Search Reddit for specific keywords within a defined time range.\n2. Send notifications to your preferred platform (Discord, Slack, email, etc.)\n\nReddit does not have an API that allows users to scrape data, so we are doing this with the Google Search API, [Serp](https://serpapi.com/). \n\n---\n\n## Example\nThis val tracks mentions of \"Val Town\" and related terms on Reddit, filtering results from the last 7 days and sending alerts to a Discord webhook. \n![Screenshot 2025-01-10 at 5.13.16 PM.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/beecb766-824e-4672-8393-3abd2edb1c00/public)\n\n---\n\n## Set Up\n\n### 1. Fork this Val\nTo start using this template, fork this val by clicking the fork button at the top-right corner of the page.\n![Screenshot 2025-01-10 at 1.22.10 PM.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/c4ae349d-7e28-4378-8646-21c8958e1f00/public)\n\n---\n### 2. View Source Code\nThe `CODE` box shows you the the full source code of this val, you may need to scroll down to see it.\n![image.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/6a4dabb4-3b27-4cea-fce3-95a1a1c3cd00/public)\n\n---\n### 3. Get a SerpApi Key\nThis template requires a [SerpApi](https://serpapi.com/) key to search Reddit posts via Google search results.\n\n1. **Get a SerpApi key**:\n - Sign up at [SerpApi](https://serpapi.com/) to create an account.\n - Generate an API key from your account dashboard.\n\n2. **Add the SerpApi key to your environment variables**:\n - Go to your [Val Town environment variables](https://www.val.town/settings/environment-variables).\n - Add a new key:\n - Key: `SERP_API_KEY`\n - Value: Your SERP API key.\n\nWithout this key, the val will not function correctly.\n\n---\n### 4. Customize Keyword\nIn the `CODE` box below, update the terms or phrases you want to track:\n```const KEYWORDS = \"\\\"node\\\" OR \\\"node.js\\\"\";```\n\n---\n\n### 5. Set Up Your Notification Method\nThis template uses a Discord webhook for notifications. You can update this to your preferred platform:\n\n**Create a Discord webhook following [this guide](https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks).**\nSave your webhook URL in your Val Town environment variables (you can find this on the left sidebar):\n- Key: `mentionsDiscord`\n- Value: Your Discord webhook URL.\nNotifications will be sent using this function:\n```\n await discordWebhook({\n url: Deno.env.get(\"mentionsDiscord\"),\n content,\n });\n```\n\nTo switch to another platform (e.g., Slack, email, or custom webhooks), replace the discordWebhook call with the appropriate integration ((e.g., [`@std/email`](https://docs.val.town/std/email/), [Slack](https://docs.val.town/integrations/slack/send-messages-to-slack/), or [anywhere else](https://docs.val.town/guides/creating-a-webhook/))\n\n---\n\n#### 🎉 Congrats! You now have a val running that ensures you never miss another Reddit mention. 🎉\n\n---\n\n### NOTE: Usage Limits\n- **SerpApi:** Free SerpApi accounts have monthly call limits.",[150],"pulls","branches","forks","envVars",{"_164":166,"_167":60},"connections",{"_164":60,"_165":60},"count","unfilledCount",2,"emptyCount",{"_43":149,"_32":150,"_30":151,"_143":-5,"_41":42,"_40":152,"_144":153,"_38":174,"_13":60,"_33":20,"_35":155,"_24":25,"_147":-5,"_171":175,"_27":176},{"_43":142,"_32":28,"_30":31,"_143":-5,"_41":42,"_40":14,"_144":25,"_38":170,"_13":146,"_33":37,"_35":36,"_24":25,"_147":-5,"_171":172,"_27":173},["D",1763049119127],"children",[],[28],["D",1762464182146],[],[150],["D",1762464182146],{"_98":97,"_105":101},{"_98":97,"_99":-5,"_100":101,"_18":54,"_102":103,"_104":25},{"_13":83,"_32":84,"_43":42,"_85":44,"_86":87,"_88":89,"_90":50,"_91":92,"_93":94,"_95":45,"_96":97},"ctx",{"_76":-5,"_127":214,"_215":216,"_217":218,"_219":25,"_220":25,"_221":25,"_222":153,"_223":-5,"_224":-7,"_225":-7,"_226":60,"_227":25,"_228":25,"_229":-5,"_230":25,"_231":25,"_232":25,"_233":-5},"ENV",{"_185":186,"_187":188,"_189":84,"_190":191,"_192":193,"_194":195,"_196":197,"_198":199,"_200":201,"_202":203,"_204":205,"_206":207,"_208":209,"_210":211,"_212":213},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","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"]
