This job fetches tweets from the Twitter API, processes them through our filtering pipeline, and stores them in the database. The scheduler runs this job at regular intervals to ensure timely and consistent data updates.\n\n## Val Town Cron Configuration\n\nAs per the [Val Town documentation](https://docs.val.town/quickstarts/first-cron/), cron schedules cannot be configured programmatically via code. Instead, they must be set up through the Val Town web GUI.\n\n### Steps to Configure the Scheduler\n\n1. **Upload the Cron File**:\n - Ensure the `twitter-fetch.cron.ts` file is uploaded to your Val Town account\n - The file should have the `.cron.ts` extension to indicate it's a cron job\n\n2. **Configure Schedule in Val Town Web GUI**:\n - Log in to your Val Town account\n - Navigate to the `twitter-fetch.cron.ts` val\n - Look for the \"Schedule\" or \"Cron\" settings in the val's interface\n - Set the desired schedule using cron syntax (e.g., `0 */3 * * *` for every 3 hours)\n\n3. **Recommended Schedule**:\n - For production use, we recommend running the job every 1-3 hours (`0 */1 * * *` to `0 */3 * * *`)\n - For testing or development, you might want to run it more frequently\n - Consider Twitter API rate limits when setting the schedule\n\n## Environment Variables\n\nThe cron job requires the following environment variables to be set in your Val Town environment:\n\n- `TWITTER_BEARER_TOKEN`: Your Twitter API bearer token\n- `EMAIL_TO` (optional): Email address to send notifications to\n- `AUTH_USERNAME` and `AUTH_PASSWORD`: Credentials for accessing the test endpoints\n- `TWITTER_FILTER_*` (optional): Various filter configuration options\n\n## Monitoring and Logs\n\n- The cron job logs its activity to the Val Town console\n- If configured, it sends email notifications about successful runs and errors\n- You can view the logs in the Val Town interface for the val\n\n## Troubleshooting\n\n- If the job fails due to rate limiting, it will automatically retry with exponential backoff\n- Error emails include detailed information about the failure\n- Check the Val Town logs for more detailed error messages\n\n## Manual Triggering\n\nFor testing or one-off runs, you can manually trigger the cron job using the test endpoint:\n\n```\nhttps://your-val-town-username.web.val.run/twitter-test\n```\n\nThis endpoint requires basic authentication using the `AUTH_USERNAME` and `AUTH_PASSWORD` environment variables.

Instead of traditional migration frameworks, we use a table versioning approach for schema changes.\n\n### Table Versioning Approach\n\n1. **Version Suffix in Table Names**\n - All tables include a version suffix (e.g., `topics_v1`)\n - When schema changes are needed, create a new table with an incremented version (e.g., `topics_v2`)\n\n2. **Data Migration Process**\n - Create the new table with the updated schema\n - Copy data from the old table to the new table, mapping columns as needed\n - Update the `TABLES` constant in `migrations.ts` to point to the new table versions\n - Deploy the updated code\n\n3. **Utility Functions**\n - `tableExists(tableName)`: Check if a table exists in the database\n - `getTableColumns(tableName)`: Get column information for a table\n - `migrateTable(oldTableName, newTableName, createTableSql, columnMappings)`: Migrate data between tables\n\n### Example Schema Change\n\nTo add new columns to the topics table:\n\n```typescript\n// 1. Create a migration function\nasync function upgradeTopicsToV2() {\n const oldTable = \"topics_v1\";\n const newTable = \"topics_v2\";\n \n // Define the new table schema with additional columns\n const createTableSql = `\n CREATE TABLE IF NOT EXISTS ${newTable} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n title TEXT NOT NULL,\n description TEXT,\n created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n is_active BOOLEAN DEFAULT 1, -- New column added in v2\n color TEXT DEFAULT '#3498db' -- New column added in v2\n )\n `;\n \n // Migrate the table\n await migrateTable(oldTable, newTable, createTableSql);\n}\n\n// 2. Update the TABLES constant after migration\nexport const TABLES = {\n TOPICS: \"topics_v2\", // Updated to v2\n POSTS: \"posts_v1\",\n // ...other tables\n};\n```\n\n### Handling Column Renames\n\nWhen renaming columns, provide a mapping in the migration function:\n\n```typescript\n// Column mappings for renamed columns\nconst columnMappings = {\n \"author\": \"author_name\",\n \"platform\": \"source\",\n \"created_at\": \"published_at\"\n};\n\n// Use the mappings in the migration function\nawait migrateTable(oldTable, newTable, createTableSql, columnMappings);\n```\n\n### Best Practices\n\n1. **Always increment version numbers** - Never reuse a table name for a different schema\n2. **Test migrations thoroughly** - Verify data integrity after migration\n3. **Deploy schema changes separately** from application logic changes when possible\n4. **Document schema changes** in code comments and commit messages\n5. **Update all affected queries** when changing table or column names\n6. **Create appropriate indexes** for new tables and columns\n\n## Usage\n\nThe database module is automatically initialized when imported. For production deployments, you may want to comment out the auto-initialization for better performance in serverless environments:\n\n```typescript\n// Comment this out in production if you want to initialize manually\n// for better performance in serverless environments\ninitializeDatabase().catch(console.error);\n```",[],[177,534,151],"06a4db3c-55f5-11f0-9d32-f69ea79377d9",11,["D",1751317131524],[194,195,196,197,198],[177,534],["D",1751316325838],[193,199,201,203,204,205,206,207,208,209,210,211,212,213,214,215,216,217,218,219,220,221],[177],["D",1751316115780],{"_96":95,"_103":99},{"_96":95,"_97":-5,"_98":99,"_18":54,"_100":101,"_102":24},{"_13":85,"_31":86,"_42":41,"_87":43,"_88":-5,"_89":-5,"_90":-5,"_91":-5,"_92":-5,"_93":44,"_94":95},"ctx",{"_78":-5,"_122":610,"_611":612,"_613":614,"_615":24,"_616":24,"_617":24,"_618":58,"_619":-5,"_620":-7,"_621":-7,"_622":139,"_623":24,"_624":24,"_625":-5,"_626":24,"_627":24,"_628":24,"_629":-5},"ENV",{"_581":582,"_583":584,"_585":86,"_586":587,"_588":589,"_590":591,"_592":593,"_594":595,"_596":597,"_598":599,"_600":601,"_602":603,"_604":605,"_606":607,"_608":609},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","71c1b20804b3232a7e513be260cfffc1932a9e97","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
