docker-compose down Database configuration 🔗 Note The tool docker-compose needs to be natively installed on your machine. With the docker-compose configuration specified, the docker-compose tool can be run. The data is persisted on a named docker volume database-data. The database port 5432 is exposed on localhost:5432 such that the Node application npm start can access it. It has a fixed user, database name and password. The file docker-compose.yml specifies that a Postgres database should be running.
database -data :/var/lib/postgresql/data/ Local docker database 🔗įirst, we create a file docker-compose.yml to manage the local Postgres database. You can read in a different post why TypeScript is awesome for SQL queries. Postgres is an SQL database which we can access with the Node.js library Knex and the relevant Postgres driver. We are setting up a local Postgres database with docker-compose for our Node.js service such that we can persist data.Ī database allows us to persist data beyond the lifetime of the application. Node.js Microservice Architecture Connecting a Node.js app with a Postgres database Dropping support for an old node lts version will always be considered a breaking change in node-postgres and will be done on major version number changes only, and we will try to keep support for 8.x for as long as reasonably possible.Connecting a Node.js app with a Postgres database Back to main page Menu At the time of this writing node-postgres is compatible with node 8.x, 10.x, 12.x and 14.x To use node >= 14.x you will need to install or later due to some internal stream changes on the node 14 branch. Node-postgres strives to be compatible with all recent lts versions of node & the most recent "stable" version. If you or your company would like to sponsor node-postgres stop by github sponsors and sign up or feel free to email me if you want to add your logo to the documentation or discuss higher tiers of sponsorship! Version compatibility Node-postgres continued development and support is made possible by the many supporters.
