message broker: Send notifications with arbitrary payloads from one database client to others.\n\nWorks with node.js 8+ and plain JavaScript or TypeScript 3. Uses the Postgres [`NOTIFY`](https://www.postgresql.org/docs/10/static/sql-notify.html) statement and subscribes to notifications using [`LISTEN`](https://www.postgresql.org/docs/10/static/sql-listen.html).\n\n### Features\n\n 📡 Send and subscribe to messages\n\n ⏳ Continuous connection health checks\n\n ♻️ Reconnects automatically\n\n ❗️ Proper error handling\n\n 👌 Type-safe API\n\n---\n\n\n## Installation\n\n```sh\n# using npm:\nnpm install pg-listen\n\n# using yarn:\nyarn add pg-listen\n```\n\n\n## Usage\n\n```js\nimport createSubscriber from \"pg-listen\"\nimport { databaseURL } from \"./config\"\n\n// Accepts the same connection config object that the \"pg\" package would take\nconst subscriber = createSubscriber({ connectionString: databaseURL })\n\nsubscriber.notifications.on(\"my-channel\", (payload) => {\n // Payload as passed to subscriber.notify() (see below)\n console.log(\"Received notification in 'my-channel':\", payload)\n})\n\nsubscriber.events.on(\"error\", (error) => {\n console.error(\"Fatal database connection error:\", error)\n process.exit(1)\n})\n\nprocess.on(\"exit\", () => {\n subscriber.close()\n})\n\nexport async function connect () {\n await subscriber.connect()\n await subscriber.listenTo(\"my-channel\")\n}\n\nexport async function sendSampleMessage () {\n await subscriber.notify({\n greeting: \"Hey, buddy.\",\n timestamp: Date.now()\n })\n}\n```\n\n\n## API\n\nFor details see [dist/index.d.ts](./dist/index.d.ts).\n\n\n## Error & event handling\n\n### `instance.events.on(\"error\", listener: (error: Error) => void)`\n\nAn `error` event is emitted for fatal errors that affect the notification subscription. A standard way of handling those kinds of errors would be to `console.error()`-log the error and terminate the process with a non-zero exit code.\n\nThis `error` event is usually emitted after multiple attempts to reconnect have failed.\n\n### `instance.events.on(\"notification\", listener: ({ channel, payload }) => void)`\n\nEmitted whenever a notification is received. You must have subscribed to that channel before using `instance.listenTo()` in order to receive notifications.\n\nA more convenient way of subscribing to notifications is the `instance.notifications` event emitter.\n\n### `instance.events.on(\"reconnect\", listener: (attempt: number) => void)`\n\nEmitted when a connection issue has been detected and an attempt to re-connect to the database is started.\n\n### `instance.notifications.on(channelName: string, listener: (payload: any) => void)`\n\nThe convenient way of subscribing to notifications. Don't forget to call `.listenTo(channelName)` to subscribe the Postgres client to this channel in order to receive notifications.\n\n\n## Why another package?\n\nIn one sentence: Because none of the existing packages was working reliably in production.\n\nUsing the `NOTIFY` and `LISTEN` features is not trivial using [`node-postgres` (`pg`)](https://www.npmjs.com/package/pg), since you cannot use connection pools and even distinct client connections also tend to time out.\n\nThere are already a few packages out there, like `pg-pubsub`, but neither of them seems to work reliably. Errors are being swallowed, the code is hard to reason about, there is no type-safety, ...\n\nThis package aims to fix those shortcomings. Postgres LISTEN & NOTIFY in node that finally works.\n\n\n## Debugging\n\nSet the `DEBUG` environment variable to `pg-listen:*` to enable debug logging.\n\n\n## License\n\nMIT\n","readmeFilename":"README.md","gitHead":"b2bee3c158a2a0e6b7d8c194f49f027d30ac2aca","bugs":{"url":"https://github.com/andywer/pg-listen/issues"},"homepage":"https://github.com/andywer/pg-listen#readme","_id":"pg-listen@1.0.0-with-cjs-hack","_npmVersion":"6.5.0","_nodeVersion":"10.13.0","_npmUser":{"name":"andywer","email":"andy.dev@next-step-software.com"},"dist":{"integrity":"sha512-bBqDARkiLRGr1yGmS3YOHFvOW9ZMRvLY9EGtN1qvlGAR2ugzWvikt837q9A2K0P3dFEXtEp9pTnAgMGuLHHAng==","shasum":"00d936508cc9e7c8ae43d9f428e9cbfd16bcbc83","tarball":"https://registry.npmjs.org/pg-listen/-/pg-listen-1.0.0-with-cjs-hack.tgz","fileCount":8,"unpackedSize":23857,"npm-signature":"-----BEGIN

