The server\ntalks to MongoDB through an async driver. The client runs Minimongo, an\nin-memory synchronous Mongo emulator that holds the documents that\nsubscriptions have shipped.\n\n## Decision flow\n\n1. Where does this code run?\n   - Server-only: use `await Collection.*Async(...)`.\n   - Client-only: use `Collection.*(...)` synchronously.\n   - Isomorphic (`import` in shared code): use `await Collection.*Async(...)`.\n     On the client the work is local but still Promise-based; on the server it\n     talks to Mongo.\n2. Does the query select more than a page of documents? Add `{ limit, skip }`\n   and an index that matches the selector.\n3. Are you reading from a publication on the client? Use `find().fetch()`\n   (sync) without `await`. The data is already local.\n\n## Server reads\n\n```javascript\nconst doc  = await Posts.findOneAsync(id);\nconst list = await Posts.find({ ownerId }, {\n  fields: { title: 1 }, sort: { createdAt: -1 }, limit: 50,\n}).fetchAsync();\nconst count = await Posts.find({ ownerId }).countAsync();\n```\n\n## Server writes\n\n```javascript\nconst _id = await Posts.insertAsync({ title, ownerId });\nawait Posts.updateAsync({ _id }, { $set: { title } });\nawait Posts.removeAsync({ _id });\n```\n\n## Client reads (Minimongo)\n\nThe async API is isomorphic. Prefer it in shared code so the same line works\non the server.\n\n```javascript\nconst doc = await Posts.findOneAsync(id);                 \u002F\u002F works in shared\u002Fclient\u002Fserver\nconst list = await Posts.find({ ownerId }).fetchAsync();\n```\n\nOn the client, the operation reads in-memory Minimongo but the async API still\nreturns a real Promise. Code after `await` resumes in a later microtask. The\nsync API also works client-side, but only there:\n\n```javascript\nconst doc = Posts.findOne(id);                            \u002F\u002F client-only\nconst list = Posts.find({ ownerId }).fetch();             \u002F\u002F client-only\n```\n\nPick sync when the calling scope is naturally sync and forcing `await`\nwould cascade async into a render path. Common cases:\n\n- React render functions and hooks that consume reactive data.\n- Blaze template helpers.\n- Tracker autoruns.\n\nPick async (`findOneAsync`, `fetchAsync`) when the file might also run on\nthe server, or the containing function is already `async`.\n\n## Indexes\n\nIndexes are server-side. Create them on app startup:\n\n```javascript\nimport { Meteor } from \"meteor\u002Fmeteor\";\nimport { Posts } from \"\u002Fimports\u002Fapi\u002Fposts\";\n\nMeteor.startup(async () => {\n  await Posts.createIndexAsync({ ownerId: 1, createdAt: -1 });\n  await Posts.createIndexAsync({ slug: 1 }, { unique: true });\n});\n```\n\nChoose compound-index key order from equality filters, sort fields, range\nfilters, and usable index prefixes. The JavaScript property order in an\nequality selector does not have to match the index. Verify the chosen plan in\nthe Mongo shell (`meteor mongo`) with\n`db.posts.find(...).explain(\"executionStats\")`.\n\n## Reactivity source: oplog or change streams\n\nThe core driver boundary is release-specific:\n\n| Meteor | Reactive behavior |\n|---|---|\n| 3.0 through 3.4 | Uses oplog when `MONGO_OPLOG_URL` is configured; otherwise polling. Core change streams and reactivity-order settings are unavailable. |\n| 3.5+ | Chooses a driver per query in the default order below. |\n\nMeteor 3.5+ defaults to:\n\n```text\nchangeStreams -> oplog -> polling\n```\n\nChange streams require MongoDB 6+ on a replica set or sharded cluster, an\nunordered observer, no `skip` or `limit`, and a selector Minimongo can compile.\nAn ineligible query falls through to the next configured driver. Oplog is\navailable only when `MONGO_OPLOG_URL` is configured.\n\nOn Meteor 3.5+, override the app-wide order with\n`METEOR_REACTIVITY_ORDER=oplog,polling` or:\n\n```json\n{\n  \"packages\": {\n    \"mongo\": {\n      \"reactivity\": [\"oplog\", \"polling\"]\n    }\n  }\n}\n```\n\nOn Meteor 3.5+, the `disable-oplog` package removes only the oplog step. It\ndoes not disable change streams. Use `reactivity: [\"polling\"]` to force\npolling. On Meteor 3.0 through 3.4, do not add these settings; upgrade first.\n\n## Collation (Meteor 3.5+)\n\nUse `collation` for locale-aware or case-insensitive selectors and sorting on\nboth Mongo and Minimongo. Back the server query with an index created using\nthe same collation:\n\n```javascript\nconst collation = { locale: \"en\", strength: 2 };\nconst users = await Users.find(\n  { email: \"Alice@Example.COM\" },\n  { collation },\n).fetchAsync();\n\nawait Users.createIndexAsync({ email: 1 }, { collation });\n```\n\nMinimongo supports `locale`, strength 1 through 3, `caseLevel`,\n`numericOrdering`, and `caseFirst`. Other Mongo collation options are\nserver-only and are ignored by Minimongo.\n\n## Anti-patterns\n\n- Use sync Mongo on the server. Removed in Meteor 3.\n- Use sync Mongo (`findOne`, `insert`, `update`, `remove`) in shared code.\n  Breaks the moment the file is imported on the server.\n- Unbounded `find` on the server. Always `limit`.\n- Forget `fields` projection when publishing. Always project.\n- Assume the async Minimongo API resumes inline. It returns a Promise even\n  though the underlying read is local.\n\n## See also\n\n- `references\u002Fserver-vs-client.md`\n- `references\u002Fselectors-modifiers.md`\n- `references\u002Feval-cases.md`\n",{"data":40,"body":50},{"name":4,"description":6,"metadata":41,"license":26},{"author":8,"kind":42,"meteor":43,"area":44,"tagline":45,"bundle":46,"docs_synced_at":49},"knowledge",">=3.0","data","Write and debug Mongo queries in Meteor 3 (server async vs Minimongo, oplog vs change streams, indexes, selectors, modifiers).",[47,48],"essentials","fullstack","2026-08-25",{"type":51,"children":52},"root",[53,62,68,75,170,176,497,503,695,701,706,827,839,956,968,986,1012,1018,1023,1328,1348,1354,1359,1420,1425,1435,1463,1476,1629,1650,1656,1669,1923,1959,1965,2042,2048,2078],{"type":54,"tag":55,"props":56,"children":58},"element","h1",{"id":57},"mongo-and-minimongo",[59],{"type":60,"value":61},"text","Mongo and Minimongo",{"type":54,"tag":63,"props":64,"children":65},"p",{},[66],{"type":60,"value":67},"Meteor ships two implementations of the Mongo API in one codebase.
