# east sqlite
sqlite adapter for [east](https://github.com/okv/east) (node.js database migration tool) which uses
[node-sqlite3](https://github.com/mapbox/node-sqlite3)
All executed migrations names will be stored at `_migrations` table in the
current database. Object with following properties will be passed to `migrate`
and `rollback` functions:
* `db` - instance of [node-sqlite3](http://github.com/mapbox/node-sqlite3/wiki/API#databaserunsql-param--callback)
## Installation
```sh
npm install east east-sqlite -g
```
alternatively you could install it locally
## Usage
go to project dir and run
```sh
east init
```
create `.eastrc` file at current directory
```js
{
"adapter": "east-sqlite",
"dbFile": ""
}
```
where `dbFile` is file of database which you want to migrate
now we can create some migrations
```sh
east create apples
east create bananas
```
created files will looks like this one
```js
exports.migrate = function(client, done) {
var db = client.db;
done();
};
exports.rollback = function(client, done) {
var db = client.db;
done();
};
```
edit created files and insert
to 1_apples
```js
exports.migrate = function(client, done) {
var db = client.db;
var sqlStr = 'insert into things values($id, $name, $color)';
db.run(sqlStr, {
$id: 1,
$name: 'apple',
$color: 'red'
}, function(err) {
if (err) return done(err);
db.run(sqlStr, {
$id: 2,
$name: 'apple',
$color: 'green'
}, done);
});
};
exports.rollback = function(client, done) {
var db = client.db;
db.run('delete from things where id in (1, 2)', done);
};
```
to 2_bananas
```js
exports.migrate = function(client, done) {
var db = client.db;
db.run('insert into things values($id, $name, $color)', {
$id: 3,
$name: 'banana',
$color: 'yellow'
}, done);
};
exports.rollback = function(client, done) {
var db = client.db;
db.run('delete from things where id=3', done);
};
```
now we can execute our migrations
```sh
east migrate
```
output
```sh
target migrations:
1_apples
2_bananas
migrate `1_apples`
migration done
migrate `2_bananas`
migration done
```
and roll them back
```sh
east rollback
```
output
```sh
target migrations:
2_bananas
1_apples
rollback `2_bananas`
migration successfully rolled back
rollback `1_apples`
migration successfully rolled back
```
you can specify one or several particular migrations for migrate/rollback e.g.
```sh
east migrate 1_apples
```
or
```sh
east migrate 1_apples 2_bananas
```
