Use in NestJS-mod

An example you can see the full example here https://github.com/nestjs-mod/nestjs-mod-contrib/tree/master/apps/example-prisma-flyway.

import { PACKAGE_JSON_FILE, ProjectUtils, bootstrapNestApplication } from '@nestjs-mod/common';
import { DOCKER_COMPOSE_FILE, DockerCompose, DockerComposePostgreSQL } from '@nestjs-mod/docker-compose';
import { FLYWAY_JS_CONFIG_FILE, Flyway } from '@nestjs-mod/flyway';
import { join } from 'path';

export const flywayPrismaFeatureName = 'flyway-prisma';

const rootFolder = join(__dirname, '..', '..', '..');
const appFolder = join(rootFolder, 'apps', 'example-prisma-flyway');

bootstrapNestApplication({
modules: {
system: [
ProjectUtils.forRoot({
staticConfiguration: {
applicationPackageJsonFile: join(appFolder, PACKAGE_JSON_FILE),
packageJsonFile: join(rootFolder, PACKAGE_JSON_FILE),
envFile: join(rootFolder, '.env'),
},
}),
],
infrastructure: [
DockerCompose.forRoot({
configuration: {
dockerComposeFileVersion: '3',
dockerComposeFile: join(appFolder, DOCKER_COMPOSE_FILE),
},
}),
DockerComposePostgreSQL.forRoot(),
DockerComposePostgreSQL.forFeature({
featureModuleName: flywayPrismaFeatureName,
}),
Flyway.forRoot({
staticConfiguration: {
featureName: flywayPrismaFeatureName,
migrationsFolder: join(appFolder, 'src', 'migrations'),
configFile: join(rootFolder, FLYWAY_JS_CONFIG_FILE),
},
}),
],
},
});

After connecting the module to the application and npm run build and starting generation of documentation through npm run docs:infrastructure, you will have new files and scripts to run.

New scripts mostly package.json

{
"scripts": {
"_____flyway_____": "_____flyway_____",
"flyway:create:example-prisma-flyway": "./node_modules/.bin/nx run example-prisma-flyway:flyway-create-migration",
"flyway:migrate:example-prisma-flyway": "./node_modules/.bin/nx run example-prisma-flyway:flyway-migrate"
},
"scriptsComments": {
"flyway:create:example-prisma-flyway": ["Command to create new empty migration for example-prisma-flyway"],