--write","git add"]},"readme":"# pg-listen - Postgres LISTEN & NOTIFY that works\n\n[](https://travis-ci.org/andywer/pg-listen) [](https://www.npmjs.com/package/pg-listen)\n\nPostgreSQL can act as a message broker: Send notifications with arbitrary payloads from one database client to others.\n\nWorks with node.js 8+ and plain JavaScript or TypeScript 3. Uses the Postgres [`NOTIFY`](https://www.postgresql.org/docs/10/static/sql-notify.html) statement and subscribes to notifications using [`LISTEN`](https://www.postgresql.org/docs/10/static/sql-listen.html).\n\n### Features\n\n 📡 Send and subscribe to messages\n\n ⏳ Continuous connection health checks\n\n ♻️ Reconnects automatically\n\n ❗️ Proper error handling\n\n 👌 Type-safe API\n\n---\n\n\n## Installation\n\n```sh\n# using npm:\nnpm install pg-listen\n\n# using yarn:\nyarn add pg-listen\n```\n\n\n## Usage\n\n```js\nimport createSubscriber from \"pg-listen\"\nimport { databaseURL } from \"./config\"\n\n// Accepts the same connection config object that the \"pg\" package would take\nconst subscriber = createSubscriber({ connectionString: databaseURL })\n\nsubscriber.notifications.on(\"my-channel\", (payload) => {\n // Payload as passed to subscriber.notify() (see below)\n console.log(\"Received notification in 'my-channel':\", payload)\n})\n\nsubscriber.events.on(\"error\", (error) => {\n console.error(\"Fatal database connection error:\", error)\n process.exit(1)\n})\n\nprocess.on(\"exit\", () => {\n subscriber.close()\n})\n\nexport async function connect () {\n await subscriber.connect()\n await subscriber.listenTo(\"my-channel\")\n}\n\nexport async function sendSampleMessage () {\n await subscriber.notify({\n greeting: \"Hey, buddy.\",\n timestamp: Date.now()\n })\n}\n```\n\n\n## API\n\nFor details see [dist/index.d.ts](./dist/index.d.ts).\n\n\n## Error & event handling\n\n#### `instance.events.on(\"error\", listener: (error: Error) => void)`\n\nAn `error` event is emitted for fatal errors that affect the notification subscription. A standard way of handling those kinds of errors would be to `console.error()`-log the error and terminate the process with a non-zero exit code.\n\nThis `error` event is usually emitted after multiple attempts to reconnect have failed.\n\n#### `instance.events.on(\"notification\", listener: ({ channel, payload }) => void)`\n\nEmitted whenever a notification is received. You must have subscribed to that channel before using `instance.listenTo()` in order to receive notifications.\n\nA more convenient way of subscribing to notifications is the `instance.notifications` event emitter.\n\n#### `instance.events.on(\"reconnect\", listener: (attempt: number) => void)`\n\nEmitted when a connection issue has been detected and an attempt to re-connect to the database is started.\n\n#### `instance.notifications.on(channelName: string, listener: (payload: any) => void)`\n\nThe convenient way of subscribing to notifications. Don't forget to call `.listenTo(channelName)` to subscribe the Postgres client to this channel in order to receive notifications.\n\n\n## Why another package?\n\nIn one sentence: Because none of the existing packages was working reliably in production.\n\nUsing the `NOTIFY` and `LISTEN` features is not trivial using [`node-postgres` (`pg`)](https://www.npmjs.com/package/pg), since you cannot use connection pools and even distinct client connections also tend to time out.\n\nThere are already a few packages out there, like `pg-pubsub`, but neither of them seems to work reliably. Errors are being swallowed, the code is hard to reason about, there is no type-safety, ...\n\nThis package aims to fix those shortcomings. Postgres LISTEN & NOTIFY in node that finally works.\n\n\n## Debugging\n\nSet the `DEBUG` environment variable to `pg-listen:*` to enable debug logging.\n\n\n## License\n\nMIT\n","readmeFilename":"README.md","gitHead":"5756fe3dff87f2e88da276495a15e2757e24fb60","bugs":{"url":"https://github.com/andywer/pg-listen/issues"},"homepage":"https://github.com/andywer/pg-listen#readme","_id":"pg-listen@1.3.0-unhandled-rejection-fix","_nodeVersion":"10.15.3","_npmVersion":"6.9.0","dist":{"integrity":"sha512-uTd9DnjUOVu427h4IXmeT9m6/99KOpK1/gZz9AFmDNqFyzmjrU2iWexBDr9ez/aQcvnjo626RclLZ+9FZVzmSw==","shasum":"3f67d651291b36bf8dc5dade194c073bd80a4f10","tarball":"https://registry.npmjs.org/pg-listen/-/pg-listen-1.3.0-unhandled-rejection-fix.tgz","fileCount":7,"unpackedSize":27103,"npm-signature":"-----BEGIN

