasn't mounted yet
Prompt: Refactor getIntl() to reuse IntlProvider's intl instance instead of
creating a separate instance, ensuring both React and non-React contexts use
the same translations and intl configuration.

* refactor(i18n): inline message ID constants for formatjs extraction
Replace dynamic ID references with literal strings to enable proper formatjs
extraction. Formatjs can only extract from static message IDs, not from
variables or computed IDs.
Changes:
- configuration_bar.tsx: Inline AnnouncementBarMessages constants to literal
string IDs ('announcement_bar.error.past_grace', 'announcement_bar.error.preview_mode')
- system_analytics.test.tsx: Replace variable IDs (totalPlaybooksID,
totalPlaybookRunsID) with literal strings ('total_playbooks', 'total_playbook_runs')
- password.tsx: Use full message descriptor from passwordErrors object instead
of dynamic ID with hardcoded defaultMessage. The errorId is still built
dynamically using template strings, but the actual message is looked up from
the passwordErrors defineMessages block where formatjs can extract it.
This eliminates all "[id]" placeholder entries from extraction output and
ensures all messages have proper extractable definitions.
Prompt: Fix dynamic message ID references that formatjs extraction can't parse.
Inline constants and use message descriptor lookups to enable clean extraction
without [id] placeholders.
* fix(i18n): add missing defaultMessage to drafts.tooltipText
The drafts.tooltipText FormattedMessage had an empty defaultMessage, causing
formatjs extraction to output an empty string for this message.
Added the proper defaultMessage with plural formatting for draft and scheduled
post counts.
Prompt: Fix empty defaultMessage in drafts tooltip causing extraction issues.
* feat(i18n): add --preserve-whitespace flag to formatjs extraction
Add the --preserve-whitespace flag to ensure formatjs extraction maintains
exact whitespace from defaultMessage values. This is important for messages
with intentional formatting like tabs, multiple spaces, or line breaks.
Prompt: Add --preserve-whitespace to i18n extraction to maintain exact formatting.
* feat(i18n): add custom formatjs formatter matching mmjstool ordering
Create custom formatter that replicates mmjstool's sorting behavior:
- Case-insensitive alphabetical sorting
- Underscore (_) sorts before dot (.) to match existing en.json ordering
- Simple key-value format (extracts defaultMessage)
The underscore-before-dot collation matches mmjstool's actual behavior and
reduces diff size by 50% compared to standard alphabetical sorting.
Changes:
- scripts/formatter.js: Custom compareMessages, format, and compile functions
- package.json: Use --format scripts/formatter.js instead of --format simple
Prompt: Create custom formatjs formatter matching mmjstool's exact sorting
behavior including underscore-before-dot collation to minimize migration diff.
* feat(i18n): enhance reconciliation script with git history metadata
Add git log lookups to show when each message was last modified in both
en.json and code files. This enables data-driven decisions about which
version to keep when resolving conflicts.
Enhancements:
- getEnJsonLastModified(): Find when an en.json entry last changed
- findCodeFile(): Locate source file for a message ID (handles id= and id:)
- getCodeLastModified(): Get last modification date for source files
- Caching for performance (minimizes git operations)
Output includes:
📅 en.json: [date] | [hash] | [commit message]
📅 code: [date] | [hash] | [commit message]
📂 file: [source file path]
Analysis shows en.json entries from 2023 while code actively updated
2024-2025, indicating code is more authoritative.
Prompt: Add git history to reconciliation report showing modification dates
for data-driven conflict resolution decisions.
* feat(i18n): add optional duplicate message ID check script
Add i18n-extract:check-duplicates script that fails if the same message ID
has different defaultMessages in multiple locations. This is kept as an
optional standalone script rather than auto-chained with i18n-extract to
allow the migration to proceed while duplicates are addressed separately.
Usage:
npm run i18n-extract:check-duplicates
The script runs formatjs extract to /dev/null and checks stderr for
"Duplicate message id" warnings, failing if any are found.
Prompt: Add optional duplicate ID check as standalone npm script for gradual
migration without blocking on existing duplicate message IDs.
