east sqlite

sqlite adapter for east (node.js database migration tool) which uses 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:

Installation

npm install east east-sqlite -g

alternatively you could install it locally

Usage

go to project dir and run

east init

create .eastrc file at current directory

{
    "adapter": "east-sqlite",
    "dbFile": ""
}

where dbFile is file of database which you want to migrate

now we can create some migrations

east create apples
east create bananas

created files will looks like this one

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

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

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

east migrate

output

target migrations:
    1_apples
    2_bananas
migrate `1_apples`
migration done
migrate `2_bananas`
migration done

and roll them back

east rollback

output

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.

east migrate 1_apples

or

east migrate 1_apples,2_bananas