message broker: Send notifications with arbitrary payloads from one database client to others.\n\nWorks with node.js 8+ and plain JavaScript or TypeScript 3. Uses the Postgres [`NOTIFY`](https://www.postgresql.org/docs/10/static/sql-notify.html) statement and subscribes to notifications using [`LISTEN`](https://www.postgresql.org/docs/10/static/sql-listen.html).\n\n### Features\n\n 📡 Send and subscribe to messages\n\n ⏳ Continuous connection health checks\n\n ♻️ Reconnects automatically\n\n ❗️ Proper error handling\n\n 👌 Type-safe API\n\n---\n\n\n## Installation\n\n```sh\n# using npm:\nnpm install pg-listen\n\n# using yarn:\nyarn add pg-listen\n```\n\n\n## Usage\n\n```js\nimport createSubscriber from \"pg-listen\"\nimport { databaseURL } from \"./config\"\n\n// Accepts the same connection config object that the \"pg\" package would take\nconst subscriber = createSubscriber({ connectionString: databaseURL })\n\nsubscriber.notifications.on(\"my-channel\", (payload) => {\n // Payload as passed to subscriber.notify() (see below)\n console.log(\"Received notification in 'my-channel':\", payload)\n})\n\nsubscriber.events.on(\"error\", (error) => {\n console.error(\"Fatal database connection error:\", error)\n process.exit(1)\n})\n\nprocess.on(\"exit\", () => {\n subscriber.close()\n})\n\nexport async function connect () {\n await subscriber.connect()\n await subscriber.listenTo(\"my-channel\")\n}\n\nexport async function sendSampleMessage () {\n await subscriber.notify({\n greeting: \"Hey, buddy.\",\n timestamp: Date.now()\n })\n}\n```\n\n\n## API\n\nFor details see [dist/index.d.ts](./dist/index.d.ts).\n\n\n## Error & event handling\n\n#### `instance.events.on(\"connected\", listener: () => void)`\n\nThe `connected` event is emitted once after initially establishing the connection and later once after every successful reconnect. Reconnects happen automatically when `pg-listen` detects that the connection closed or became unresponsive.\n\n#### `instance.events.on(\"error\", listener: (error: Error) => void)`\n\nAn `error` event is emitted for fatal errors that affect the notification subscription. A standard way of handling those kinds of errors would be to `console.error()`-log the error and terminate the process with a non-zero exit code.\n\nThis `error` event is usually emitted after multiple attempts to reconnect have failed.\n\n#### `instance.events.on(\"notification\", listener: ({ channel, payload }) => void)`\n\nEmitted whenever a notification is received. You must have subscribed to that channel before using `instance.listenTo()` in order to receive notifications.\n\nA more convenient way of subscribing to notifications is the `instance.notifications` event emitter.\n\n#### `instance.events.on(\"reconnect\", listener: (attempt: number) => void)`\n\nEmitted when a connection issue has been detected and an attempt to re-connect to the database is started.\n\n#### `instance.notifications.on(channelName: string, listener: (payload: any) => void)`\n\nThe convenient way of subscribing to notifications. Don't forget to call `.listenTo(channelName)` to subscribe the Postgres client to this channel in order to receive notifications.\n\n\n## Why another package?\n\nIn one sentence: Because none of the existing packages was working reliably in production.\n\nUsing the `NOTIFY` and `LISTEN` features is not trivial using [`node-postgres` (`pg`)](https://www.npmjs.com/package/pg), since you cannot use connection pools and even distinct client connections also tend to time out.\n\nThere are already a few packages out there, like `pg-pubsub`, but neither of them seems to work reliably. Errors are being swallowed, the code is hard to reason about, there is no type-safety, ...\n\nThis package aims to fix those shortcomings. Postgres LISTEN & NOTIFY in node that finally works.\n\n\n## Debugging\n\nSet the `DEBUG` environment variable to `pg-listen:*` to enable debug logging.\n\n\n## License\n\nMIT\n","readmeFilename":"README.md","gitHead":"a1ed4f2ddd029aff5d29de4d36e5e56fdef600b6","bugs":{"url":"https://github.com/andywer/pg-listen/issues"},"homepage":"https://github.com/andywer/pg-listen#readme","_id":"pg-listen@1.3.2-connected","_nodeVersion":"10.15.3","_npmVersion":"6.9.0","dist":{"integrity":"sha512-4Ot4Rv6OavsGgcCD0t0kTYZlfokHNy9XufjRpm0oThSkPtJrjyxf50LBkTbqnHuI/bKz9KawkcAuVhZmeQ6LWQ==","shasum":"68755ef44df61ea1296eb71795dea5e7e5927fe3","tarball":"https://registry.npmjs.org/pg-listen/-/pg-listen-1.3.2-connected.tgz","fileCount":7,"unpackedSize":27754,"npm-signature":"-----BEGIN

