Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
modli-postgres
Advanced tools
This module provides adapter for the PostgreSQL datasource for integration with Modli.
npm install modli-postgres --save
When defining a property which will utilize the adapter it is required that a
tableName
be supplied:
const { model, adapter, obey, use } = require('modli')
const postgres = require('modli-postgres')
model.add({
name: 'foo',
version: 1,
tableName: 'tblFoo'
schema: obey.model({
id: { type: 'number' },
fname: { type: 'string', min: 3, max: 30 },
lname: { type: 'string', min: 3, max: 30 },
email: { type: 'email', min: 3, max: 254, required: true }
})
})
Then add the adapter as per usual with the following config object structure:
adapter.add({
name: 'postgresFoo',
source: postgres
config: {
host: {HOST_IP},
user: {USERNAME},
password: {PASSWORD},
database: {DATABASE}
}
})
You can then use the adapter with a model via:
// Use(MODEL, ADAPTER)
const postgresTest = use('foo', 'postgresFoo')
The following methods exist natively on the PostgreSQL adapter:
query
Allows for passing standard PostgreSQL queries:
postgresTest.query('SELECT * FROM tblFoo')
.then(/*...*/)
.catch(/*...*/)
createTable
Creates (IF NOT EXISTS
) a table based on params:
postgresTest.createTable({
'id': [ 'serial', 'NOT NULL', 'PRIMARY KEY'],
'fname': [ 'varchar(255)' ],
'lname': [ 'varchar(255)' ],
'email': [ 'varchar(255)' ]
})
.then(/*...*/)
.catch(/*...*/)
create
Creates a new record based on object passed:
postgresTest.create({
fname: 'John',
lname: 'Smith',
email: 'jsmith@gmail.com'
})
.then(/*...*/)
.catch(/*...*/)
read
Runs a SELECT
with optional WHERE
:
postgresTest.read('fname=\'John\'')
.then(/*...*/)
.catch(/*...*/)
update
Updates record(s) based on query and body:
postgresTest.update('fname=\'John\'', {
fname: 'Bob',
email: 'bsmith@gmail.com'
})
.then(/*...*/)
.catch(/*...*/)
delete
Deletes record(s) based on query:
postgresTest.delete('fname=\'Bob\'')
.then(/*...*/)
.catch(/*...*/)
extend
Extends the adapter to allow for custom methods:
postgresTest.extend('myMethod', () => {
/*...*/
})
The PostgreSQL adapter requires the following environment variables to be set for running the tests. These should be associated with the PostgreSQL instance running locally.
MODLI_POSTGRES_HOST,
MODLI_POSTGRES_USERNAME,
MODLI_POSTGRES_PASSWORD,
MODLI_POSTGRES_DATABASE
This repository includes a base container config for running locally which is located in the /docker directory.
