I'm using Sequelize and I'm currently creating migrations for my nodejs-application.
How can I regenerate the migration files when I changed the models?
Using npx sequelize-cli model:generate will create a migration file automatically. I want to generate these files without creating a new model.
Thinks in Advance!

I have sequelize-cli installed globally.
When I run the command
sequelize model:create --name User --attributes name:string,email:string,password:string
it creates the model at models/user.js and migration at migrations/20201115094126-create-user.js
Both the files are created in Javascript. I want both the model and migration to be created in Typescript. In the documentation, I have only found the manual creation of models. Is there a way to create these files in Typescript?
So I've added a relation to my SQLite database and now I want to update my entities in typeorm. Do I have to do this manually or is there a way with which I can generate those new entities. I used typeorm-model-generator for the initial generation of the entities...
I also tried using the generate migration command of typeorm but this turned out being used for updating the database according to the entities I would have written. (code-first)
I'm researching the ability to generate migration files for existing models. For example if I use "force: true" mode, tables in database are creating automatically so I can't believe that creating migrations files automatically is impossible. So could you help me with advice?
I was able to work around this by creating migrations using sequelize-cli in JS file and importing it in my TypeScript file.
This way only the migrations are in JS while the other parts are in TS
I started to use Jhipster. I have existing entity in

I don't want to use jhipster command
yo jhipster:entity MyCustomEntity
How to update ddl using existing entity after manual change(entity creation/updating/deletion)?
Configure database properties in your pom.xml and use ./mvnw liquibase:diff to generate a Liquibase migration file that you will store in src/main/resources/config/liquibase/changelog directory and refer to it from src/main/resources/config/liquibase/master.xml
This is documented on JHipster web site
I just lost 11,000 records from my database just running the command for sailsjs without the --prod part in it, So I thought I should ask whats the best way to change the tables on production server when the Model.js has been changed ?
Thanks
Automated migration should never be done in production. This a common-sense practice that applies to any production system with important data. There are a few solutions available for migrating a sails.js database.
sails-db-migrate: db-migrate integration for sails.js
db-migrate integration for Sails.js. This is a fairly simple wrapper, which provides grunt tasks for running and creating migrations.
sails-migrations: The missing, migrations arm of the octopus
sails-migrations provides an easy way to manage database migrations with sails, based on the amazing https://github.com/tgriesser/knex lib. This means you can have fine-grained control over your schema/data transformations between versions.
Sequelize migrations
Sequelize 2.0.0 introduces a new CLI which is based on gulp and combines sequelize-cli and gulp-sequelize. The CLI ships support for migrations and project bootstrapping. With migrations you can transfer your existing database into another state and vice versa
