You can't update 1.x version of your ThinkJS project to 2.x directly.
Version 2.0 makes up of modules by default which is difference with version 1.x. If you want to use the structure of version 1.x in version 2.0, you should specify --mode=normal like following:
thinkjs new demo --mode=normalIn old versions, the filenames was camel-cased, and include file-type, such as Controller/indexController.js. Version 2.0 was build strictly based on the rule of Node.js community that all filenames and paths are lower-case and cut out file-type, so you can see such as controller/index.js. This new change makes filenames simple and easy to use in all platform.
With version 1.x, you need start debug mode in development environment and stop it in production environment. This can result in memory leaks because most people often forget do it in deploy process.
The debug mode was deprecated in version 2.x. The new version supports three modes: development, testing and production. Each mode has their own folder, you can start your project with different environment by using different folder.
The C method that used to get your configuration infomation in version 1.x was deprecated in version 2.0. In vesion 2.0, you read configuration infomation that in different places by using different methods.
In places that can acess http object such as Controller, Middleware, you can use config method to get configuration information, in other places you should use think.config method.
There were D and M methods to instantiate your model in verion 1.x. But in version 2.0 they are deprecated, you need instantiate your model in different places by using different methods.
In Controller, Model, Middleware, you can use model method for instantiating. In other places you should use think.model method.
There were Controller and Model methods could be used to create controllers and models in version 1.x. But in this new version, they both are deprecated. Instead of using these methods, we support various ways to instantiate classes.
You can use ES6 grammar class extends think.model.base to instantiate a model, and to instantiate a controller is same.
Version 1.x supports some common global methods such as md5, mkdir. All that was moved to think object since verion 2.0, so you can use think.md5, think.mkdir correspondingly.
common/In version 1.x, there is a directory common/, the files within it will be auto called. In version 2.x, that directory has renamed to bootstrap/, and must be placed in the common module directory, like src/common/bootstrap.
Version 2.0 changed Behavior and Driver to middleware and adapter.
Version 1.0 provided a simple bash file named ctrl.sh for us to manage the Node.js services. But with version 2.0, we removed it and advice you take pm2 to replace it. We provide a default pm2's config file named pm2.json, so you can run pm2 start pm2.json to start service.