\nPostgres LISTEN & NOTIFY that works
\n\n\n \n ![\"Build](\"https://travis-ci.org/andywer/pg-listen.svg?branch=master\")
\n \n \n ![\"NPM](\"https://img.shields.io/npm/v/pg-listen.svg\")
\n \n
\n\n
\n\nPostgreSQL can act as a message broker: Send notifications with arbitrary payloads from one database client to others.\n\nWorks with node.js 8+ and plain JavaScript or TypeScript 3. Uses the Postgres [`NOTIFY`](https://www.postgresql.org/docs/10/static/sql-notify.html) statement and subscribes to notifications using [`LISTEN`](https://www.postgresql.org/docs/10/static/sql-listen.html).\n\n### Features\n\n 📡 Send and subscribe to messages\n\n ⏳ Continuous connection health checks\n\n ♻️ Reconnects automatically\n\n ❗️ Proper error handling\n\n 👌 Type-safe API\n\n---\n\n\n## Installation\n\n```sh\n# using npm:\nnpm install pg-listen\n\n# using yarn:\nyarn add pg-listen\n```\n\n\n## Usage\n\n```js\nimport createSubscriber from \"pg-listen\"\nimport { databaseURL } from \"./config\"\n\n// Accepts the same connection config object that the \"pg\" package would take\nconst subscriber = createSubscriber({ connectionString: databaseURL })\n\nsubscriber.notifications.on(\"my-channel\", (payload) => {\n // Payload as passed to subscriber.notify() (see below)\n console.log(\"Received notification in 'my-channel':\", payload)\n})\n\nsubscriber.events.on(\"error\", (error) => {\n console.error(\"Fatal database connection error:\", error)\n process.exit(1)\n})\n\nprocess.on(\"exit\", () => {\n subscriber.close()\n})\n\nexport async function connect () {\n await subscriber.connect()\n await subscriber.listenTo(\"my-channel\")\n}\n\nexport async function sendSampleMessage () {\n await subscriber.notify(\"my-channel\", {\n greeting: \"Hey, buddy.\",\n timestamp: Date.now()\n })\n}\n```\n\n\n## API\n\nFor details see [dist/index.d.ts](./dist/index.d.ts).\n\n\n## Error & event handling\n\n#### `instance.events.on(\"connected\", listener: () => void)`\n\nThe `connected` event is emitted once after initially establishing the connection and later once after every successful reconnect. Reconnects happen automatically when `pg-listen` detects that the connection closed or became unresponsive.\n\n#### `instance.events.on(\"error\", listener: (error: Error) => void)`\n\nAn `error` event is emitted for fatal errors that affect the notification subscription. A standard way of handling those kinds of errors would be to `console.error()`-log the error and terminate the process with a non-zero exit code.\n\nThis `error` event is usually emitted after multiple attempts to reconnect have failed.\n\n#### `instance.events.on(\"notification\", listener: ({ channel, payload }) => void)`\n\nEmitted whenever a notification is received. You must have subscribed to that channel before using `instance.listenTo()` in order to receive notifications.\n\nA more convenient way of subscribing to notifications is the `instance.notifications` event emitter.\n\n#### `instance.events.on(\"reconnect\", listener: (attempt: number) => void)`\n\nEmitted when a connection issue has been detected and an attempt to re-connect to the database is started.\n\n#### `instance.notifications.on(channelName: string, listener: (payload: any) => void)`\n\nThe convenient way of subscribing to notifications. Don't forget to call `.listenTo(channelName)` to subscribe the Postgres client to this channel in order to receive notifications.\n\n\n## Why another package?\n\nIn one sentence: Because none of the existing packages was working reliably in production.\n\nUsing the `NOTIFY` and `LISTEN` features is not trivial using [`node-postgres` (`pg`)](https://www.npmjs.com/package/pg) directly, since you cannot use connection pools and even distinct client connections also tend to time out.\n\nThere are already a few packages out there, like `pg-pubsub`, but neither of them seems to work reliably. Errors are being swallowed, the code is hard to reason about, there is no type-safety, ...\n\nThis package aims to fix those shortcomings. Postgres LISTEN & NOTIFY in node that finally works.\n\n\n## Debugging\n\nSet the `DEBUG` environment variable to `pg-listen:*` to enable debug logging.\n\n\n## License\n\nMIT\n","readmeFilename":"README.md"}
