Having trouble creating TypeScript models with sequelize-auto

I am currently faced with a dilemma where I need to integrate sequelize with an existing MySQL database. To simplify the process, I decided it would be best to use a code generator to create the necessary Models for sequelize.

After some research, I stumbled upon sequelize-auto and managed to successfully generate the required Models within my codebase.

Upon reviewing the documentation, I discovered that the generator command offers various optional flags. One of these options is -z or --typescript, which is supposed to produce the Models as typescript files. However, despite using this flag, the generated code still appears in js format with .js file extensions.

Despite searching for solutions from others who may have encountered similar challenges, I came up empty-handed.

Does anyone have any insights into what steps I might be overlooking?

The command I executed is as follows:

sequelize-auto -h myDb -d database_name -u some_user -x some_password -p 3306 -e mysql -o src/models -C --typescript

Thank you for your help!

Answer №1

It seems like the version of sequelize-auto that you are using is not up to date. You can verify this by checking if 

.node_modules/sequelize-auto/lib/ts-helper.js
exists in your project directory. If it is missing, then it indicates that your version of sequelize-auto does not match the current version on the repository.

To quickly resolve this issue, you can run 

yarn add https://github.com/sequelize/sequelize-auto
to use the version available in the repository as a node module instead of the latest stable release.

Updates related to typescript support in sequelize-auto are being implemented through pull requests. It is advisable to switch back to a stable release once one becomes available with the changes you require.
