Stop app on unapplied migrations ?

[shrynx]

Hi !

i am trying if i can achive the following,
in production when the app is about to start, check if all the migrations have been applied, if not then crash the app.

i am not sure if

• this code should live on provider boot method ?
• i want this to only apply for server and not cli etc
• how do i check if any migrations are pending or failed ?
• is stopping the app as simple as process.exit(1)

added the following as a provider and it works well

import app from "@adonisjs/core/services/app";
import type { ApplicationService } from "@adonisjs/core/types";
import { MigrationRunner } from "@adonisjs/lucid/migration";
import db from "@adonisjs/lucid/services/db";

export default class MigrationCheckProvider {
  constructor(protected app: ApplicationService) {}

  async start() {
    if (this.app.getEnvironment() === "web") {
      const migrator = new MigrationRunner(db, app, {
        direction: "up",
        dryRun: true,
      });
      const migrations = await migrator.getList();
      const incompleteMigrations = migrations.filter(
        (m) => m.status !== "migrated",
      );
      if (incompleteMigrations.length > 0) {
        console.error(
          `Pending Migrations${incompleteMigrations.map((m) => `\n${m.name} - ${m.status}`)}`,
        );
        if (app.inProduction) {
          console.error("Exiting due to pending migrations");
          process.exit(1);
        }
      }
    }
  }
}
